Abstract:
An experiment was conducted with forty one genotypes in rabi season of 2019-20 at research and education farm, Department of Agriculture Botany, College of Agriculture, Dapoli. Observations were recorded on eleven characters viz., days to initiation of flowering, day to 50 per cent flowering, days to maturity, plant height at maturity (cm), number of primary branches per plant, number of pods per plant, number of seeds per pod, 100 seed weight, pod length (cm), dry matter yield per plant, harvest index (%), seed yield per plant, protein content (%) and iron content (ppm). The correlation study revealed that the characters viz., dry matter yield per plant and harvest index showed highly significant positive correlation with grain yield per plant at phenotypic and genotypic level. The path coefficient analysis revealed that the characters viz., days to fifty percent flowering, number of pods per plant, number of seeds per pod, plant height at maturity, dry matter yield per plant and harvest index exhibited positive direct effect on seed yield per plant. On the basis of path analysis and correlation study for grain yield, it is concluded that selection on the basis of days to initiation of flowering, number of primary branches per plant, pods per plant and hundred seeds weight could help in genetic improvement of grain yield per plant in cowpea under study.
