An investigation was taken up in soybean involving a set of five ovule parents (BRAGG, RKS 18, Co 2, Co (Soy) 3 and JS 335) and five pollen parents (LPA 5-1, LPA 5-2, LPA 5-3, LPA 13-1 and LPA 18) crossed in a line × tester mating fashion to study the general and specific combining ability and the gene action determining the yield component and biochemical traits. The lines are normal in phytic acid content. However, testers are low in phytic acid content. Twenty five crosses were made between these lines and testers in order to know the genetics of yield component and biochemical traits, during Kharif, 2013-14. Individual cross combinations along with their parents were studied for 13 characters during Rabi 2014. While comparing the performance of parents for per se and gca effects for low phytic acid content and yield components Co (Soy) 3 and LPA 5-2 were considered as superior parents for breeding programme. The crosses RKS 18 × LPA 5-2, Co (Soy) 3 × LPA 5-2 and Co (Soy) 3 × LPA 5-1, Co (Soy) 3 × LPA 13-1 exhibited superior per se performance and one of the parent possessed good general combining ability for yield component and biochemical traits which indicates additive type of gene action.
