Abstract: Soybean (Glycine max (L.) Merill) is one of the most important oilseed - cum leguminous crop gaining importance during recent years due to its short duration, drought resistance, high yielding ability and nutritive value. It is the world’s foremost provider of protein and oil. In Karnataka, the area production and productivity of soybean were 0.27 m ha, 0.17 mt and 639 kg/ha, respectively (Anonymous, 2018). Soybean growing major states in the country are Madhya Pradesh, Maharashtra, Karnataka, Andhra Pradesh, etc. Among the fungal diseases infecting soybean crop, pod blight caused by Colletotrichum truncatum (Schew.) Andus and Moore, Colletotrichum gloeosporoides (Penz.) Penz. and Sac. and Rhizoctonia bataticola (Taub.) Butler is one of the most important and destructive disease. The experiment on screening of available genotypes has taken under natural epiphytotic condition at Ugarkhurdh, Belagavi during kharif of 2016 and 2017. Out of 235 entries None of them were immune or absolutely resistant, 6 genotypes viz., JS 97-52, AMS MBS-18, NRC 127, SL 1104, DSb 28-3 and DSb 30-2 showed resistant reaction to pod blight, most of the entries like PS 1347, RSC 10-46, SL 1074, DSb 32 and NRC 86 were moderately resistant and MACS 1520, PS 1569, RUS 2002-4 and RUS 2008-24 are moderately susceptible in reaction. Genotypes like Pusa 97-12, Shivalik, JS 335 and KDS 1045 were showed susceptible reaction and genotypes like KDS 869, KDS 921, KDS 980 and JS 93-05 are highly susceptible to disease.
