Abstract:

Genetic variability, heritability, correlation and path analysis were estimated among 59 accessions of 08 quantitative characters in durum wheat. The highest value of GCV and PCV were observed for grain yield per plot, tillers per meter row length, spike length, grains per spike and test grain weight. It is also observed that the traits like grain yield per plot, tillers per meter row length, grains per spike and test grain weight exhibited high GCV also possesses high genetic gain indicating preponderance of additive gene effect for these traits. In corollary to high heritability, estimates of genetic advance as per cent of mean was also observed for indicating predominance of additive gene effects for these traits. In the present investigation grain yield was positively and significantly correlated with plant height, grains per spike and spike length. The path coefficient analysis revealed that grains per spike had maximum positive direct effect on grain yield followed by spike length and plant height. Therefore, greater emphasis should be given on these characters while selecting for higher yield and related traits.
