Abstract : Cultivar Kesar recorded maximum number of panicles cubic-1 meter (12.94) which was significantly superior over others. Panicles shoot-1 were maximum in Fernandia (30.33) followed by Doodhpedha (25) and Vanraj (23.60). The Neelam recorded maximum number (63.67) panicle-1 and percentage of perfect flowers (33.61%). Maximum number of hermaphrodite flowers were noted in Vanraj (396.73), which was significantly greater than Fernandia (278.75), Kesar (266.06) and Balanpur Baneshan (261.00). The varieties Doodhpedha (27.43%), Pulivora (27.03%) and Sindhu (26.17%) recorded significantly less percentage of perfect flowers. Significantly higher percentage of male flowers (90.86%) were observed in cv. Alphonso followed by Balanpur Baneshan (89.27%). The cultivars like Neelam (1.99:1), Doodhpedha (02.97:1), Pairi (3.05:1) and Sindhu (3.27:1) exhibited comparatively narrow sex ratio resulting into satisfactory initial fruit-set. Whereas, varieties like Kesar (12.80:1), Balanpur Baneshan (12.43:1), Totapuri red small (12.04:1) showed very wide sex ratio resulting in higher fruit set. The regular bearing varieties like Totapuri (3.22), Neelam (2.56) expressed higher fruit set followed by Vanraj (1.87) as compared to other. Proportion of hermaphrodite flowers in all the fifteen cultivars was quite variable in respect to direction of plant.
