Exploration of combining ability for yield and morpholo-physical traits in hybrid rice (Oryza sativa L.)

Author(s):

Madhru Grace Minz and Deepak Sharma

Abstract:
Combining ability in rice was studied with a set of 4 line and 10 testers and their 40 hybrids. The magnitudes of GCA variances were higher than SCA variance for all the characters which indicated the additive gene action was predominant in the expression of traits. The estimation of GCA effects for parents revealed that females, APMS 6A & males OM6162 & CBO5-501 were good general combiners for yield & yield attributing characters. The best specific cross combinations obtained through poor X good & Poor average combining parents respectively for grain yield per plant
