Absence of resistant/tolerant genotypes against diseases and insect pests in urdbean (Vigna mungo (L.) Hepper) are one of the main reasons for their low yield in India. During the summer and Kharif season, yellow mosaic disease epidemically damages the crop in most of the urdbean growing areas of India. Identification of resistant genotypes is one of the most important aspects in the management of viral diseases, which might be the best possible solution to the viral disease problems. For the purpose of identifying resistance/tolerance in urdbean germplasm, field screenings were conducted for four consecutive seasons during summer and Kharif, 2013 & 2014, comprising of 100 test entries. Screening was done under natural environmental field conditions against yellow mosaic disease (YMD). Out of 100 entries tested, only one entry, NDU 12-1 was found to be disease free, nine genotypes (IPU 10-23, KUG 586, Mash-338, NDU 12-300, PU 09-35, UH 07-06, Uttara, VBG 10-008, and VBN 6) found to be highly resistance and four genotypes (Kopergaon, RUG-44, VBG 09-005, and NDU 11-201) showed resistance consistently in both the seasons over two year. However, out of 100 genotypes, only four genotypes i.e. VBN (BG) 7, IPU 2-43, KUG 586 and KUG 503 were found to be superior for seed yield as well as resistant to MYMV.
