ABSTRACT
Combining ability analysis is a powerful tool to identify the parents. It also elucidates the nature of gene action involved in the inheritance of the characters. The present study involving 45 hybrids between three genetic male sterile lines (MSCo5,MSC11 and MS3783) and 15 testers of medium duration pigeonpea was conducted at three locations (Sardarkrushinagar, Khedbramha and Bharuch).Male sterile line MSCo5 was found to be good general combiner for branches/plant, pods/plant and grain yield. The male parents viz., ICPL 84060, BSMR 853, P175, P185,P318 and P3760 were found to be good general combiners for yield and one or more component traits. Sixteen out of 45 hybrids showed significant positive sca effects for seed yield and its one or more component traits. The sca effects revealed that MS3783 x BSMR 853, MSCo5 x P 185 and MSC11 x WRG 9701 were top three experimental hybrids which may be exploited for commercial utilization.
