4. Resilience to an increasing riskEach “growing degree day” spent at a temperature above 30°C decreases yields by 1 percent under optimal (drought-free) rainfedconditions.

Southern Africa faces the risk of more severe and protracted droughts and periods of extremely low and extremely high rainfall could become more common as temperatures increase from 2-4°C

Curation and dissemination of TL-III Data as global public goods

• The Integrated Breeding Platform – Breeding Management System (BMS) was decided as a tool of choice for the management of TL III data

• 3 training sessions for BMS were conducted for project implementing staff in Nairobi, Addis Ababa and Bamako btw Aug and Dec 2015

• A BMS Cloud database for TL-III established.

Page 25: ESA crop improvement :  legumes

Salient Results cont

Communicating TL-III project progress, achievements and impact• Four volumes of the regular Quarterly Bulletin Tropical

legumes were produced highlighting specific aspects of project successes

• TL III web-page have been updated to include a TL III facebookand twitter links to communicate project information.

• A 182 page synthesis of the seven seasons of learning and engaging smallholder farmers through the tropical legumes in Sub-Saharan Africa and South Asia is ready for publication.

Salient Results cont

Management and reporting of TL-III Project• Launched TL III (August 17 – 22, 2015)• Worked with Country focal points and country teams to

develop Country Workplans• Worked with Objective leaders to synthesize these into Project

workplans (by objective)• Worked with ALINe Consultancy to develop Project MLE Plan• Visited project sites in all regions to monitor progress and

provide on the ground advice as needed

Page 27: ESA crop improvement :  legumes

Salient Results cont..

Supporting breeding pipelines for groundnuts, cowpea, common bean, and chickpea in target TL-III countries• TL III supported the implementation of the BPAT to all CGIAR

Africa based programs which included Program assessments for groundnut in Mali and Malawi, chickpea in Ethiopia, cowpea in Nigeria and common beans in Uganda and Malawi.

• Key findings - ICRISAT African based breeding programs have very competent scientists but are weak in breeding cycle time, phenotyping for drought, and application of marker assisted breeding technologies.

• These critical areas have been recommended for improvement as part of TL III improvement of breeding efficiency in African CGIAR sites and the target NARS.

Page 28: ESA crop improvement :  legumes

Challenges, Constraints & Mitigations

• It has taken long to fill the project positions – hence the project is off to a slow start (The gender scientist has not joined to-date and gender related research activities are behind schedule)

• Ongoing security and instability in parts of Mali and Nigeria

• Drought in Ethiopia (ElNino effect of 2015) .

Ascochyta blight; wilt-root rot complex of CP

• AB and WRR cause upto 100% loss

• No AB resistant desi variety

• Majority of farmers produce desi

• Planting late to avoid AB and FW

• Resistance varieties for early planting

• 3 new sources of double resistance identified

varieties• Maturity before terminal

drought

Page 33: ESA crop improvement :  legumes

Emerging issues: Early maturity

• Escape end-of-season drought and heat stresses

• short window of cropping season –double cropping

• enhance cropping resilience (intensification and diversification)

• Green pod chickpea market (challenges with human pest??)

• New sources from local and reference collections

Page 34: ESA crop improvement :  legumes

Nodulation/fixation may be limited by:• the presence ineffective strains • low population numbers, • low infectivity or lack of effectiveness, • poor survival rate of rhizobia in the soil• competition amongst strains of rhizobia• the absence of compatible strains (strain x

variety x environment interaction)

CRP-GL: Even lines earlier reported as non-nodulating do nodulate with compatible strainsTLIII: include basic N2Africa-recommended package of inoculum and agronomic practices in field demos.

From 50 indigenous rhizobia, 15 Rhizobia isolateswith wide pH tolerance, 5 with salinity tolerance,3 with high ToC tolerance, 5 with antibioticsresistance, 15 phosphate solubilizing isolates wereidentified.

The 50 isolates were further grown on yeast extractmannitol agar and single colonies cultured for molecularcharacterization.

43 isolates are currently being sequenced at UC-Davis

Implications for research• Differentiated genotypes

• Materials that can handle shading

• Agronomy• Plant population

management • Optimizing field architecture

Page 68: ESA crop improvement :  legumes

Output 2: Strengthening seed supply• 460 tons of foundation seeds

(groundnut, pigeonpea).

• 1,500 tons of groundnut certified seed.

• 280 tons of pigeonpea certified seed

Malawi:• 13 new community seed banks

identified for possible linkages to markets.

Tanzania• 6 new community seed banks

Uganda• 4 new communities engaged in seed

production

Strategy for scaling up and out

Page 70: ESA crop improvement :  legumes

Summary of 2014-2015Variety development 1. Advancement & evaluation of populations

2. New crosses made especially for output traits

3. Release in new countries: Zambia and Zimbabwe

4. Fundamental work: Resistance & genetic studies + integrated breeding

Technology promotion/ deployment 5. Scaling up and out- (Malawi, Mozambique, Uganda, Tanzania & Zambia)

6. Leverage intensification actions-Tanzania +Malawi+ Mozambique

Aflatoxins, nutrition and post harvest management

7. Aflatoxin & nutrition studies- Tanzania & Malawi + Zambia

8. Strengthen and deploy diagnostic tools and management options

9. Awareness (all CRP targets and leverage PACA efforts inSADC)

Complementary/leverage areas 10 New investments (leverage and engagement (HOPE, Harvest Plus)- Uganda, SMEAR-

Mozambique)
