Abstract

The study was carried out on forty four mango cultivars to group them based on degree of resistance to malformation. Intensity of malformation varied significantly among the mango cultivars. Mango cultivars Bhadauran and Elaichi were found to be completely free from the disease, while minimum disease intensity was recorded in mango cultivars Rosary (3%), Rataul (4%), Alphan (8%), and Ramkela (9.5%), which were categorized as tolerant. Fifteen mango cultivars were moderately susceptible (10.1–20%), while another fifteen cultivars were susceptible (20.1–50%). The highest rate of mango panicle malformation intensity was recorded in eight cultivars including; Zill, Ratna, Amrapali, Tommy Atkins, Eldon, Neelum, Extrema and Iturba which were categorized as highly susceptible cultivars (>50% malformation).
