Mungbean (Vigna radiate L.) is a fast-growing warm seasonal pulse crop that has high nutritional and economical importance. It is grown for its seeds that have high protein content. It belongs to the family Fabaceae, widely distributed throughout the world mainly in Asian countries. In Pakistan, about 88% of mungbean production has occurred in the Punjab province. Various biotic and abiotic factors are responsible for a significant yield and productivity reduction in mungbean crop. While the major loss of mungbean production is mainly due to mungbean yellow mosaic virus (MYMV) which may lead to 5-100% yield loss. This disease is caused by geminiviruses, belong to begomovirus genus. To overcome this loss due to MYMV, host resistance is preferred over cultural and chemical control methods. This review summarizes the importance of begomoviruses to cause the disease, the role of vector whiteflies, implementation of various management strategies including host resistance and marker-assisted breeding. Molecular marker-assisted breeding for resistance or tolerance in mungbean against MYMV is an effective approach to combat this disease. Different molecular markers have been used to identify and characterize the mungbean resistance genotypes against MYMV. Several molecular markers have been identified through Bulked Segregant Analysis (BSA) which are linked to this disease.
