infected plants were not altered significantly. The number and weight of
nodules were considerably reduced due to virus infection. A remarkable
reduction in number of pods and weight of grains caused by virus infection was
observed. A regression equation to predict the loss in yield based on growth
retardation has been formulated. [AS]

Two viruses from mungbean isolated from Iranian samples were examined. One
with filamentous, flexuous particles, transmissible by aphids, and
serologically related with bean yellow mosaic virus, has been identified as
mungbean mosaic virus (MMV). It compares closely with the strain of bean common
mosaic virus (BCMV) seed-borne in mungbeans in Iran. Reasons for considering
MMV as distinct, and not a strain of BCMV, are elaborated. Another seed-borne
virus in mungbean with isometric particles was identified as a strain of
cucumber mosaic virus (CMV). The virus isolated from an Indian blackgram sample
constitutes new records of a natural host other than broadbean and of seed
transmission as such. [AS/THH]

The study indicates that the virus causing mosaic and ringspot symptoms in
mungbean has a wide distribution in Sri Lanka and its host range includes the
common weed species and many crops. The biological properties of this virus
closely resemble those reported strains of tobacco ringspot virus. [THH]

This report characterizes the viruses causing mosaic mottling and leaf
crinkle in mungbean and urd bean which occur in India. Several varieties were
also evaluated for their susceptibility/resistance, changes occurring in
chlorophyl, protein and nucleic acid contents in diseased plants; inhibition of
viruses by antiviral chemicals; and effect of insecticides and oils to check
field spread of yellow mosaic virus were also studied. [GFI
