Session I: Inaugural session

On the occasion, Dr Gurbachan Singh, Chairman, Agricultural Scientists

Recruitment Board, New Delhi was the chief guest while Dr J.S. Sandhu, Deputy Director General (Crop Sciences), Indian Council of Agricultural Research (ICAR)

was the guest of honour. Dr Baldev Singh Dhillon, Vice-Chancellor, PAU presided over the inaugural session. Besides, Dr Amarjit Singh Khera, former Vice-

Chancellor, PAU; Dr S.K. Sharma, Chairman, Research Advisory Committee, Indian Institute of Maize Research (IIMR), New Delhi; and Dr I.S. Solanki, Assistant Director General (Food and Fodder Crops), ICAR were the special

guests. Dr O.P. Yadav, Director, IIMR also shared his views during the workshop.

In his inaugural address, Dr Gurbachan Singh said maize crop is

ecologically suitable for Punjab, Haryana and western Uttar Pradesh. Its cultivation must be promoted among the farmers for it has a great scope in terms of marketing, processing and value addition, he added. ―According to

contemporary farm scenario, many farmers are cultivating small land holdings,‖ he pointed out, while emphasizing on adopting integrated farming approach.

With declining profits and increasing cultivation costs, maize can play a vital role in sustaining productivity, he said. Stating, ―We need to produce more from less area and less water,‖ Dr Singh said water share, in the next 20 years, may drop

from 80 per cent at present to 72 per cent. The power of new sciences such as nanotechnology and biotechnology must be used in various crops, he advised.

Besides, he urged the maize experts to lay stress on density management in maize. In his address, he stressed that yield gap at village, district, state and national level must be analyzed critically followed by an out-of-box thinking to

further augment maize productivity of country. He also advocated to adopt an integrated farming approach and emphasized that efficiency use of water,

energy and nutrients needs to be improved in maize to make it more climate-resilient.

The guest-of-honour on the occasion, Dr. J.S. Sandhu, Deputy Director

General (Crop Sciences), highlighted that hybrid breeding needs greater focus, and research on suitable maize germplasm with tolerance to both drought and

water-logging conditions is required. Dr Sandhu said maize is a unique crop and has multiple uses in terms of feed, food, fodder and fuel. ―The productivity of maize is highest in Tamil Nadu with 5.4 tonnes, Punjab - 4 tonnes, Haryana - 3

tonnes, Uttar Pradesh -1.8 tonnes,‖ he disclosed. In Punjab, Kapurthala, Hoshiapur, Patiala, Shaheed Bhagat Singh Nagar and Tarn Taran districts have

contributed significantly to the enhancement of maize productivity, he said. Calling maize a climate resilient crop, Dr Sandhu stressed on focusing on crop management as well as demand-supply.

In his presidential address, Dr. B.S. Dhillon, traced the history of maize breeding and called upon for greater infusion of science in maize research. Dr

Dhillon, while highlighting the achievements of PAU maize section, underlined the need for change in stereotype research and improvement in quality of

testing. Quality protein maize needs to be pushed, he said, while suggesting focusing on marker assisted selection and double haploid technology in maize breeding. Since maize is a promising crop for diversification, there is a need to

study its nutritional value too, he added. Dr Dhillon also emphasized on addressing the issue of climate variations, he added.

7

Referring to Prime Minister, Narendra Modi’s ―Make in India‖ campaign, Dr A S Khera called upon the maize scientists to develop their own varieties and

have their own public-private partnership. He said major emphasis should be on maize and cotton as both the crops are wide spacing. In addition, attention

should also be paid to crop improvement, he added.

Dr Sharma observed maize research has undergone a sea change in the last few years. The challenges of genetic enhancement and strengthening of

seed production progarmme need to be addressed, he observed. He congratulated the maize scientists for the upgradation of Directorate of Maize

Research to Indian Institute of Maize Research.

Dr I.S. Solanki said maize is the third most important cereal crop of the country. Therefore, it should be popularized among farmers, industry and

consumers, he added. More thrust is being laid on single cross hybrids as they have shown resistance to various insect-pests and tolerance to drought, he

observed. Dr Solanki also stressed on setting-up of industries in the areas where maize is grown in volumes. Speaking on the occasion, he pointed out that maximum benefit from the hybrid technology is seen in maize.

Dr. O.P. Yadav, Director, IIMR reviewed the maize improvement work carried out during 2014-15 and informed that maize recorded the highest

production of 24.35 million tonnes during 2014-15 that has been made possible through flagship role of AICRP on maize. During last year, 17 new hybrids and

varieties were released for different states of country. According to the 12th Plan of ICAR, five new Centers on Maize are set to come up in West Bengal, Bihar, Maharashtra and in remote areas, he revealed.

Earlier, Dr Balwinder Singh, Director of Research, PAU while welcoming the dignitaries and the delegates, said the maize production has doubled in the

past few years and by 2025, its production is expected to escalate all the more. ―Grown in 160 countries, maize is the first crop to benefit from hybridization,‖ he highlighted. PAU has the credit of developing first single cross maize hybrid, he

disclosed, while adding the university has released 41 high yielding composites/hybrids of maize so far. The cultivation of sweet corn, baby corn and

quality protein maize can give additional income to the farmers, he added.

Dr H.S. Dhaliwal, Dean, College of Agriculture, proposed the vote of thanks. On the occasion, a souvenir and a CD on annual report of AICRPM 2014

were released. Besides, Best AICRP Centre Award was bestowed on Tamil Nadu Agricultural University, Punjab Agricultural University and a maize hybrid

producing firm. In addition, certificates were distributed for the protection of plant varieties and Farmers’ Rights Act. During this session, Dr. A.S. Khehra, Former Vice-Chancellor and Dr. B.M. Prasanna, Maize Geneticist were felicitated

for their contributions to maize research.

Breeding

The session was started with presentation on promotions of entries in different

maturity groups namely late, medium, early and extra-early from IVT to AVT-I

and AVT-I to AVT-II. In the course of presentation several observations were

made and the following points were emerged after thorough discussion. The

details of the entries promoted were discussed and finalized.

