What is an important food crop in India but of the entire world. The study indicates that the analysis of the variance showed highly significant differences for all the characters. Genetic variability indicated that high estimates of GCV and PCV were observed for the traits like 1000 grain weight, grains per spike, spikelets per spike, spike length and yield per plot. Further, high heritability coupled with high genetic advance as percent of mean was also observed, indicating the less influence of environmental variance in these characters. Correlation study revealed that plot yield had strong positive association with 1000 grain weight, spike length, spikelet‟s per spike. The results seed yield and on CTD and chlorophyll content have strong association indicating that these characters are helpful for selection for heat tolerance wheat genotypes. | Studies on genetic variability heritability genetic advances and association of morpho-physiological traits and their relation with heat tolerance in wheat
