Combining ability for yield and different quality traits in rice

摘要

Combining ability studies in rice for kernel quality traits revealed non-additive gene action for all the characters. Based on per se performance and gca effects, ADT-38, Improved White Ponni, Pusa Basmati 1 and Taraori Basmati were the best parentsfor improvement of quality traits besides grain yield. ADT-38/Pusa Basmati 1 and Improved White Ponni/Pusa Basmati 1 were suitable for recombination breeding, while Improved White Ponnl / Taraori Basmati and Improved White Ponni / Pusa Basmati 1 may be exploited for heterosis breeding.