The coordinated trials may be split into different sets comprising 30-40 entries

per set if number of test entries exceeds 60.

1. It was decided to include zone specific check(s), which were released and notified for the zone, while constitution of coordinated trials.

2. The percentage superiority over best check of the zone, which was released and notified for the zone in late maturity group was increased to 10% from the earlier 5% for promotion from IVT to AVT-I.

3. The separate session was organized for researchers involved in conducting trial at voluntary centres as well as fresh researches joined in the AICRP

centres to appraise them how to generate appropriate quality data while conducting coordinated trials.

4. The separate maize biofortification trial for different quality traits like pro-

vitamin A will be constituted and executed at specific locations from Kharif 2015 to encourage trait specific breeding.

Crop production

The findings of 11 experiments conducted at 27 centres were presented by Dr A

K Singh, PI (Agronomy). The following points were suggested:

In cropping system based trials, data of previous season’s crops should be

incorporated in the presentation, so that complete recommendations may be

made.

The experiments completed three years should be analyzed and summarized

recommendations may be made.

The trials on weed and water management must be formulated for coming

season. Herbicide molecules will be arranged by PI Agronomy.

For intercropping trials having pulses as a component crop, discussion may

be made with the IIFSR, Modipurum and IIPR, Kanpur before finalization.

Comprehensive information including economics should be considered for

presenting the results.

Entomology

Dr. Pradyumn Kumar presented the results of Kharif 2014 and Rabi 2013-14

trials and summarized the results of resistant lines and hybrids identified for

Chilo partellus, Sesamia inferens in different coordinated trials. He presented the

incidence of cob borer complex, Helocoverpa armigera, Euproctis spp.,

Spodoptera in maize during grain filling stage across zones. Evaluation of bio-

control agents to control Chilo partellus and incidence of egg parasitoid and

larval parasitod, Cotesia on C. partellus in different zones was also presented. In

addition efficiency of different insecticides in controlling Chilo partellus along

with crop losses validation formulae was presented. Finally, he briefed on plant

volatile collection system for which a patent has been applied. He also presented

the information plant volatile collection system for which patent was filed.

Presentation ended with thanks to chair.

Pathology

Dr. KS Hooda presented the results of Kharif 2014 and Rabi 2013-14 trials and summarized the results of resistant lines and hybrids identified for different diseases in different coordinated trials. A total of 551 hybrids in both seasons

and 231 inbred lines (Kharif only) were screened against major diseases and Cyst nematode; and promising ones were identified. The avoidable yield loss in

Vivek Hybrid 5 at Almora due to TLB was 17.21% whereas Dhaulakuan centre recorded 35.98% yield loss due to MLB, CLS and BLSB. In addition, disease surveys were conducted at farmers’ fields in maize growing areas to assess

overall disease scenario during the crop season. Promising components for the management of disease and cyst nematode in maize were identified.

Session III

Panel Discussion - “Doubling maize production of India by 2025 –

Opportunities and challenges”

Chairman Co-chairman Rapporteurs

Dr. J.S. Sandhu, DDG (CS), ICAR

Dr B.M. Prasanna, Director Global Maize Programme, CIMMYT


Dr. Pranjal Yadava Dr. Chikkappa Karjagi

Dr. Bhupender Kumar

The session was chaired by Dr. J. S. Sandhu, DDG (Crop Science), ICAR and co-

chaired by Dr. B. M. Prasanna, Director, Global Maize Programme, CIMMYT. The

panellists included renowned scientists from public, private and international

organizations. The panellists deliberated about the top priorities that need to be

addressed in order to double the maize production of India in next 10 years.

Starting the deliberations, Dr. Usha Singh, RAU, Dholi emphasized intervention

thorugh government policy to provide farmers a remunerative price and also to

enhance quality of maize produce through mechanized harvesting with

community based driers, to bridge the yield gap (mainly kharif) by adopting

10

improved agronomic practices, creation new demand through product

diversification and inclusion of maize foods in mid day meal.

Dr. Hans Bhardwaj, Pioneer Hibred International, attracted the attention to

develop common maturity grouping system in India on the lines of

internationally accepted system, suggested to measure progress in terms of

genetic gain, to use prediction tools in plant breeding and to increase the

precision of plots to capture data accurately.

Dr. Dheeraj Pant, Monsanto India Pvt Ltd suggested bridging the yield gap

through popularization of scientific package of practices among farmers along

with enhanced associated extension system, better management of disease,

insect and weeds. He was of the opinion that, presently herbicide use is not

adequate in maize-based farming systems in India.

Dr. Bajinder Pal, Bioseed Ltd suggested for identifying productivity limitation of

different zone since there are different productivity zones of maize in India. He

highlighted that there are no limitations in high yielding rabi production zone

except storage infrastructure. In medium yielding zone of South India, leaf

diseases, stalk rots and drought are the major limiting factors as 25-30% area in

this zone is under drought. In medium yield zone of north India, there are

problem of excess water and stalk rot. In the low yield zone of North (viz., UP,

Bihar, Jharkhand) there are no specific products and farmers of this region grow

hybrids recommended for other zones. Similarly, for hill areas there are no good

genotypes available. He suggested six priority areas to double the maize

production by 2015 viz., to frame structured policy for germplasm exchange,

participatory germplasm enhancement system, to develop breeding centre for

different areas, working with policy makers to ensure remunerative price for

maize farmers, need for continuous monitoring of new and emerging challenges

and efforts to make corn a profitable crop.

Dr B. S. Vivek, CIMMYT, India suggested for use of doubled haploids, heterotic

organisation of germplasm and strengthening QPM programme along with high

oil, pro vitamin A and other traits for end users.

Dr M. L. Jat, CIMMYT, India suggested farming systems approach and cautioned

that the rice wheat system should not be repeated, to provide complete value

chain from maize production, marketing, availability to consumption along with

formulation of diverse farm situations.

Dr J. S. Chawla, PAU, Ludhiana suggested for accelerated breeding using DH and

MAS.

Dr J. P. Shahi, BHU, Varanasi suggested to address abiotic stresses like excess

moisture, drought etc., diversification of maize types like sweet corn and baby

corn in peri-urban agriculture, economically viable seed production system

especially for kharif season and contract farming to provide farmers a

remunerative price.

