Abstract

In the present study six diverse genotypes (exotic and indigenous) of cowpea were
crossed in diallel fashion excluding reciprocals. Six parents and their 15 F1 were raised
in randomized block design with three replications during kharif, 2007 (E1) and summer,
2008 (E2) The best specific combiner for seed yield per plant was IT-97K-1042 X IT-98K-
1111 and IT-98K-205 X Pusa Komal. This cross combination emanated from parents
involving good X good and good X average gca effects. Pooled analysis of variance for
combining ability showed significant interaction of gca variances and sca variances with
environments except for virus and insect incidence indicating the role of environment
in influencing the gene effects.
