Abstract

A 6 x 6 half dialIeI study in barley was performed for yield and other quantitative traits. The gca and sea components were highly significant for all the traits of the study. For the traits viz., grain yield, plant height, ear length, tillers per plant, spikelets per ear and grains per ear, the gca component of variance was higher than the sea component indicating preponderance of additive gene effect. The parent RD 31 was good general combiner for grain yield per plant, ear length, tillers per plant, spikelets per ear and grains per ear. The crosses RD 103 x BL 2, RD 2052 x RD 103 and RD 2052 x RD 2433 were the best specific cross combinations for most of the traits under study.