11

Dr G. Nalathambi, TNAU, Coimbatore suggested for appropriate management

technologies, input subsidies for seed and fertilizers, minimum wages to

labourers is required to stop rural migration and MSP regime needs to be

implemented more seriously, close working of agricultural scientists with

farmers, soil health and crop rotation needs to be specially strengthened.

Dr S. K. Guleria, AICRP Bajaura (H.P.) suggested to manage major diseases

bacterial stalk rots and BLSB along with making available of hybrid seeds from

public sector.

Dr Feroz Hussain, IARI, New Delhi suggested for structuring of germplasm based

on the heterotic pattern, introgressing QTLs for biotic, abiotic stresses as well as

nutritional quality traits in maize germplasm.

Dr O. P. Yadav, Director, IIMR, New Delhi suggested for diversification of

germplasm base and heterotic grouping of material, to increase the rate of

genetic gain through accelerated breeding, to develop stress resilient genotypes

for diverse ecologies of India, upscaling adoption of single cross hybrids in

different parts of India, strengthening public private partnerships and human

resource development along with finding a mechanism to absorb extra maize

production.

Dr S.K. Vasal eminent maize breeder focused on strength of maize crop and

drawn attention to adopt traits and technologies which have been very

successful in other cereal crops, like the use of dwarfing gene in maize. He

suggested using fundamental science in maize breeding, heterotic grouping and

developing pools and populations.

Dr S Dass stressed for bridging yield gap by pushing available technologies for

rapid adoption, mechanization of maize cultivation, quality hybrid seed

production supported with large scale seed driers at seed production hubs and

transgenics.

Dr B.S. Dhillon, Vice Chancellor, PAU, Ludhiana stressed for maize production

management, development of plant type for high density planting and genotypes

resistant to stresses, use of MAS, DH, offseason nurseries.

The session was opened for general discussion among the audience and

participants of the workshop. Various delegates highlighted different important

issues that were untouched by the panellist. Dr M.C. Kamboj, CCS HAU, Dr

Laxmikant, Kaveri Seeds, Dr I.S. Solanki, ADG (FFC), ICAR, Dr Vinay Mahajan,

IIMR, Dr Vijendar, Karnataka State Seed Corporation, Dr S.M. Khanorkar, GAU,

Dr K.H. Patel, AAU, Dr M.C. Wali, AICRP Arabhavi and others participated in the

discussion.

Dr B.M. Prasanna comprehended all suggestions made by different panellists in

five important strategies - the technology targeting, bringing more science in

breeding and increase the rate of genetic gain, translating genetic gain obtained

at experimental field to farmer’s fields on sustainable manner through transfer of

technology, focussing on seed producibility of maize hybrids and integration of

12

socio economic, markets and institutions. He suggested to assess the

performance of scientists by using quantified genetic gain and impacts not by

publications alone.

Concluding the deliberations, Dr J. S. Sandhu highlighted several issues like

reduction of cost of hybrid seeds, use of temperate germplasm in regular

breeding programme, focussing on breeding abiotic stress tolerant genotypes

and mechanization of maize production system. The panel discussion was very

fruitful and all the panellists and the participants were optimistic and unanimous

about the motion that maize production of India can definitely be doubled by

2025.

The following suggestions were emerged based on the observation made during

the presentations.

1) Centres were suggested to develop large number of new cross combinations

every year along with identification of economical seed production ability of inbred / female parents of hybrids.

2) The centres whose hybrids are being used as national check in AICRP trials were asked to produce sufficient quantity of hybrids seed and supply the required quantity in time to IIMR.

3) The centres were suggested to mention or provide source from which their inbred lines have been are developed.

4) The thrust need to be given on developing new inbred lines by recycling the existing inbred line by making pedigree crosses to diversify the existing germplasm base.

5) Most of the centres were concerned about their financial scarcity with the respect to pay and contingency.

However, the scientist of the Almora, Kangra, Jhabua, Kanpur, and Varanasi didn’t attend the meeting as well as not presented the findings while the findings

of Banswara and Delhi centre were sent to PI and responsible person presented. After presentation following points have emerged to further improve the agronomic research of the country:

21

In tillage experiments, soil must be sampled from three depths (0-5, 5-15 and 15-30 cm) for soil physical and chemical properties after three years

of experimentation. The BISA, Ludhiana trial on water management in maize will be part of

AICRP maize. The weather data must be supplied with crop data. Publications should be made from the experiments completed three

cycles. Herbicides molecules will be arranged by PI Agronomy for weed

management trial. Data should be submitted in prescribed format as per the decided

treatments only otherwise data will not be included in report

The official communication Emails are [email protected] and [email protected]

The last date for submission of research data will be up to 15th December for Kharif and up to 1st August for Rabi season. Data received after these dates will not be included in report.

The group thoroughly discussed the achievements made in last year to make some recommendations out of the experiments conducted. It was decided the consistent results of the two year multi-locations experiments must go to

farmers filed as technologies. In this regard, the group came out with two following recommendations

Under rain fed conditions residue retention @ 5 t/ha on the soil surface is

recommended for enhancing maize productivity by 9-29%.

The intercropping of soybean/black gram in maize grown during kharif

season is recommended for Zone I, III and V.

After this the group discussed the work plan for the kharif 2015 and rabi 2015-16 trial-wise. The group made many suggestions in the conduct protocols of the experiment and approved them unanimously in nine ongoing experiments. In

view to have better water and weed management the group formulated two new trials on these aspects for enhancing maize production. The data to be recorded in all trials were thoroughly discussed and finalized for each experiment. In all,

eleven trials formulated to conduct during kharif 2015 and Rabi 2015-16 for agronomy programme were as follows:

Trials to be continued during 2013-14 1. Performance of pre-release genotypes under varying nutrients levels 2. Nutrient management in maize-wheat-green gram cropping system under

different tillage practices 3. Nutrient management in rice-maize cropping system under different tillage

practices 4. Nutrient management in maize-chickpea/mustard cropping system under

Session VI

Lead Lecture

The speaker of the session Dr. B. M. Prasanna, was introduced by the Dr. O.P.

