Screening of mungbean genotypes against mungbean yellow mosaic virus disease under natural condition and its management

Abstract

To identify resistance sources against Mungbean Yellow Mosaic Virus (MYMV) screening was done under natural condition at Pulses Research Unit, Dr. PDKV Akola, during summer 2017. Among seventy four genotypes tested, all genotypes were procured from Pulses Research Unit, Dr. PDKV Akola, The data on incidence of yellow mosaic virus was recorded at different interval. The average incidence of YMD was recorded from 0 to 68.42 per cent in various genotypes. Further, tested genotypes were grouped into different categories based on 0-9 disease scale. Among the 74 genotypes of mungbean eight were found resistant, nineteen genotypes were moderately resistant, thirty seven were susceptible, five genotypes were moderately susceptible and five were highly susceptible to yellow mosaic virus of mungbean. The spraying of Dimethoate 30% EC @ 2 ml/lit was found best over treatments for managing the YMD whereas least population of vector was observed in sprays with Allium sativum (10%) @ 10 ml/lit.
