Fifty sweet potato clones were field screened for drought resistance from February, 1990 to May, 1991. The study aimed to identify the morphological and yield characters associated with drought resistance in sweet potato and to select parents for evaluation. Results indicated that number of leaves (40 DAP), vine number (55 DAP), storage root yields (40, 55 and 70 DAP), harvest index and canopy cover (40 DAP) were significantly associated with storage root yield at 90 DAP. Among the clones evaluated, V242 was the highest yielder followed by L063, N001, Kalibre, M1 and Miracle.
