The study was conducted to examine the effect of high temperature on seed quality attributes viz., physical, physiological and biochemical in wheat. Twelve diverse genotype’s seed obtained from normal and high temperature growing conditions were tested for quality. High parent plant growth temperature during seed development and maturation resulted in poor seed quality. The effect of parent plant growth temperature on seed germination and emergence was inconsistent among wheat genotypes. Seed vigor as indicated by seed density, conductivity of seed leachates, seedling dry weight and production of normal seedlings, were reduced in all wheat genotypes due to higher parent plant growth temperature but heat-sensitive wheat genotypes were affected more than the heat-tolerant genotypes. Further, total hydrogen peroxide activity was increased and total antioxidant capacity decreased in genotypes obtained from high growth temperature.
