Laboratory experiments to screen wheat genotypes for high temperature tolerance at germination and seedling vigour index indicated a large variation among genotypes in respect of germination, root and shoot development. The germination progressively and significantly decreased with increase in temperature from 25 to 35°C. Shoot length gave a differential response to higher temperature, seedling vigour index obtained by multiplication of root length with germination per cent gives vigour index of seedling underhigh temperature.
