Root rot/Charcoal rot, Alternaia leaf spot, Bacterial pustule and Yellow Mosaic Virus are important one disease in Vidarbha region of Maharashtra. Thirty advance lines of soybean were screened for these diseases in protected and un-protected condition under natural field conditions and results revealed that four entries viz.NRC-94, JS-20-69, JS 20-71 and KDS-699 were shown Resistant High Yield (R-HY) reaction to disease complex while NRC-92, KDS 705, KDS-378 and JS 20-41 exhibit Susceptible High Yield Tolerance (S-HY (T)) reaction to disease complex. Only one entry (SL-958) initiates Resistant Low Yield (R-LY) reaction. Rest of the tested advance lines showed Susceptible Low Yield (S-LY) reaction.
