Mungbean [Vigna radiata (L.) Wilczek] is an important legume which can be grown in all three crop seasons viz., kharif, rabi and spring/summer in India, as sole or inter crop for grain and green manure. The production of mungbean is severely affected by mungbean yellow mosaic virus (MYMV) caused by begmoviruses transmitted by white fly, Bemesia tabaci. The absence of resistant/tolerant sources against MYMV disease leads to tremendous crop yield losses, with the aim of identifying the resistant source we carried out an experiment at UAS Dharwad, screened one hundred seven genotypes of mungbean germplasm lines against MYMV during summer season under field conditions. The germplasm was categorized in to resistant and susceptible depending upon severity of disease. The differential response of mungbean accessions to MYMV was determined and most of the genotypes studied were categorized as susceptible to moderately susceptible. In spite of the variable response to MYMV, the genotypes HUM 1, KM 15, KM 16, KM 24, KM 28, KM30, KM 36, KM 39, KM45, KM 47, KM 49, KM 51, KM 60, KM70, KM78 and KM 79 exhibited resistant reaction against the MYMV disease fourteen were moderately resistant and 30 were moderately susceptible. Remaining 30 accessions were classified as susceptible and 43 as highly susceptible accessions.
