Twenty tomato genotypes were evaluated for heat tolerance by comparing six heat influenced traits under normal and elevated temperature regime. Stigma exersion, reduction in pollen fertility, increased flower drop, decreased fruit numbers, fruit weight and fruit yield were observed under high temperature in all the genotypes. However, the yield loss due to high temperature was comparatively lesser in genotypes LP-1, CLN2001A, BL1174, CLN2366A and CLN2413R.
