Effect of Heat Stress on Grain Weight in Bread Wheat

Prakriti Khajuria, Anil K Singh, Ravinder Singh

Abstract :

Heat stress affects a number of physiological and morphological traits in crops. The present study was undertaken to determine the effect of terminal heat stress on a set of 95 ead wheat genotypes. The wheat genotypes were evaluated under normal and late sowing conditions in two different locations. Analysis of variance revealed that location, sowing time and genotype has marked effect on thousand grain weight. Heat Susceptibility Index (HSI) was measured to identify 24 genotypes as highly heat tolerant (HSI<0.5) in one location and 33 genotypes in other location. Ten genotypes were found to be common between groups of genotypes heat tolerant in two locations. The genotypes identified as heat tolerant would form an important resource for the development of high–yielding varieties under heat stress.
