Abstract: Determination of fungi associated with malformed tissues of mango was done on different local and exotic cultivars during the year 2000-2001. Five mango growing districts of the Punjab were selected for the study with three locations in each district. A total of 75 malformed samples and 750 tissues (10 tissues / sample) of 5 standard local cultivars and 1500 tissues of exotic cultivars were assayed. Fusarium mangiferae proved to be the dominant fungus with 100% sample's infection in all the five districts. Maximum within tissue infection of 98% was observed in Okara and Sahiwal districts. Local variety Anwar rataul and exotic Tomy atkin appeared to be the most infected varieties giving 92.0 and 96.0% tissue infection, respectively.
