Abstract

Yellow Mosaic Virus, Alternaia leaf spot, Bacterial pustule and Charcoal rot are major diseases of soybean in Vidarbha region of Maharashtra. Thirty two advance lines of soybean with ten checks were screened for these diseases in protected and un-protected condition under natural field conditions and results revealed that four entries viz. SL 955, KDS 705 and JS 20-71 were shown Resistant High Yield (R-HY) reaction to disease complex while JS 20-53, SL 982, and DS 2705 exhibit Susceptible Resistant Low Yield (R-LY) reaction to disease complex. Among tested entries like PS 1543, KDS 726 KDS 743, JS 20-79 JS 20-89, RVS 202-4, MACS 1407, NRC 93, NRC 94, RKS 113, JS 20-69 initiates Susceptible High Yield Tolerance (S-HY (T) reaction. Rest of the tested advance lines showed Susceptible Low Yield (S-LY) reaction.
