Other claims from this paper (11)
- Observation Location, genotype and genotype by environment interaction differed significantly for grain yield, days to anthesis, anthesis-silking interval and ear aspect under nonstress conditions.
- Observation Top 20 DH maize hybrids yielded 8.15-8.85 t/ha under optimum management.
- Observation Top 20 DH maize hybrids yielded 4.53-5.67 t/ha under drought stress.
- Observation The best commercial maize variety yielded 7.67 t/ha under optimum conditions.
- Observation The best commercial maize variety yielded 3.43 t/ha under drought stress.
- Intervention effect Top ten DH maize testcross hybrids yielded 16% more than the best commercial check across four optimum locations.
- Intervention effect Top ten DH maize hybrids produced 62% higher grain yield than the best commercial check under managed drought.
- Observation DH maize testcross entries 23, 28 and 71 had high grain yield under both stress and non-stress conditions.
- Observation DH maize testcross entries 23, 28 and 71 had high stress tolerance indices.
- Observation DH maize testcross entries 23, 28 and 71 had low stress susceptibility indices.
- Recommendation The identified DH maize lines are proposed for improving grain yields in drought-prone mid-altitude areas of eastern and southern Africa.
