Combining ability for yield and different quality traits in rice (Oryza sativa L.)
Journal Title: Journal of Applied and Natural Science - Year 2016, Vol 8, Issue 4
Abstract
Gene action and combining ability for yields and quality traits were analyzed by line x tester analysis in 48 crosses along with 8 lines and 6 testers to find out their usefulness in improvement of quality traits. Analysis of variance revealed that ASD 16 line and Pusa Basmati 1 and Basmati 370 testers were the good combiners for both yield and quality traits. The crosses ADT 36 / GEB 24, ASD 16 / Pusa Basmati 1, ADT 43 / Jeeragasamba, MDU 2 / Pusa Basmati 1 and MDU 5 / Improved White Ponni were identified as the good specific combiners for grain yield and some other quality characters. Dominance gene action was found to be predominant for most of the quality characters along with yield giving way for exploitation of heterosis breeding for meeting out the increasing quality preference of the consumers.
