Abstract:
An experiment was conducted with eleven genotypes in the rabi season of 2017-18 at research and education farm, Department of Agriculture Botany, College of Agriculture, Dapoli. Observations were recorded on twelve characters viz., days to initiation of flowering, day to 50 percent flowering, days to first pod picking, plant height (cm), number of primary branches per plant, number of clusters per plant, number of pods per cluster, number of pods per plant, pod length (cm), green pod weight per plant (g), harvest index (%) and protein content (%). The correlation study revealed that the characters viz., plant height, number of primary branches per plant, number of clusters per plant, number of pods per cluster, number of pods per plant and pod length had a highly significant positive correlation with green pod weight per plant (g) at both phenotypic and genotypic level. The path coefficient analysis revealed a positive direct effect of characters viz., plant height, number of clusters per plant, number of pods per cluster, number of pods per plant, pod length and harvest index on green pod weight per plant at both genotypic and phenotypic level while, days to initiation of flowering and days to 50% percent flowering at phenotypic and genotypic level respectively. Based on association analysis studies, it can be concluded that the selection criteria based on plant height, number of clusters per plant, number of pods per plant and pod length can provide a better result for improvement of green pod weight per plant in cowpea under study.
