SCREENING OF MUNGBEAN GERMPLASM AGAINST MUNGBEAN YELLOW MOSAIC VIRUS AND URDBEAN LEAF CRINKLE VIRUS Department of Plant Pathology, College of Agriculture, University of Sargodha, Sargodha, Pakistan

Abstract

Mungbean [Vigna radiata (L) Wilczek] is considered as a pulse crop having high nutritional value containing large amount of protein contents. Destructive diseases of mungbean causing poor seed quality as well as reduce the yield are Mungbean Yellow Mosaic Virus (MYMV) and Urdbean Leaf Crinkle Virus (ULCV). The experiment was conducted in field conditions at research area of Department of Plant Pathology, University of Agriculture, Faisalabad. Screening of twenty mungbean varieties/lines was performed against both viruses. A check was sown after every four cultivars named as Kabuli mung. Not a single cultivar exhibited highly resistant and resistant reaction against MYMV along with ULCV. In case of MYMV moderately resistant response showed by three varieties (Azari-06, NM-2011, NM-2006), moderately susceptible response by one variety (NM-121-125), susceptible response by four cultivars (NM-92, NM-54, 11002, NM-28) and highly susceptible response includes twelve cultivars (NM-51, NM-98, NM-20-21, NM-19-19, 7006, 11009, 11010, 11003, 11011, 11007, 110047008). Whereas, response of mungbean cultivars against ULCV showed that three varieties were found moderately resistant (Azri-06, NM-2011, NM-2006), four cultivars were found moderately susceptible (NM-54, NM-28, 11002, NM-92), four cultivars were found susceptible (NM-51, 11003, 11011, 11004,) and nine cultivars were found highly susceptible (NM-98, NM-20-21, NM-19-19, NM-121-125, 7006, 11009, 7008, 11010, 11007).
