Abstract

In cowpea, dual purpose plant types are more preferable for cultivation. Therefore, exotic and indigenous cowpea germplasm lines were evaluated in augmented design to study estimates of the correlation coefficients and path analysis of morphological as well as fodder and grain yield attributes. The present study showed a high impact of direct effects of correlation (0.9714**) and suggested that going for plant types with higher biomass per plant (0.8856**), dry weight per plant (0.4598), stem girth (0.2336) number of secondary branches (0.2788), leaves per plant (0.3251), pods per plant (0.9059) and pod clusters per plant (0.7718) would be effective for improving both fodder and seed yield in cowpea.
