Association Studies in the Three Segregating Populations of Cowpea (Vigna unguiculata (L.) Walp.)

Suma Biradar, P.M. Salimath, O. Sridevi

Abstract


The present study was aimed at investigating the potentiality of a germplasm accession Goa local (GL) with exceptionally high seed weight and also diverse from three agronomic backgrounds viz., KM-1, C-152 and V-118 with respect to many other traits. Analysis of covariance indicated that the trait of interest yield is positively and significantly associated with its contributing morphological characters. Highest yield was realized through pod number and indirectly by branch number. Among the three F2 segregating populations, KM-1 x Goa local can be exploited for simultaneous improvement of pod traits viz., number of pods, seeds per pod and seed weight.
