The effect of post-anthesis high temperature on seed quality was studied in four promising genotypes (T 2003R, R 902, R 958 and R 965) of wheat (Trirticum aestivum L.) under a controlled environment (30°/25°C day/night temperature from 81 days after sowing to harvest matu­rity). Seed mass, density, seed membrane development, ability to germinate, subsequent seed longevity and seedling vigour declined in the seeds harvested from high temperature after post-anthesis, resulting in early maturation and poor desiccation tolerance at harvest maturity. Genotype R 965 showed greater resilience to damage compared to the other genotypes
