Charcoal rot and Aerial alight caused by Macrophomina phaseolina (Tassi) Goid and Rhizoctonia solani Kuhn, respectively are major biotic challenges across the country in soybean cultivation. The problem of disease can be overcome nicely by growing resistant variety and using integrated disease management practices. In this concern, for the identification of resistant source, total sixty genotypes including five check varieties namely Shivalik, JS 335, JS 95-60, JS 93-05 and NRC 7 were evaluated under high disease pressure during kharif 2019. The disease index of Rhizoctonia Aerial Blight (RAB) was varied from 0.75 to 37.50 per cent. Out of sixty, five and sixteen genotypes were exhibited highly and moderately resistant reaction against RAB, respectively. In case of Charcoal rot (CR), severity in nine genotypes were reported more than 50 per cent and sixteen genotypes shown absolute resistance. For both diseases, five namely JS 21-71, JS 20-31, TG x – 849 D-13-4, JS 20-42 and JS 20-75 shown absolute resistance to CR plus highly resistance to RAB. Whereas nine i.e. DS 3109, EC 251358, JS 20-79, JS 21-17, VP 1164, JS 20-69, JS 20-34, JS 20-53, MACS 1620 found to be absolute resistant (CR) plus moderately resistant (RAB).
