ABSTRACT
Twelve cross combinations of cowpea were used to analyse the parent -progeny regression between F3 and F4 generation for seed yield. Four cross combinations showed positive and significant parent -progeny regression coefficient which indicated that phenotypic selection for seed yield in one generation may lead to good positive response in the next generation. The selected four cross combinations in F4 generation were used to study the genetic variability and heritability for five traits viz., plant height, number of branches per plant, pod length, number of pods per plant and seed yield per plant. The genotypic co-efficient of variations and phenotypic co-efficient of variations were moderate for plant height, pod length and seed yield per plant. The difference between GCV and PCV were meagre for all traits in all the four cross combinations. Heritability values for all the traits were high in most of the cross combinations. High heritability accompanied with high genetic advance was observed for plant height, number of branches per plant, pod length and seed yield per plant in most of the cross combinations. The characters branches perplant ami seed yield per plant in all the F4 cross combinations would deserve greater weightage while selecting cowpea genotypes.
