Mungbean yellow mosaic virus (MYMV) is an important production constraint in mungbean cultivation in Pakistan. The yield further decreases if susceptible varieties are cultivated. By using cultivars resistant to MYMV, the losses can be reduced. As the host status of mungbean genotypes grown in Pakistan is not known, therefore, in the present study 23 varieties/lines of mungbean collected from various sources were tested for their relative resistance or susceptibility to MYMV under field conditions. The results revealed that none of the entries was found highly resistant. Six entries viz. BRM-325, BRM-345, BRM-363, BRM-364, BRM-366 and NM-2011 were found to be resistant and ten genotypes/lines namely BRM-311, BRM-312, BRM-321, BRM-331, BRM-335, BRM-365, BRM-378, BRM-382, BRM-343 and BRM-353 appeared as moderately resistant. On the contrary, five genotypes Chakwal-06, BRM-334, BRM-348, BRM-354 and BRM-356 were rated as moderately susceptible to the disease. Likewise, two entries each (BRM-349 and BRM-350) and (Mash bean and Pigeon pea) showed susceptible and highly susceptible responses to the virus respectively.
