Journal of Pharmacognosy and Phytochemistry 2020; 9(1): 355-360 E-ISSN: 2278-4136 P-ISSN: 2349-8234 JPP 2020; 9(1): 355-360 Interaction of putative virulent isolates among Received: 16-11-2019 Accepted: 18-12-2019 commercial varieties of mango under protected condition Devappa V Department of Plant Pathology, College of Horticulture, UHS Devappa V, Sangeetha CG and Ranjitha N Campus, GKVK Post, Bengaluru, Karnataka, India Abstract Sangeetha CG The present study was undertaken to know the interaction of the putative Colletotrichum gloeosporioides Department of Plant Pathology, isolates from different regions of Karnataka. The cultural characteristics among the 10 isolates studied, College of Horticulture, UHS showed that isolates Cg-1, Cg-2, Cg-4, Cg-5, Cg-6, Cg-7, Cg-8, Cg-10 were circular with smooth margin Campus, GKVK Post, both on 7th and 12th day of inoculation. Excellent sporulation was observed in Cg-8 and Cg-4 isolate, Bengaluru, Karnataka, India good sporulation was observed in Cg-3 and Cg-9 isolates whereas, medium sporulation in Cg-1, Cg-2, Cg-5, Cg-6 and Cg-7 isolates and poor sporulation was observed in Cg-10 isolate. Among the varieties Ranjitha N tested, none of them showed immune and resistant reaction to the disease under shade house condition. Department of Plant Pathology, Dasheri (20%) exhibited moderately resistant reaction, Totapuri (28%) and Himayudhin (29.70%) College of Horticulture, UHS Campus, GKVK Post, exhibited moderately susceptible reaction whereas, Mallika (35%) and Kesar (47.30%) exhibited Bengaluru, Karnataka, India susceptible reaction. Alphanso (62.50%), Neelam (56.20%) and Raspuri (75%) exhibited highly susceptible reaction.
