To ascertain combining ability 24 hybrids were made from 10 parents in a line × testes mating design, during kharif 2023 and tested in a Randomized Block Design with two Replication during kharif 2024. Analysis of variance for quantitative traits, revealed that all characters were significantly different and a wide range of variability exists for most of the traits studied. The hybrids BDN2004-1A × BDNHR 31-25-1, BDN2004-3A × BDNHR-250157, BDN2004-1A × BDNHR 31-14-2 and BSMR 736A × BDNHR 24-1-1. were good specific combiners for seed yield/plant and BDN2013-41A× BDNHR24-1-1, BSMR736 × BDNHR24-1-1for50percent flowering, BSMR736A× BDNHR 250157, BSMR736A×BDNHR-36-1-1, BDN2004-1A ×BDNHR31-25-1 for days to maturity, BSMR736A× BDNHR31-25-1, BDN2004-1 BDNHR250157 for plant height, BDN2004-1A× BDNHR250157, BDN2004-1A× BDNHR24-1-1 for number of primary branches, BDN2004-× BDNHR24-1-1, BSMR736A× BDNHR-250157 for number of secondary branches, BDN2004-1A × BDNHR36-1-1, BDN2004-1A× BDNHR31-14-2 for number of pods/plant. The results also revealed that some crosses exihibited high order significant & desirable SCA effects for different characters involved parentsBDNHR24-1-1, BDNHR-250157, BDN2004-3A, BDN2013-41A for 50 per flowering, BDNHR36-1-1, BDNHR-250157for days to maturity, BSMR736A, BDNHR 31-25-1 for number of primary branches, BDN2004-1A, BDNHR24-1-1 for number of secondary branches, BDN2004-3A for number of pods/plant, BSMR736, BDNHR-250157 for number of seeds/plant, BDN2004-3A, BDNHR 24-1-1for 100 seed weight, BDN2004-1A, BDNHR 24-1-1 for seed yeild having GCA effect.
