High-yielding cowpea genotypes identified through genetic variability analysis.
The study looked at different cowpea genotypes to see how they vary in traits like plant height, number of pods per plant, and seed yield. They found that some genotypes showed significant differences in these traits. Traits like number of pods per plant, harvest index, and plant height had high variability and genetic gain. Plant height, number of pods per plant, harvest index, and number of seeds per pod were strongly linked to seed yield. This means that these traits directly contribute to how much seed a cowpea plant produces.
