A seed-borne, aphid-transmitted virus was found infecting mungbeans (Vigna
radiata) in various regions of Iran. The virus produced deformation, puckering,
rolling, blistering, and mosaic symptoms on the foliage of virus-infected
mungbeans. The pathogen was seed-borne in mungbean (8 to 32%) and comon bean
(Phaseolus vulgaris) (approx. 7%). The mungbean virus adversely affected growth
and yields of mungbean, especially when infection occurred before pod set.
Yields from 11 mungbean lines infected from seed were reduced by 31 to 75%. Two
mungbean lines were highly resistant to the virus in field trials at Karaj,
Iran. The virus was transmitted in a stylet-borne manner by several aphid
species, including Aphis craccivora, Acyrthosiphon pisum, and Acyrthosiphon
sesbaniae. Electron micrographs of negatively stained leaf-dip preparations
showed that infection was associated with flexuous particles approx. 750 nm in
length. From host range studies, symptoms, seed and vector transmission,
serology, and particle morphology, the mungbean virus was identified as a
strain of bean common mosaic virus. [AS]

Bean common mosaic virus was seed-borne in all of the 17 mungbean germplasm
entries tested. The rate of seed-transmission varied from 2 to 14%. [THH]

Blackgram plants systemically infected with bean common mosaic virus (BCMV)
either had their entire inflorescences transformed into leaf-like structures or
had greatly reduced numbers of flowers. BCMV infection did not affect pollen
viability, seed color, and seed viability. It did, however, greatly reduce the
number of pods per plant and grain yield. [EMS]

Bean common mosaic virus was successfully detected in blackgram seeds by
indicator-inoculation, growing-on and microprecipitin tests. Any one of these
tests, depending upon facilities available, can be used to detect the virus in
blackgram seeds. [AS]