Yadav, Director IIMR, New Delhi. In his introduction, Dr. O. P. Yadav highlighted

the achievements made by Dr. B. M. Prasanna as a scientist at IARI, New Delhi

and also as Director, Global Maize Programme, CIMMYT. Dr. S. K. Vasal, Eminent

Maize Breeder, CIMMYT highlighted the importance of the topic chosen which is

very pertinent in the present context and invited Dr. B. M. Prasanna to start the

presentation on a important topic ―Enhancing maize genetic gains and breeding

efficiency: status and prospects‖. In the presentation Dr. B. M. Prasanna touched

important aspect of maize breeding to increase the productivity of maize. The

major areas of importance are.

1. Increasing the genetic gain in the important traits

2. Bringing more area under improved varieties

3. Increasing the rate of turn-over of improved varieties with newly

developed varieties/hybrids.

He stressed for multi-dimensional approach for enhancing the maize production

and productivity. He stressed for development of improved varieties with stress

resilient traits as well as enhanced nutritional value and their cultivation under

improved production and management conditions. He emphasized on application

of new tools and techniques like MAS, MARS, genomic selection with doubled

haploid technique to increase the genetic gains, germplasm diversification and

enhancement through itrogression using off-PVP lines to develop stress resilient

maize genotypes for both biotic and abiotic streses. High throughput and

precise field phenotyping techniques and rapid cycle genomic selection for

complex traits like prolificacy, high vigour, stay green, higher yield, year round

nurseries for disease phenotyping, agronomic performance, stress tolerance etc.

can be used for to increase heritability of complex traits and selecting stable

genotypes.

In order to achieve rapid progress, understanding and diversifying germplasm

base, Unlocking functional diversity by systematic characterisation of germplasm

existed in gene bank will play significant role in future as well. He highlighted the

contributions made SUWAN-I, DTP and DTP-W and La Posta Sequia (LPS)

populations for enhancing the yield and also efforts of USA under GEM

programme and SeeD Initiative of CIMMYT for diversifying the genetic base and

characterization. He draws parallel Indian efforts by taking examples of Parbat,

Ageti 76 composites.

Finally he highlighted the importance of routine use of breeding data

management system (BDMS), biometrics and bioinformatics to increases the

efficiency of breeding and reduces the time to impact.

Session VII

ICAR-CIMMYT Collaborative Research

The presentation was made by Dr. Chikkappa GK on the summary of results of

trials conducted during kharif 2014. Several suggestions were made, namely the

presentation of results needs to be improved substantially by highlighting the

details of entries with superior performance, the results of agronomy

experiments conducted under ICAR-CIMMYT collaborative programme needs to

be included, information on utilization of CIMMYT germplasm also needs to be

presented, there is need to repeat the evaluation of best entries. Dr. SK Vasal

stresses on the need to integrate and utilize the best performing germplasm

material in the regular breeding programme of the AICRP centres as well as

IIMR. He emphasized to procure the best germplasm of their importance like

disease resistant germplasm, drought or water logging tolerant germplasm, high

yielding hybrids and their parental lines from CIMMYT through sending seed

indent and it the responsibility of CIMMYT to made available such germplasm.

Dr. A.R. Sadananda, proposed the new trials for 2015-16 and it was suggested

that CIMMYT need to indicate the source germplasm from which the germplasm

have been developed while proposing the trials for screening or phenotyping for

different traits. It was also suggested that the AICRP centres and IIMR, New

Delhi need to handle pedigree population to increase the utilization of CIMMYT

germplasm in regular breeding programme by developing wide genetic base in

the form of synthetic and composite. The trials were finalized under ICAR-

CIMMYT work plan are as follows.

Session VIII

Breeder Seed Production, FLDs and Training Programmes

Breeder Seed Production report for the year 2014

Status of breeder indented, allocated and produced during the kharif 2014 was

presented in detail by Dr. Jyoti Kaul. A total of 44.66 quintals of breeder seed of 33

cultivars (parental lines of 16 hybrids and 17 composites) was indented by DAC,

Govt. of India. The indent was allocated to centers during the 57th Annual Maize

Workshop to the centers. A total of 27.68 quintals of breeder seed was produced

during kharif 2014. Some of the centers are taking up breeder seed production

during rabi 2014-15 and spring 2015. This year BSP-V received only from VPKAS,

Almora center.

Among the centers, IARI, New Delhi and CSAU, Kanpur did not communicate

Breeder seed reports consecutively for two years. Apart from the DAC indent IIMR,

Begusari center has produced 12.5 quintals of Breeder seed of one of the parents of

HQPM-1, HKI-163 during kharif-2014. During rabi 2014-15, the center gave a

projection of 40 quintals seed production of HKI-193-1 and HKI-163.

Dr. Kaul sensitized all the breeders and center In-charges about the

importance of BSP-I, II, III, IV and V reports. And, she also encouraged centers to

submit the reports in time in prescribed format. Dr. Narsimha Reddy (ANGARU,

Hyderabad) raised the issue of very low quantity indent of Priya Sweet Corn

composite. He suggested that such low quantity indents should not be made as it

poses problem in certification. Dr. Sain Dass’s views were in affirmation to Dr.

Reddy’s. Chairman reiterated the importance of timely submission of BSP reports.

Outreach program (FLDs and TSP)

Dr. Ashok Kumar presented a complete account of Front Line Demonstrations

(FLDs) on maize technologies taken up during rabi 2013-14, spring 2014 and kharif

2014 was presented by Dr. Ashok Kumar. A total of 3433 FLDs were conducted on

various production technologies including specialty maize.

The FLD results seemed very encouraging; in all the cases the FLD average

yield was higher than state average yield. Honorable chairman of the session Dr.

Solanki pointed out that in Rajasthan, spring season FLD yield was three times

(>300%) the state average but was just 3% higher during kharif. The Tribal Sub

Plan (TSP) was successfully done during the reporting period. A total of 10 trainings

were imparted to 396 tribal farmers. The farmers were also made aware of value

addition during the training program. Two field days were conducted under TSP at

Aterna and Manauli village of Haryana and one at RMR& SPC, Begusarai. Farmers

were also given farm inputs during the field days.

