Effect of environment on yield accumulation in wheat cultivars under Haryana conditions

A set of 42 genotypes of bread was grown in four different environments at the experimental area of Wheat and Barley Section, Department of Genetics and Plant breeding, CCS Haryana Agricultural University, Hisar during Rabi season of 2012–2013 to identify the suitable genotypes. Considerable genetic differences among genotypes for various traits were evident in all the four environments. From the mean performance of the genotypes based on all the four environments it appeared that genotypes WH 1105, WH 1142, WH 711, HD 2967, DBW 17, WH 542, PBW 343, DPW 621-50, PBW 550 and WH 1135 were promising for grain yield. Though grain yield production potential is the inherent property of a genotype, it is highly influenced by the environment.
