The result of investigation on cowpea aphid-borne mosaic virus, an
important virus of cowpea in Iran, is reported. The virus has a wide host range
including mungbean cultivar Oklahoma 12. [THHJ

infective in the leaves of blackgram cv. T-9 desiccated over calcium chloride
for a period of 426-634 days at room temperature (12 to 40 C). These isolates
were
readily transmitted by sap but not by seed and aphids. The virus was
recovered from various parts (leaf, petiole, stem, sepal, petal, pollen,
carpel, root and root-nodules) of infected blackgram cv. T-9. Various cultivars
of Cajanus cajan (L.) Millsp (7); Vigna radiata Wilczek (7), V. mungo (11) and
V. sinensis (Torner) Savi. (8) were tested for susceptibility and reaction to
virus isolates. [AS/THH]

A mosaic disease of blackgram is described. The virus resembles cowpea
mosaic in host range, physical properties and insect transmission. This is the
first report of natural occurrence of an aphid-transmitted virus of the cowpea
mosaic group on blackgram from India. [THH]

Blackgram plants infected with bean yellow mosaic virus had an increased
respiration rate over healthy plants and higher polyphenol oxidase and ascorbic
acid oxidase activities, but a lower rate of net photosynthesis and reduced
chlorophyll and starch contents. Sugar content was higher at the time of
symptom appearance, but decreased afterward. [EMSJ
