ABSTRACT

Twenty-eight cowpea crosses derived from crossing in a diallel mating design along with
their eight parents were evaluated for 10 yield and yield component characters to estimate
heterosis. Heterosis was observed for all the characters studied. Four crosses, GC-0011 x GC-
9710, CAZC-21 x DCP-2, GC-9710 x DCP-2 and GC-108 x DCP-2 recorded significant positive
heterosis over mid and better-parents for seed yield per plant. It is primarily due to complementary
combination of component traits viz., branches per plant, seeds per pod and 100 seed weight.
Positive heterosis over better parent was recorded for protein content in the cross GC-9710 x
CAZC-21. These heterotic cross combinations could be exploited to get superior segregants.
