Abstract:
The investigation was laid out in RBD with three replication during kharif- 2016 at the Horticulture research farm, Department of Horticulture SHUATS, Allahabad. The correlation coefficient at genotypic level is higher than corresponding phenotypic level, indicating that there is a strong association between these traits and pod yield genetically. Pod yield/plant showed significant and positive correlation with plant height 45 days, number of pods/plant and days to 50% flowering at both phenotypic and genotypic level. Seed yield/plant (g) showed non-significant and positive correlation with fruit cluster/plant, pod/cluster and 100 seed weight at both phenotypic and genotypic level. The path coefficient analysis which splits total correlated coefficient of different characters into direct and indirect effects on pod and seed yield per plant in such a manner that the sum of direct and indirect effects is equal to total genotypic correlated. Pods/plant had positive direct effect on pod yield/plant. Fruit clusters/plant had direct negative effect on seed yield/plant. Seeds/pod had direct negative effect on seed yield/plant.
