Abstract : The incidence of panicle malformation in 10- and 20-year-old trees of 10 mango cultivars was studied during 1987-88 and 1988-89. All cultivars except Bhadauran were susceptible. The highest incidence occurred in Khasulkhas (34.51% of panicles malformed), followed by Gulabkhas (29.58%), Dashehari (20.50%) and Chausa (16.39%). Percentage malformation was significantly lower in Safeda Malihabad, Rataul, Bombay Green and Langra, averaging 8.19-11.65%. Average percentage malformation was higher in the older trees than in the younger ones (13.92 vs. 11.81%), but the older trees produced more normal panicles than the younger trees (839.20 vs. 752.50/tree) as well as more malformed ones (133.85 vs. 98.24/tree). Among the cultivars, Safeda Malihabad produced the most panicles (on average 1198.83/tree, 1101.00 of which were normal), while Bhadauran had the most normal panicles (1127.00/tree).
