ABSTRACT
The combining ability of five mate sterile lines of pearl millet in crosses with eight diverse genotypes was studied in Line x Tester fashion for Leaves/main shoot, flag leaf area, grains/sq. cm. area of main ear, 1000 grain weight, fodder yield (dry) and harvest index. The involvement of additive gene action was observed for leaves/main shootand grains/sq. ern. area of main ear. The non-additive gene action was observed for flag leaf area, 1000 grain weight, fodder yield and harvest index. However, study of sea effects revealed that the combinations of High x High, High x Low and Low x Low were involved in the expression of these traits indicating the preponderance of both additive and non-additive gene action. The female parent MS 88628 A and MS 88840 A and mate parents 88839 and 884582 were found to be the best general combiners fot maximum traits. The improvement of fodder yield and other component characters can be obtained by resorting to more efficient breeding methodologies such as recurrent selection and biparental mating rather than conventional methods.
