Field screening of 52 mungbean genotypes for resistance against whitefly, Mungbean Yellow Mosaic Virus (MYMV) and Cercospora leaf spot was carried out during Rabi and Kharif on 2015-2016. Population of whitefly ranged from 2.5 to 7.7 no./3 leaves while MYMV incidence ranged from 13.7 to 66.2 per cent. Two cultures viz., VBN 2 and CO 8 recorded low mean population of whitefly 2.5 and 2.7 no/3 leaves, respectively followed by VBN-3 (2.9 no. /3 leaves), PDM-54 (3.1 no. /3 leaves) and GM 4 (3.5 no. /3 leaves) whereas RM 612 recorded high mean population of whitefly (7.7 no. /3 leaves) followed by VGG-07-007 (7.1 no. /3 leaves) and VGG-007-002 (7.6 no. /3 leaves). MYMV incidence was low in VBN 2(13.7%) followed by Co 8 (20.0%) and VGG-10-002 (17.5%) while high in RM 612 (66.2%) followed by VGG-007-002 (60.0%) andVGG-07-007 (58.7%). Based on 0-5 scale, none of the entries were found to be highly resistant/ resistant to MYMV. However, nine genotypes were found to be moderately resistant. With regard to Cercospora leaf spot screening based on Rating Scale and Per cent Disease Intensity (PDI), minimum PDI was recorded in Co4 (6.6) followed by VGG-099-021 (9.4) and hence regarded as resistant while SLM-130(16.6) showed moderately resistant reaction followed by GM4 (18.6).
