Abstract:

Inter relationship among yield and its attributes in cowpea can be studied through correlation and path analysis. In the current study, 102 Indian cowpea genotypes were evaluated based on twelve quantitative characters to study the association between yield and its contributing traits. Single plant yield showed significant positive correlation with traits viz., number of clusters per plant, number of pods per plant, pod length, number of seeds per pod, number of pods per cluster and hundred seed weight. The highest inter correlation was obtained between number of clusters per plant and number of pods per plant. Path analysis revealed that, the highest direct effect on single plant yield was obtained by number of pods per plant and it is followed by hundred seed weight and number of seeds per pod. The highest positive indirect effect on single plant yield was observed in number of clusters per plant through number of pods per plant. Hence, selection based on the traits viz., number of clusters per plant, number of pods per plant, number of seeds per pod, hundred seed weight and pod length will be highly rewarding in cowpea yield improvement program.
