Thirty hybrids were made from 13 parents in a line x tester mating design in order to ascertain combing ability during kharif 2012-13 and tested in a Randomized Block Design with two replications during kharif 2013-14. Analysis of variance for quantitative traits revealed that all accessions were significantly different and a wide range of variability exists for most of the traits studied. Most promising combinations for seed yield per plant were ICPA 2047 x ICPL 20126, ICPA 2048 x ICPL 20106, ICPA 2047 x ICPL 20108 and ICPA 2047 x ICPL 20098. The general combining ability revealed that among the testers, ICPL 20126 and ICPL 20108 were good general combiners for seed yield/plant. The results also revealed that some crosses exhibited high order significant and desirable SCA effects for different characters involved parents having different GCA effects.
