Abstract

Combining ability in rice was studied with a set of 4 lines and 10 testers and their 40 hybrids. The magnitudes of gea variances were higher than sea variances for all the characters which indicated that additive gene action was predominant in the expression of traits. The estimation of gea effects for parents revealed that females, Acharmati, Pusa Sugandha-5 and males IET-1934 7, GR-4 and GNR-2 were good general combiners for yield and yield contributing characters. The best specific cross combinations obtained through poor x good and poor x average combining parents respectively for grain yield per plant.
