ABSTRACT
Pakistan grows 200 thousand hectares of barani (rain-fed) and irrigated mungbean (Vigna radiata (L.) Wilczek). 80–85% of mungbean area is in Mianwali, Bhakkar, and Layyah of Punjab. Some viral diseases cause little economic damage, while some do. Thus, mungbean viral traits, differentiating features, and dispersion must be studied critically. Mungbean Yellow Mosaic Disease (MYMD) is a whitefly-transmitted viral disease. Infected plants have uneven yellow-green spots. Diseased plants develop late and produce few flowers and pods. MYMD causes 85% of economic losses. Begomovirus is a Begomovirus. DNA-A and DNA-B make up its single-stranded genome. The virus’s virulence and symptoms need both components. The sequencing of both components showed considerable variation between old-world and new-world viruses. Cultural practices, insecticides, and virus-resistant mungbean cultivars may help suppress the disease. MYMD-resistant NIAB mungbean lines include 1429, 3198, 3845, 3850, 3854, and 3881 (Schreinemachers et al., 2019). A recent study has revealed resistant varieties NM-5, NM-7, NM-68, NM-69, M 20-21, and M 22-24. This review guides research and MYMD-resistant cultivar development in the nation. Mungbean virus behavior, evolution, and dispersion must be studied to protect mungbean farming. This will help produce resistant cultivars and effective management measures. To combat MYMD and preserve mungbean production in Pakistan, research institutes, agricultural extension agencies, and farmers must work together.
