Abstract

The study was conducted to know the alternate hosts of Mungbean Yellow Mosaic Virus (MYMV) disease on greengram by cross inoculated with virus on several crops and weed hosts under laboratory through insect vector whitefly (Bemisia tabaci). The results revealed that the causal virus of the disease was successfully transmitted from greengram to greengram (Vigna radiata), Nicotiana benthamiana, Blackgram (V. mungo), Horsegram (Macrotyloma uniflorum), Pigeonpea (Cajanus cajana) Soybean (Glycine max), Cowpea (V. ungiculata) and weed hosts viz., Acalypha indica, Malvestrunm coromandelium, Croton bonplandianum, Euphorbia geniculata, Alternenthera sessile and Phyllanthus madraspatensis, while Parthenium hysterophorus did not show any symptoms. The study indicated that, these host plants served as potential alternate hosts and major source of virus inoculum for MYMV disease during the off season.
