Genetic resistance in mungbean and mashbean germplasm against mungbean yellow mosiac begomovirus

In order to identify sources of resistance against mungbean yellow mosaic (begomo) virus (MYMV), 110 lines of mungbean and 134 of mashbean were evaluated under field conditions. Out of 110 mungbean lines, 85 were found as highly resistant (HR), 14 resistant (R) and 5 moderately resistant (MR). Only six accessions were graded as susceptible (S) to highly susceptible (HS). In case of mashbean, 43 accessions were found as highly resistant (HR), 28 resistant (R) and 18 moderately resistant (MR), whereas, the others 45 were susceptible to highly susceptible. Although resistance against MYMV in mungbean and mashbean has been previously reported, but this study reports some additional new sources of resistance to be included in breeding programme to develop MYMV-resistant varieties in the country.