Dr. Kamboj raised the issue of timely availability of funds to conduct FLDs

without difficulty and requested for timely allocation and release of funds. The same

issue was also raised by few more centers.

Session IX

Germplasm exchange, registration & seed issues

This session was chaired By Dr. Sain Dass , Ex Project Director, IIMR and co-chaired by Dr. IS

Solanki Asstt. Director General (FFC), ICAR, New Delhi.The rapporteurs were Dr. Jyoti Kaul,

Dr. BS Gill and Dr. CK Karjagi.

Following presentations were made:

1. Dr. JC Sekhar made an exhaustive presentation on Germplasm Exchange by

IIMR.During his presentation he described the various activities undertaken during the

year to facilitate germplasm exchange under the aegis of IIMR including organizing the

germplasm day during which the breeders from AICRP (Maize) centres were invited to

select the material as per their requirement.

2. Dr. A.R. Sadananda from CIMMYT, Hyderabad presented the status of germplasm

exchange under the aegis of CIMMYT.He highlighted the exchange of accessions

between CIMMYT - AICRP (maize) centres including IIMR and private sector in India.

3. Dr. J Kaul, IIMR presented the procedure for registration of germplasm with NBPGR

and PPVFRA. She explained the routes that may be followed for filing applications . The

new format developed by NBPGR was also discussed . The requirements for registration

were deliberated upon and breeders impressed to follow time-lines.

The meeting ended with the vote of thanks to the chair

Session X

General discussion

Director Maize has announced that this time IIMR will conduct National

demonstration in large size plots and include all commercial hybrids of public

and private sector.

Benchmarking of variety/hybrids for promotion from IVT to AVT I and AVT II

must be there and this will be 10% increase over best check irrespective of

maturity group.

Disease incidence data must be included as promotion criteria.

Centres contributing too many entries so it has been decided that one centre

can contribute only two entries in IVT.

In AVT II Quality analysis will also be done for protein %, Starch, Methionine

and other quality parameters. Procedure for taking samples for quality

analysis will be communicated so that proper sample could be sent to

Biochemistry laboratory for quality analysis.

Choice of checks: Latest check will be used in each maturity group (hybrid

released in last 3 years) and out of which best check (Public/Private) will be

used.

39

QPM trials: Proper Seed samples are not sent for quality analysis, QPM and

non QPM mixture has been reported by Biochemist. So, it is requested to

send only selfed samples to IIMR for quality analysis.

Guidelines for conducting trials will be uploaded on IIMR website

Baby corn trials: visit website to know which traits you have to record.

IIMR will upload the guidelines for the list of traits for specialty corns.

It is required to assess all material for its nutritional status; it will be under

bio -fortification project.

Trials on Bio-fortification: Director asked CIMMYT and IARI to help in

conducting these trials. In this regard Dr. Feroz Hussain, IARI, New Delhi

presented how these trials will be conducted. He elaborated the importance

of Fe, Zn, Phytic acid, lysine, tryptophan and beta–carotene.

Selfing of 03 cobs/rep/genotype—enough seed will be available for analysis.

Issues in data handling:

Suggestions to AICR partners: Check data before sending to IIMR.

Visit IIMR website for the excel sheet which has been developed for

recording data, use that only.

Please check outliers also.

Observations of AICRP scientists Response/comments

Dr G Nallathambi On entry contribution by centres, the

two entry are too less, by this way public institutions contribution will be

affected. We should take samples for quality analysis from 4 or 5 centres only. How the seed production issues

for hybrid should be addressed?

Dr. O.P. Yadav Once the hybrid is released, Director

will write a letter to state seed corporations as well as to NSC for seed

production.

Dr S.M. Khanorkar

There is need to allow every centre to contribute minimum 3-4 entry. The

test hybrids can be tested at Farmers field or not. Can we use this data? Decoded list may be provided to the

centres in the month of January or February.

Dr. O.P. Yadav

Pre-released hybrids are not allowed in FLD though you can generate data

from farmer’s field. Decoded list cannot be provided till

IIMR receive data from each and every centre

Dr JS Chawla Regarding outliers: one hybrid is at 1st

position at one place and at 40th position at another place—it may be due to fault in the way the trial is

conducted at centres. When we are talking for PPP, private firms must be

asked for research funding also. Some conduct under rainfed

Dr. O.P. Yadav

It has been observed that within location there is much variation in data, if the trial mean is low as

compared to state average—data may not be considered.

Irrigated vs Rainfed: we must have guidelines for specific centres

40

Observations of AICRP scientists Response/comments

conditions—such data should not be included. Centres must implement

proper plan provided by IIMR Dr SK Guleria Variation in data, we must use

monitoring reports also while considering the data of a particular

location. The centres which are not having irrigation facilities , they must inform that they cannot conduct trials

or IIMR may not provide trials to such centres

Dr JS Chawla Coding of trials: IIMR is also in fray and contributing hybrids, who will

handle coding?

Dr Solanki: don’t irrigate the rainfed trials

Dr Khanoorkar: At flowering only irrigation is must

Dr IS Solanki, ADG(FFC) suggested doubling coding , One coding with IIMR

and second coding with selected AICRP centre. The pattern of wheat group

may also be adopted.

Promotion of entries and technical programme-Crop improvement

In the kharif 2014, total of 414 test entries were evaluated in 15 different

breeding trials of various maturity group and types of corns

Of 414 entries, 374 were in normal and 40 were in specialty corns which

include QPM (12), sweet corn (13), baby corn (7) and popcorn (8).

Total of 396 test entries [IVT (297), AVTI (67), Specialty corns trials (32)]

were available for promotion from their current evaluation stage to next stage of testing, of which 87 were promoted.

Entries (Listed below) were promoted based on yield superiority over the best check (5 % in Late (AVT I) and specialty corns trials and 10% in Late

(IVT), medium, early and extra early). Further days to 50% silking was considered as another criteria of promotion besides yield superiority in Medium, early and extra early trials.

