Abstract:
Greater amount of variation was found by screening 110 mungbean accessions against MYMV during Kharif season under field conditions at FoA, Wadura Sopore, Jammu and Kashmir. Depending upon the severity of disease, the germplasm was categorized into resistant and susceptible genotypes. Disease severity significantly increased due to prolonged inhabitation of whitefly and remained with it till maturity of crop. Development of insecticide resistance in whitefly increased the frequency of whitefly outbreaks which eventually increased disease incidence. On differential response of germplasm to MYMV, eight (8) genotypes were found highly resistant (HR), thirty four (34) resistant (R), five (5) moderately resistant (MR) to disease. Fourteen (14) were found moderately susceptible (MS), forty seven (47) susceptible (S) and eight (8) highly susceptible (S).
