Line x Tester Analysis in Local Ecotypes of Pearl Millet [Pennisetum typhoides ( BURM.) S & h] of Sikar District of Rajasthan for Quality Attributes

Abstract

A line x tester analysis with 143 lines (S₁ progenies) developed from local ecotypes collected from Sikar district of Rajasthan and 5 testers of fodder pearl millet revealed that differences between the progenies were significant for all the quality characters studied. Combining ability analysis indicated that variances due to GCA were non-significant while the variances due to SCA were significant for all the qualitative traits studied, indicating preponderance of non-additive gene action in the control of the inheritance of the quality traits. Comparison on the basis of GCA effects indicated that lines 62 and 131 are the desirable ones for most of the quality traits studied. The crosses exhibiting desirable SCAeffects had testers whichdid not have desirable GCA effects for the quality traits.