Annexure I

Guidelines for Uniform Method of Disease Assessment in Maize

Under Artificially/ Sick Plot Created Epiphytotics The screening techniques and rating of the disease intensities for uniform

assessment of maize diseases are given below:

1. Turcicum leaf blight (TLB) and maydis leaf blight (MLB)

Sorghum grains soaked in water in a conical flask, autoclaved twice, seeded with

fungus under aseptic condition are kept for incubation at 25-270C. The flasks are shaken once in 2-3 days to facilitate uniform growth on grains. After 10 days the

material is ready for inoculation. Prepare a fine powder of impregnated sorghum grains after shade drying. Put a pinch of this powder in the leaf whorl of 30-35 days old plant. Maintain adequate moisture for longer period to permit spore germination

with the help of sprayer. Disease can also be created by spraying the spore suspension prepared from the pure culture of fungi or placing a pinch of leaf meal

(prepared by grinding dried diseased leaves collected from the previous season) into whorl of each plant at 30-35 centimeter plant height with spray of 10-12 ml of water in whorl in case of dry weather. Second inoculation can be followed if the

symptoms do not appear even after a week of first inoculation. Data can be recorded on 30-35 days after inoculation following rating scale of Payak and

Sharma# (1983) mentioned below:

Rating

scale

Disease severity (%) PDI* Disease reaction

1.0

Very slight to slight infection, one or

two to few scattered lesions on lower leaves

20.0 Resistant

(Score: ≤ 2.0) (PDI: ≤ 40.0)

2.0 Light infection, moderate number of lesions on lower leaves only

40.0

3.0 Moderate infection, abundant lesions on lower leaves, few on middle

leaves

60.0 Moderately resistant (Score: 2.1 – 3.0)

(PDI: 40.1 – 60.0)

4.0

Heavy infections abundant on lower

and middle leaves, extending to upper leaves

80.0

Moderately susceptible

(Score: 3.1 – 4.0) (PDI: 60.1 – 80.0)

5.0 Very heavy infection, lesions abundant on almost all leaves plants prematurely dry or killed by the

disease.

100.0 Susceptible (Score: ≥4.1) (PDI: ≥ 80.0)

*Percent disease index (PDI)

2. Banded leaf and sheath blight (BLSB)

Soak barley grains in water for 24 hours and dispense 40g in 250 ml

Erlenmeyer flask after removing excess water; autoclave at a pressure of 1.05 kg/sq. cm for 30 minutes. Homogenize 2-3 days old growth of pathogen taken from potato dextrose agar in sterile water and seed 5 ml in each flask. Incubate at 27°C

for 10 days. Inoculations should be made during the rainy season on 30-45 days old plants with grain culture (2-4 grains) inserted between stalk and sheath at

75

second or third level from soil. Grains placed at junction of sheath and leaf can also create optimum disease level and do not fall away with strong wind or heavy rain.

Disease is recorded 45 days after inoculation on basis of following rating scale of Payak and Sharma#(1983).

Rating scale


1.0 Disease on one leaf sheath only; few small, non-coalescent lesions present

20.0 Resistant

(Score: ≤ 2.0) (PDI ≤ 40.0)

1.5 Disease on two sheaths: lesions large and coalescent

30.0

2.0 Disease up to four sheaths; lesions many and always coalescent

40.0

2.5 As in disease rating symptoms of 2.0 + rind discolored with small lesions

50.0 Moderately resistant

(Score: 2.1 - 3.0) (PDI 40.1 - 60.0) 3.0

Disease on all sheaths except two internodes below the ear

60.0

3.5 Disease up to one internode below ear shoot; rind discoloration on many internodes with large depressed lesions

70.0 Moderately susceptible

(Score: 3.1 - 4.0) (PDI 60.1 - 80.0)

4.0 Disease up to the internode bearing the ear shoot but shank not affected

80.0

4.5

Disease on the ear; husk leaves show bleaching, bands and caking among

themselves as also silk fibres; abundant fungal growth between and on kernels;

kernel formation normal except being lusterless; ear size less than normal; some plants prematurely dead

90.0

Susceptible (Score: ≥ 4.0) (≥ 80.0)

5.0 In addition to disease rating symptoms of 4.5, shrinkage of stalk; reduced ear

dimensions, wet rot and disorganization of ear; kernel formation absent or

rudimentary; prematurely dead plants common; abundant sclerotial production on husk leaves, kernels, ear tips and

stalk fibres

100.0


3. Brown stripe downy mildew (BSDM)

Artificial epiphytotic conditions can be created by placing the powdered

infected maize leaves containing spores collected during the last season containing oospores in furrows just before planting. This inoculum could also be prepared by collecting infected leaves supposed to be full of oospores from early plantings of

maize of the same season, drying leaves and making powder out of the debris. Inoculum should be placed in furrows in such a manner that seeds were in

proximity of inoculum.

76

Artificial epiphytotic condition could also be created by putting 2-3 cm pieces of freshly infected leaves containing sporangia of the fungus in the whorls of

seedlings. This should be done during cloudy weather in the evening between 5 and 7 P.M. at 17, 24 and 30 days after planting. In experimental plots, where disease

occurs year after year, only this method is adequate for creating epidemics. In areas of low disease incidence, both the methods of inoculation can be combined to obtain better results. Disease rating of individual maize varieties can be done by

evaluation all plants of the row (s) using 1-5 rating scale of Payak and Sharma# (1983) as described below:

Rating

scale


1.0 Very slight infection, one or two to few

scattered lesions on lower leaves 20.0

Resistant (Score: ≤ 2.0) (PDI: ≤ 40.0)

2.0 Light infection, a few scattered to

moderate number of stripes on lower leaves

40.0

3.0 Moderate infection, abundant stripes on

lower leaves and few on middle leaves 60.0

Moderately resistant (Score: 2.1 - 3.0) (PDI: 40.1 - 60 .0)

4.0 Heavy infection, stripes abundant on lower and middle leaves extending to

upper leaves

80.0 Moderately susceptible (Score: 3.1 - 4.0)

(PDI: 60.1 - 80 .0)

5.0

Very heavy infection, stripes abundant

on all leaves. No cob formation. Plants may be killed prematurely.

