Mungbean [Vigna radiata (L.) Wilczek] is one of the most important grain legumes grown particularly in Asia. The production of mungbean is severely hampered by mungbean yellow mosaic virus (MYMV) caused by begomoviruses transmitted by whitefly, Bemesia tabaci. The absence of resistant/tolerant sources against MYMV disease leads to tremendous crop yield losses. To identify the sources of resistance in mungbean against MYMV, 35 genotypes were screened under natural conditions and categorized into different reaction groups using rating scale. In the present study, the screened genotypes were re-evaluated under screen-house conditions in order to confirm the sources of resistance against MYMV disease incidence. Out of them, 2 were categorized as resistant (R), 6 moderately resistant (MR), 12 moderately susceptible, 14 susceptible (S) and 1 as highly susceptible (HS). The resistant and highly susceptible genotypes could be used as parents for the development of mapping population in order to validate the molecular markers to facilitate marker-assisted selection for the development of MYMV resistant breeding lines.
