Section 7 • Participatory Plant Breeding, Seed Production, Harvest, and Post-Harvest Management
5 Pest and diseases incidence (e.g., major pests and diseases)
5 Size and shape of pods or fruits (e.g., maturity index of crop)
5 Other fruit or pod characters (e.g., texture, cracking, firmness, shelf life, acceptability)
2. Go back to processing area; brainstorm in small groups and present output to the big group.
Conduct participatory discussions to allow sharing of experiences among participants and
facilitators.
3. Motivate farmers to share their best experiences in seed/variety selection and seed production
of self-pollinated vegetable crops (e.g., legumes, and solanaceous crops) in their own farms,
especially on the following:
5 Selection of species or varieties for seed production;
5 Important plant and fruit characters
5 Isolation distance between crop varieties;
5 Regular field inspection and roguing; and
5 Harvesting at most mature stage of seed.
4. Facilitate each small group to do hands-on of best experiences in seed selection and seed
production in a portion of some self-pollinated vegetable crops (e.g., legumes, and solanaceous
crops) grown in learning field, as follows:
5 Determine area needed for farmer’s seed requirement (e.g., know farmer’s seed requirement
per hectare, his normal yield level per cropping, and his estimated production per unit area).
5 Measure and mark boundaries in a portion of some self-pollinated vegetable crops (e.g.,
legumes, and solanaceous crops) grown in learning field (e.g., using above estimated area).
5 Conduct regular inspection and roguing (e.g., regular removal of other cultivars, weeds, offtypes,
deformed or disease and pest affected plants and other plants whose characteristics
do not conform with desired cultivar at early vegetative, flowering, fruiting and harvesting
stages).
5 Employ other cultural management practices shared and agreed upon in a big group
brainstorming session.
5 Take note of all relevant observations and experiences during this activity.
5. Synthesize and summarize output of small groups into one big group output. Draw up
conclusions and recommendations from this exercise.
