Abstract
Mungbean (Vigna radiata L.) and urdbean (Vigna mungo L.) are major pulses crops predominantly cultivated during rainy season in northern and central India and during winter season in costal belt. In India, mungbean and urdbean productivity is constrained by a number of foliar and root diseases. Exploitation of host plant resistance for the development of high yielding varieties is the most economical and feasible component of integrated diseases management (IDM), hence remain a major objective of the crop improvement programmes around the world. The present investigation was undertaken to identify resistant donors against yellow mosaic disease (YMD) and therefore 200 germplasm accessions of mungbean and 100 of urdbean procured from ICAR-National Bureau of Plant Genetic Resources (ICAR-NBPGR), New Delhi and ICAR-Indian Institute of Pulses Research (ICAR-IIPR), Kanpur were phenotyped under natural field conditions, besides molecular characterization of viral pathogen and monitoring growth parameters.
