Estimation of heterosis in different crosses of bread wheat (Triticum aestivum L.)

Abstract: An experiment was conducted to estimate the nature and magnitude of heterosis for grain yield and its component traits using line × tester mating design (8 lines and 4 testers). The conspicuous heterotic effects were observed for grain yield per plant and its components. A total of 7 and 6 hybrids manifested significant desirable heterobeltiosis and standard heterosis, respectively for grain yield per plant. The heterobeltiosis for grain yield ranged from -46.25 to 51.74%, while standard heterosis ranged from -30.03 to 47.95%. The cross GW 11 × GW 451 (51.74%) exhibited the highest desirable heterosis over better parent followed by HD 2932 × GW 451 (33.24%) and HD 2932 × GW 496 (33.16%). The cross MP 3288 × GW 366 (47.95%) exhibited highest significant heterosis towards positive direction over standard check, followed by GW 11 × GW 451 (46.35%) and MP 3288 × HI 1544 (40.58%). Such crosses can be exploited for development of high yielding varieties.
