Abstract:
The experiment conducted with 12 genotypes of bread wheat by using Eberhart and Russell (1966) model for grain yield under different environment during Rabi- 2019-20 viz. 8^th Nov. (normal sown), 4^th Dec. (late sown) and 24^th Dec. (very late sown) at All India Co-ordinated Wheat & Barley Improvement Project, B.T.C. College of Agriculture and Research Station, Bilaspur, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh. The variances due to genotypes was found significant revealed the presence of genetic variability for grain yield. The genotype Ratan and CG-1029 was stable for all the characters. This is revealing not only the amount of variability that existed among environments but also the presence of genetic variation among the genotypes. Only the genotype CG-1029 having high mean performance, non-significant regression coefficient deviation from unity (bi=1) and non-significant deviation from zero (S²d=0) in term of grain yield per hectare. Hence, in term of grain yield per hectare CG-1029 can be considered the most stable and adopted to all environments compared to other stable genotypes.
