Abstract
This study carried out at Genetics and Plant Breeding on the research farm of BNPG Collage Rath, Hamirpur (UP) keeping in mind for selection of parents and their hybrid combinations per se performance, GCA effects, and involvement of desirable specific combinations which give the idea about the potentiality of the parents. The best per se performance in 11 out of 12 cases showed best general combiner in both the generations. The best common parents on the basis of per se performance and significant ( general combining ability) gca effects in both the generations were CSR 1020, CSR 1014, CSR 1102 and CSR 1104 for days to flowering, CSR 1102 for number of primary branches per plant CSR 1025, CSR 1118 and CSR 1102 for number of secondary branches per plant; CSR 1025 and CSR 1020 for number of siliquae per main shoot; CSR 1066, CSR 1020, CSR 1118 and CSR 1027 for number of seeds per siliqua; CSR 1066 and CSR 1020 for siliquae length; CSR 1020 for biological yield; CSR 1088, CSR 1082 and CSR 1020, CSR 1014 and CSR 1088 for 1000-seed weight; CSR 1027, CSR 1088 and CSR 1118 for oil content and CSR 1020 for seed yield per plant
