Screening of Mung Bean Genotypes against Yellow Mosaic Virus (YMV) Resistance

Abstract

Experiment was conducted to identify the resistant Mung bean varieties against MYMV in Kharif during 2017. Ten Indian mung bean genotypes obtained from AICRP on Arid legumes, RARI, Durgapura, Jaipur, were used in the screening experiment and the obtained results revealed that there was significant variation among the genotypes for resistance against MYMV. Based on the average MYMV score, only two genotypes (IPM 02-3 and IPM 0205-7) were found completely free from the disease and the plants had maximum chlorophyll content whereas IPM-409-4 and RMG 991 were found resistant and chlorophyll content was low as compared to the highly resistant genotypes. The rest of six genotypes observed moderately resistant, moderately susceptible, susceptible and highly susceptible to the disease.
