Combining Ability Analysis for Yield and Yield Components in Rice (Oryza sativa L.)

Presence of sufficient variation among the genotypes was evident from the analysis of variance. Prevalence of additive as well as non- additive gene action was indicated, for all the characters, by the analysis of variance for combining ability. Bahadur and Teke were found to be the best general combiners with respect to grain yield per plant. These two parents were good general combiners for atleast four other desirable traits also. In the present study good x good combiners like Teke x Bahadur and Teke x Ranjit and good x poor combiners like Malong x Bahadur, Mehuru x Ranjit, Mehuru x Bahadur and Teke x Piolee were among the best specific combiners.
