Combining ability analysis in Indian mustard [Brassica juncea (L.) Czern & Coss.] involving Ogura CMS system

Line × tester analysis was carried out to estimate combining ability of Ogura CMS based hybrids in Indian mustard [Brassica juncea (L.) Czern & Coss.]. For this, 50 hybrids were developed by crossing five Ogura CMS lines with ten restorers according to the Line x Tester mating design. A total of...

Czern & Coss.]. For this, 50 hybrids were developed by crossing five Ogura CMS lines with ten restorers according to the Line x Tester mating design. A total of 65 genotypes including 50 hybrids and 15 parents were evaluated during Rabi, 2017-18. Analysis of variance revealed significant differences among lines and crosses for most of the traits.

Line RH 0555-OA and tester IOR-12 were found to be good general combiners possessing highly significant and positive gca effects for seed yield and component traits. The cross RH 0630-OA × IOR-12 had expressed the highly significant and positive sca effects for seed yield per plant. Other crosses such as RH 8812-OA × IOR-3, RH 0749-OA × IOR-6, RH 0749-OA × IOR-22, RH 0749-OA × IOR-18 and RH 0630-OA × IOR-11 had exhibited significant sca effects for different yield related characters in Indian mustard.
