Other claims from this paper (14)
- Intervention effect New stress-tolerant maize hybrids had much better grain-yield performance than the best commercial checks under smallholder farmer growing environments.
- Intervention effect New stress-tolerant maize hybrids had comparable grain-yield performance under optimal conditions.
- Intervention effect These maize hybrids showed better grain-yield stability across the testing environments.
- Observation Farmers gave high importance to grain yield in both stated and revealed preferences for maize hybrids.
- Association The top-yielding hybrids in both maturity groups received the highest overall farmer scores.
- Observation Farmers ranked yield, early maturity and cob size as the most important traits for maize variety preference.
- Observation Farmers ranked number of cobs among the most important traits for maize variety preference.
- Association Farmer-stated importance of the criteria was quite different from farmer-revealed importance.
- Association The criteria for the different maize hybrids did not differ between men and women farmers.
- Association Men and women farmers differed significantly in the revealed importance of the selection criteria.
- Recommendation The authors recommend incorporating farmers’ selection criteria in the stage-gate advancement process of new maize hybrids.
- Recommendation The authors recommend increasing the turnover of new maize hybrids.
- Observation Hybrid performance differed between low-yielding and high-yielding maize environments.
- Observation Farmers gave priority to many traits in addition to grain yield, though this may not apply to all maize-growing regions.
