dc.description.abstractThe present study was carried out with the objectives of accessing the genetic variability, estimating the association between grain yield and its component traits and among themselves and finding out the stability of different genotypes. The material consisting of 42 diverse genotypes of bread wheat was grown in randomized block design with three replications in four environments created through manipulation of sowing dates during rabi season 2007-2008 at Hisar as well as Bawal locations. Significant differences were observed among genotypes for all the traits under all the four environments. Genotypes, WH 711, DBW 17, PBW343, UP2338, WH542, HD2687, PBW550 and WH416 have been found promising for grain yield in all the environments. However, genotypes, WH 1046, WH 1074, WH 1053, WH1070, WH 283, PBW550 were early in days to maturity in all the environments. The grain yield per plant showed positive and significant correlation with effective tillers per plant, number of grains per ear, 1000 grain weight and biological yield per plant however, it showed negative significant correlation with plant height in one or more environments. The path coefficient analysis revealed that biological yield per plant in the major contributor towards the grain yield per plant. The stability analysis indicated that both linear and non-linear components contributed to total GxE interaction for all the characters. Genotypes WH711, DBW17, PBW343, UP2338, HD2687, WH416 and WH283 were found stable for grain yield in all the different environments. It is suggested that these varieties can be used for developing desirable breeding material with better stability.en_US
