Abstract : Mango germplasm comprising 43 cultivars was evaluated in Pakistan for the level of the panicle malformation disease (Fusarium mangiferae) intensity. The intensity varied significantly among the genotypes. Out of the tested cultivars, 4 were tolerant, 27 were moderately tolerant, 5 were moderately susceptible and 7 were highly susceptible to malformation. Disease incidence frequency was highest in Lab-e-Mashooq (68.70%), followed by G.M. Wala (64.28%) and lowest in Sensation (7.20%) and Gulab Khas (7.8%). The lowest affected cultivars may be used for incorporating their tolerance in other commercial cultivars through breeding programmes. The incidence rate was higher (38.69%) in 6 commercial cultivars under central Punjab ecological conditions than that (26.70%) in the Southern (Multan) region. However, the tolerance in genotypes seems specific to ecological regions and the growers of the highly susceptible cultivars should be very careful and regular in carrying out control measures.
