Fifty-two genotypes of cotton belonging to Gossypium hirsutum, G. herbaceum and G. arboreum were screened for drought tolerance using line source sprinkler irrigation technique. The relative drought tolerance was tested by regressing the biomass yields and seed cotton yield with gradients of water deficits. Based on the intercept values and the degree of slope in comparison to mean and checks, the genotypes Laxmi, LRA-5166, Sharada, CPD-473, CPD-418, Anjali and HLS-321729 in G. hirsutum, DB-3-12, RAHS-14, H-6, R-51, H-135, H-124 and Jayadhar in G. herbaceum and A-82-1-1 and AK-235 in G. arboreum were found to be drought tolerant.
