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.