100.0

Susceptible

(Score: ≥ 4.0) (PDI: ≥ 80 .0)

*Percent disease index (PDI) 4. Curvularia leaf spot (CLS)

Mass multiplication of culture is done on half cooked sorghum grains and after evaporating excess moisture from surface, the grains are filled in 500 ml conical flasks and plugged properly. These are autoclaved for two hours at 15 lbs

pressure and inoculated when cooled down at room temperature with pure culture of Curvularia lunata. After completion of mycelial growth which may take 15-20

days at temperature around 25-27 degree C, these grains are washed in RO water to get conidial suspension of 5X104 conidia per ml. A bucket full of suspension is enough for spray inoculation of two 480 meter strip. The washed grains are spread

in a tray to get again mass of conidia. After two days gap, one more spray inoculation is done as per previous method, but this time conidial suspension should

be half of the previous one.

At least three observations are made and third observation at 80-85 DAS would be final based on leaf area covered by spots caused by pathogen.

Observations are recorded using 1-5 rating scale as described below:

Rating

5.0 81-100 % area of leaf infected

Susceptible

(Score: ≥ 4.0) (Severity: ≥ 80 .0)

5. Common rust (C. rust) and Polysora rust (P. rust)

The rust is an obligate parasite and thus, it is very difficult to grow it on artificial media under laboratory condition. Though, for some specific purposes

small amount of inoculum can be grown under laboratory condition on detached leaf culture. But, this meager amount of culture obtained by such method is not

sufficient to be utilized for large scale screening trials under field conditions. Therefore, naturally infected leaves showing large number of uredopustules may be collected from different places so that all the prevalent races in the areas may be

utilized for screening the materials against the prevalent rust fungus.

The infected leaves thus collected should be macerated thoroughly in

between two palms of the hands dipped under a bucket of water until the water gets sufficiently coloured. The uredospores can also be collected on a butter paper by tapping the severely infected leaves with fingers and then stored in glass vial or

glass tube which can be sealed easily under a flame. The uredospores, thus obtained may be kept for longer period in the freezer at lower temperature i.e.

5-7°C and can also be easily carried to some distant places for inoculation purposes.

For inoculating the plants in a field use of a knapsack sprayer is very useful.

The spore suspension should be sprayed over the plants during the second half of the day when the sun becomes mild. While spraying inoculum, the nozzle of the

sprayer should be kept over whorl of the plant and all the leaves may be sprayed thoroughly. The spore suspension must be stirred continuously during spraying as the light spores aggregate together on the upper surface of the water.

Repeating the inoculation two to three times gives a good result. In addition 2-4 lines of susceptible varieties grown as border rows around the screening plots

also help to spread the disease. Disease rating is done as per scale devised by Payak and Sharma# (1983).

6. Sorghum downy mildew(SDM)

Screening through direct inoculation with conidia:

Collection and maintenance of inoculum: Sorghum plants showing systemic infection of downy mildew from the farmer’s fields in and are collected during morning hours, preserved in polythene bags and brought to the laboratory. Conidiophores and conidia

from the white bloom found on the lower surface of the leaves are washed with a fine jet of distilled water and conidial suspension is collected from the sorghum leaves. The

seedlings of susceptible cultivar are spray inoculated at 2 leaf stage (6-7 days old) with the conidial suspension collected from the sorghum leaves. The inoculation of the

seedlings is continued till the plants reached 15 days and systemic symptoms are seen. The inoculum from these plants is multiplied by spray inoculating to the fortnightly sowings of maize. The infected plants are maintained in the plot

throughout the experimental period. Artificial inoculation technique developed by Lal and Singh (1984) is followed to induce the disease incidence by spraying conidial

suspension between 2.30 a.m. and 4.00 a.m. Evaluation of maize genotypes under artificial inoculation: Maize genotypes are

evaluated against sorghum downy mildew by artificial inoculation. Artificial

inoculation is done when the plants are at two leaves stage as described by Lal and Singh (1984). Diseased plants from which inoculum required to be drawn is

sprayed with water at 6.00 PM so that leaves would have a thin film of water for

79

good sporulation. By 2.00 AM, the inoculation crew assembles in the field with cleaned sprayers, torches and buckets. By 2.30 AM the diseased leaves with

good sporulation are searched and washed in the water at the rate of 15 leaves per litre of water collected in the buckets. This operation is completed by 3.00

AM. Then the collected spore suspension in different buckets is thoroughly mixed and made upto 25 litres. The 25 litres of conidial inoculum is collected from 375 diseased leaves. The inoculation is completed by 4.00 AM with hand

compression sprayer. Between 6.00 AM and at 6.00 PM water spray is given to the inoculated plot to create the required humidity artificially. With this method

100 percent disease incidence was created. Spreader row technique: Spreader rows are sown 15-20 days prior to the

sowing of the entries in 2.5 meter bands with a row spacing of 60 cm and plant

to plant spacing of 30 cm. each band consisting of four rows surrounding on all the four directions. For this, highly susceptible variety will be used. Inoculation

of these spreader rows is done by following the above artificial inoculation procedure. Test entries were sown as mentioned above.

Per cent disease incidence is recorded 35 days after sowing and the entries are

classified according to their disease reaction as described by Lal and Singh (1984).

Disease incidence (%) Disease reaction

≤ 10 Resistant

10.1 – 25.0 Moderately resistant

25.1 – 50.0 Moderately susceptible

≥ 50.0 Susceptible

7. Rajasthan Downy Mildew (RDM)

Downy mildew nurseryis required for artificial inoculation purposes.

Susceptible maize cultivar is grown in cage house and the plants are inoculated at seedling stage by placing bits of downy mildew infected grasses Heteropogoncontortus and H. melanocarpus. Humidity around 90% is maintained in

the cage house. Chlorotic symptoms along with light green color extends up to upper green portion are typical symptoms. During midnight hours a layer of conidia

can be seen. These plants serve as source of inoculum for artificial inoculation.

