Abstract

Two hundred germplasm lines along with six commercial varieties of mungbean were evaluated for resistance to yellow mosaic virus, cercospora leaf spot and powdery mildew at four sowing dates spread over two seasons under field conditions. Genotypic differences were observed for resistance to these three diseases. One hundred and sixty nine genotypes were identified as resistant to yellow mosaic virus. Out of these, 18 genotypes had less than 1% leaf area affected. Thirty five genotypes were found to be resistant to cercospora leaf spot. One hundred and seventy four genotypes were identified as resistant to powdery mildew. Twenty one genotypes were found to be resistant to all the three diseases.
