TAILIEUCHUNG - Heterosis for grain yield and yield components in bread wheat (Triticum aestivum L.) over environments

Ten parents along with forty-five hybrids (developed by half-diallel) and one check (Lok 1) were evaluated in randomized block design with three replications in three environments [early sowing (E1), normal sowing (E2) and late sowing (E3)] during rabi 2016-17. The significant and positive heterobeltiosis was recorded for grain yield per plant by seven crosses in E1; nine crosses in E2; and six crosses in E3, while 31 crosses in E1; 19 crosses in E2; and 38 crosses in E3 exhibited significant and positive standard heterosis. In general, magnitude of heterosis over better parent and standard check for grain yield per plant was medium and high, respectively. Comparison of crosses on the basis of per se performance, heterosis over better parent and standard check for grain yield per plant revealed that five crosses viz., GW 463 x DBW 110, GW 455 x MP 3288, GW 455 x MP 3288, GW 273 x Raj 4238 and GW 451 x HD 2932 manifested significant and desirable heterobeltiosis and standard heterosis in all the three environments (except GW 455 x MP 3288 for heterobeltiosis in E3). | Heterosis for grain yield and yield components in bread wheat (Triticum aestivum L.) over environments
