Farmers opinions through visual ratingare systematicallycollectedandused
n selection decision throughpreference analysis (PA) in researcher-managed
trials. Below is the PA protocol.
Farmers selection of released or pre-
released advanced lines and local varieties
tested on-station and in farmers fields.
A simple way for breeders and
agronomists to learn which rice
varieties perform well on-station
and on-farm and to obtain feedback
from potential end users in the
early phase of the breeding cycle.
A means for social scientists and
breeders to identify the specific
traits that farmers look for in rice
varieties suitable for their specific
environments and livelihood.
Main purpose of PVS
~ PVS includes researcher-managed (R-M) trials or mother trials, farmer-managed
(F-M) trials or baby trials, and sensory evaluation of farmer-preferred lines/varieties.
At least 30% of the participants should be women farmers.
IRRI emphasizes the importance ofPVSprotocols in rice breeding programs.
Sensory evaluation
is a useful process in evaluatingthe cooking and eating quality of
the top two preferred lines
tolerant to specific stress
(i.e., submergence, salinity,
sodicity, drought), tested in R-M
trials plus the farmers local
variety. The evaluation may be
conducted one month after
harvesting. This evaluation could
help confirm whether the
lines/varieties selected by
farmers through visual rating
before harvest are acceptable interms of eating and cooking
qualities and their cultural needs.
To enhance the capacity ofNARES partners in
PVS in various research projects, a number of
training courses were given in-country and at IRRI .
Farmer-managed trials/baby trialsines/varieties selected from preference analysis
on researcher-managed trials are tested by farmers
n their own fields using their resources and level of
management. Farmers ratings, comments, and
yield reports of preferred varieties are the main
outputs of baby trials and are compared with
heir own previously grown varieties.Men and women have common and different varietal preferences based on
gender roles. Therefore their opinions should be considered in varietal improvem
This mother-baby trials approach in plant breeding is found to be an effective strategy in
developing and disseminating improved crop varieties in stressed environments by many
international agricultural research centers (IARCs) under the Consultative Group on
International Agricultural Research (CGIAR). ~ Bellon and Reeves, 2002
Data from PVS should be considered in the varietal release system to speed updelivery and acceptance of new varieties by farmers on a large scale.

How to ensure that men and women farmers opinions matter:
Collect information on rice varieties, the reasons for farmer
adoption/disadoption, and preferred traits of rice varieties.
Involve men and women in selecting the best lines included in R-M
trials and listen to their reasons for selection.
Involve men and women in evaluating the eating,
cooking, and postharvest qualities of two best lines.
Consider men and womens feedback on the lines/
varieties that they tested in their own fields.
Enhance the capacity of partners
(scientists and farmers).
