Abstract:
The present experiment conducted with twelve genotypes of wheat by using Eberhart and Russell (1966) model for days to 50% heading, days to maturity (days), plant height (cm), spike length (cm), spikelets per spike, effective tillers per plant, grains per spike, 1000 grain weight (g), grain yield per hectare (q), biological yield per hectare (q) and harvest index in three date of sowing during Rabi- 2019-20 viz. 8th Nov. (normal sown), 4th Dec. (late sown) and 24th 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 all the characters under study. Differences due to Genotype × Environment were also found highly significant for all the study traits, indicates that genotypes interacted considerably to environmental conditions in different environments. 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.
