Author Contribution : Harsh.V.S.Shekhawat- Ph.D scholar in the Plant breeding and Genetics department provided F1 seeds for carrying out this study

The combining ability studies involving 50 hybrids generated through Line x Tester mating of 10 lines and 5 testers was conducted at SKRAU, Bikaner.The combining ability analysis of 15 parents and their 50 F1s revealed the presence of significance differences for general combining ability for all the characters. GCA and SCA variances significant for days to maturity, plant height, number of primary branches per plant and seed yield per plant. The parents RGN-298, RGN-303, RGN-236, were found to be good general combiner for seed yield and some other contributing characters. The cross combination RGN-298 x Kranti showed high per se performance as well high SCA effects for seed yield and yield contributing characters
