yellow mosaic virus. INDIAN PHYTOPATHOLOGY, v.27(3):429. [EnJ (REP.MB-0545)
Inoculations using viruliferous whiteflies established that Cosmos
bipinnatus and Phaseolus vulgaris cv Manitou were hosts of mungbean yellow
mosaic virus. It seems that the host range of MYMV is restricted to
Leguminosae, Compositae and Graminae. [EMS]

between mung bean yellow mosaic virus and its vector Bemisia tabaci. INDIAN
PHYTOPATHOLOGY, v.27(4):459-462. [En] (REP.MB-0474)
Mungbean yellow mosaic virus (MYMV) persisted in female and male adults of
Bemisia tabaci for a maximum of 10 and 3 days before, respectively, but not
throughout the life span of the vector. Female adults remained alive and
infective for a longer time as compared to males. The results of the experiment
on transovarial transmission were negative. The nymphal stage of B. tabaci can
acquire the virus. Adults were able to acquire MYMV from inoculated
Mahaillupalam-1 blackgram plants I to 3 days before these plants actually
showed initial symptoms. MYMV appears to be a circulative type. [AS]

Pradesh. CURRENT SCIENCE, v.43(21):689-b90. [En] (REP.MB-2594)
Soybean was infected with yellow mosaic in all soybean-growing areas
surveyed in Uttar Pradesh in 1971 and 1972. Virus-infected plants were slightly
stunted and produced only a few branches. Leaflets were smaller and narrower
and showed bright yellowish patches scattered over the lamina. Pods were fewer,
smaller, and contained fewer seeds. The virus could be transmitted only by the
whitefly, Bemisia tabaci but not through sap, aphids, or seed. It infects
plants of the family Leguminosae only, viz., Glycine max, Vigna mungo, V.
radiata, V. sinensis and Phaseolus vulgaris. The virus resembles mungbean
yellow mosaic virus in symptomatology, host range and transmissibility.

Vigna radiata W. (Baisaki mung) infected by yellow mosaic virus produced
mainly small white nodules. Several isolates of nodule bacteria were obtained
from infected and healthy plants. Of these, six strains of Rhizobium, two from
nodules of healthy plants and four from nodules of infected plants were studied
for some cultural biochemical and antigenic properties. The results did not
show any critical difference between Rhizobium strains in relation to virus
infection of the host. [ASJ
