Abstract:
The present study was carried out with 20 hybrids generated by hybridizing five lines and four testers in a Line x Tester mating fashion to assess the combining ability of five lines and four testers for pod yield and stem rot incidence. Substantial genetic variability was observed among the hybrids due to diverse nature of lines and testers for the two traits studied. The analysis revealed that among parents, Kadiri-6 and ICGV-07262 are identified as good general combiners for both the traits indicating that these parents could be used in breeding programme for development of high pod yield and stem rot resistant genotypes. Among F1 crosses, Narayani x J-11, ICGV-07262 x TCGS- 1862, ICGV-07262 x TCGS-2149 and ICGV-91114 x TCGS-2149 were considered as good specific combiners for both the traits suggesting that these crosses would be utilized for further selection to develop high yielding segregants with stem rot resistance in the segregating populations.
