Abstract

Mungbean is an important legume crop due to its short behavior, nutritious and green mannuring nature. But it is highly affected by several diseases and other factors, which reduces the yield and seed quality. Mungbean yellow mosaic virus (MYMV) and Cercospora leaf spot (CLS) are the major disease of mungbean. Therefore, the present study was conducted to characterize the 34 genotypes of mungbean against MYMV and CLS disease during Kharif 2012 under two different date of sowing. The present study indicated that the none of the genotype was found immune, resistant to MYMV and CLS, whereas five genotypes namely DMS 03-17-2, IPM 2K-14-9, P 1131, DMS 02-11-4 and IPM 99-1-6 were found with moderately resistant reaction. These genotypes may be added in breeding program for improvement of mungbean.
