Abstract: Major fruit crops were tested against twelve isolates of Colletotrichum gloeosporioides under controlled conditions. Inoculated fruits were assessed on the basis of virulence of the isolates and reaction of a particular variety was expressed in Virulence Index (VI). There was considerable variation in virulence and susceptibility within isolates and fruit crops. Isolates CgSD – 4, CgPD -1 and CgGJ 11 was found to be highly virulent (VI – 5.58, 5.03 and 4.46), CgBN – 9 as extremely less virulent (VI-1.96), and other isolates were highly virulent, moderately virulent, less virulent irrespective of fruit crops. Fruit crop guava were found to be extremely succeptible as displayed maximum mean of VI – 5.58, respectively irrespective of isolates. Resistant fruit crops pomegranate and banana showed uniform resistant reaction against twelve isolates of the pathogen. The interaction between isolates X fruit crops was also statistically significant. Highest VI (11.99) was recorded in the interaction between CgSD – 4 X sweet orange.
