STABILITY ANALYSIS IN SHORT DURATION CULTIVARS OF SWEET POTATO (IPOMOEA BATATAS L.)

Published on

Eleven short duration cultivars of sweet potato (Ipomoea batatas L.), Kalmegh, 80/168, S 30,
V 35, X24, X69, C 71, Cross 4, 76 OP/217, 76 OP/219 and H 268 were evaluated for marketable
tuber yield and yield contributing characters on lateritic soil with 6.4 pH. The varieties
exhibited significant differences in marketable tuber yield. Variety 76 OP/219 produced
maximum mean marketable tuber yield (17.2 tonnes/ha) because of highest number of
tubers/plant and minimum weevil infestation. The lowest marketable tuber yield was
recorded in H 268 (2.1 tonneslha) due to lowest number of tubers/plant and minimum
harvest index. Varietiell80/168, S 30, V 35, X 69 and Cross 4 gav!! comparable marketable
tuber yield with each other. However, the varieties X 69 (14.4 tonnes/ha), V 35 (14.4
tonnesiha) and Kalmegh (8.6 tonneslha) were stable for marketable tuber yield.
