Genetic analysis of combining ability for quality characters in Basmati rice

Based on the general combining ability estimates for 11 grain quality characters in a set of crosses involving nine parents of indica rice. It was observed that none of parental line was found excellent for all the 11 qualitative characters. Among the nine lines, three lines viz., Pusa-1121(L7), Pusa 1463(L9) and Pusa-1176(L6) showed good general combining ability effect of maximum quality characters. Among all the crosses, P-1463 x P-44 showed high specific combining ability effects as well as high heterosis. P-1173 x Heibao, Shah-Pasand x P-44 and Bas-370 x Heibao were good specific combiner for different characters. These crosses can be used for development of hybrid in future.