Since the pathogenis of nocturnal nature and produces conidia during 12:00 to 6 AM, hence the freshly harvested conidia are collected in distilled water or RO

water. Before collecting conidia the leaves can be washed before an hour so as to get fresh viable conidia. For screening the test entries, susceptible entries should be

planted before 15 days and should be inoculated first. Since this pathogen does not form oospores on maize, hence sick plot technique does not work. The conidial suspension of harvested conidia is filled in dropping bottle to put drops of inoculum

at seedling stage (6-7 days old) in the whorl (a cup like structure of upper leaf) during 3-5 AM. This should be done for 4-5 days regularly to avoid any escape.

After 15-20 days symptoms become visible.

The observation is recorded as percent infected plants in a row out of total plants. At least three observations are taken at 30, 50 and 80 DAS. The last

80

observation is considered as final, but number of plants is considered as of first observation. This is because some plants die and disappear due to infection. The

entries are classified according to their disease reaction as described by Lal and Singh (1984) for SDM.

8. Post flowering stalk rots (Charcoal rot, Fusarium stalk rot and Late wilt)

Screening for resistance against these diseases can is easily be donein sick plots. However, artificial inoculation is necessary where such plots are not available.

For this purpose the fungal material should be isolated from the infected stalks, cultured and multiplied in the laboratory as described below.

Small bits cut from the infected stalks should be surface sterilized with 0.1

per cent mercuric chloride solution for one minute followed by washing in sterile distilled water. Finally a single bit is to be aseptically transferred to sterilized potato

dextrose agar days at 26±2°C for getting the fungal hyphae to come out from the infected bits. Finally, the fungal hyphae is to be aseptically transferred to culture tubes containing the sterile PDA medium and to be incubated for about 10 days to

get the stock culture of the pathogen to be used for increase of the inoculum in the laboratory for field inoculation.

Among various methods of field inoculation, the toothpick inoculation is followed for these diseases under the co-ordinatedprogrammes. Round bamboo

toothpicks about 6.5 cm long are boiled three times (about 1 hour each time) in tap water to remove toxic substances. After each boiling these are thoroughly washed in fresh water and dried in the sun. When these are thoroughly dry, they are

loosely packed in bundles and put into the glass jars/ bottles and enough potato dextrose broth (one- third length of toothpicks) is added to thoroughly moisten the

toothpicks plus some quantity in the bottom of the jars. The jars with the toothpicks are autoclaved immediately after the broth is added. Later the sterilized toothpicks are inoculated with the culture of the pathogen aseptically. The growth

of the fungus covers the toothpicks and inoculum is ready for use in about 10 days.

Inoculations should be made just after flowering stage of plants. For

inoculating plants, the lower internode (second/third) above soil level is opened with a jabber and the toothpick is inserted into the hole. The jabber is made by driving a nail of the diameter of the toothpick into a wooden handle. The head of

the nail is ground off to a point and to the desired length (2cm). The round toothpicks effectively seal the hole in the stalk and prevent drying. The

measurement is based on the proportion of disease present in the inoculated internodes and its subsequent spread. For scoring disease severity of PFSR, 1-9 rating scale of Payak and Sharma# (1983) is followed:

Rating scale


1.0 Healthy or trace/slight discolouration at the site of inoculation.

9. Bacterial stalk rot (Pre-flowering stalk rot)

A virulent isolate of Erwinachrysanthemi corn pathotype should be selected for inoculation. To maintain the virulence of the bacterium, it should be inoculated on healthy plants and then reisolated every year before mass inoculation. In order to

isolate a virulent strain, the inoculated plants showing characteristic symptoms of the disease are selected. A small piece of rotten internode is immediately dipped

into mercuric chloride solution (1:1000) for 5 seconds and passed through three changes of sterile water. The piece is then cut into two halves with sterilized blade, put into little sterile water and then teased apart with sterile needle. The small

quantities of resulting suspension are then removed with a flamed wireloop and streaked out on well dried nutrient agar plates, the aim being to separate the cells

so that they produce individual colonies. The characteristic colonies are identified after 2 days of incubation at 30°C and used for subculturing. The culture is used for

testing the pathogenicity. The cultures which induce the typical symptoms of the disease within 48 hours of inoculation are used for mass inoculation. The inoculum is increased for mass inoculation on nutrient broth for 48 hours at 30°C. The

inoculum was diluted 10 times with sterile water to maintain a concentration of approximate 1X107-9 bacteria/ml.

The inoculation may be carried out when the crop is at the pre-silking stage or until flowering has reached 75%. To inoculate the plants a diagonal hole is made in the middle of second internode from the ground to the pith. One milliliter of

bacterial suspension is injected into the plant through the hole by a hypodermic syringe. If necessary, a second inoculation may be done one week later in the third

internode from the ground. Percent disease incidence is recorded 15 days after sowing and the entries are classified according to their disease reaction as described by Lal and Singh (1984) for SDM.

10. Maize cyst nematode (HeteroderaZeae)

Plant parasitic nematodes are responsible to causes 10.2% losses o maize.

Though, large number of plant parasitic nematodes attacks on maize but maize cyst nematode (Heteroderazeae) is considered as most important and therefore,

screeningtrials are carried out under artificially inoculated conditions in permanent plots to find out source of resistance against maize cyst nematode (Heteroderazeae). The observations on nematode infestation are recorded after 45 days of germination.

The varieties/hybrids/ lines are categorized on the basis of cyst/plant as mentioned below:

S. No. Number of cyst/plant Category

1 0 - 4 cyst/plant Resistant

2 Above 4 - 9 cyst/plant Moderately Resistant

3 Above 9 cyst/plant Susceptible

* Calculation of Percent Disease Index (PDI) of Foliar Diseases of Maize

Percent disease index (PDI) is calculated using the following formula of Mckinney

(1923).

Sum of individual rating 100

Percent disease index (PDI)= X No. of leaves examined Maximum disease rating

On the basis of PDI, the inbred lines/ varieties/ hybrids can be classified as resistant (R), moderately resistant (MR), moderately susceptible (MS) and

susceptible (S). The test inbred lines/ varieties/ hybrids with resistant reaction are considered acceptable for a breeding programme whereas test inbred lines/ varieties/ hybrids with moderately resistant are acceptable when lines with resistant

reaction are not available.
