The present study was conducted to work out combining ability and heterosis studies using Line × Tester mating design in rice using 12 lines suitable for upland conditions of H.P. and 3 testers in Kharif 2019 and 2020 (for crossing and evaluation, respectively). Significant GCA and SCA effects were found for the lines and crosses, respectively. The lines showing significant GCA effects were HPR 2884, HPR 2871, HPR 2873 and HPR 2889, while the crosses HPR 2866 x HPR 2656, HPR 2866 x HPR 1156 and HPR 2840 x HPR 1156 showed high SCA for most of the traits. The cross combinations that showed significantly high heterosis over the standard check for grain yield per plant were HPR 2866 x HPR 1156 (68.82%), HPR 2840 x HPR 1156 (58.37%), HPR 2840 x HPR 2795 (57.82%) and HPR 2873 x HPR 2795 (40.64%).

Abstract


The present study was conducted to work out combining ability and heterosis studies using Line × Tester mating design in rice using 12 lines suitable for upland conditions of H.P. and 3 testers in Kharif 2019 and 2020 (for crossing and evaluation, respectively). Significant GCA and SCA effects were found for the lines and crosses, respectively. The lines showing significant GCA effects were HPR 2884, HPR 2871, HPR 2873 and HPR 2889, while the crosses HPR 2866 x HPR 2656, HPR 2866 x HPR 1156 and HPR 2840 x HPR 1156 showed high SCA for most of the traits. The cross combinations that showed significantly high heterosis over the standard check for grain yield per plant were HPR 2866 x HPR 1156 (68.82%), HPR 2840 x HPR 1156 (58.37%), HPR 2840 x HPR 2795 (57.82%) and HPR 2873 x HPR 2795 (40.64%).
