Four isolates causing mosaic mottling in mungbean are described. They were
transmissible by sap and also by the aphid vectors Aphis gossypii, A.
craccivora and Myzus persicae. Of the foi'r isolates studied, GGM 2 and GGM 3
had similar host ranges and physical properties and infected Vigna radiata and
V. mungo systemically while th.ey produced necrotic lesions on Phaseolus
vulgaris and Cyamopsis tetragonaloba. The GGM I isolate caused systemic
infection on Pisum sativum, Medicago sativa and Physalis floridana while GGM 4
infected V. mungo and Solanum nigrum. The isolates were not serologically
related to tobacco mosaic virus, cowpea mosaic virus, soybean mosaic virus or
potato virus, but all were serologically related. Hence, the virus reported
here is tentatively considered as new and is designated as mungbean mosaic
virus. [ASJ

In leaves of ten cultivars of blackgraw (Vigna mungo) viz. T-9, T-27, T-65,
T-77, Mash 1-1, Mash-48, L 41-43, Co.1, No.55 and Khargoan, the blackgram
mosaic virus caused a decrease in chlorophyll content, catalase activity and
increase in peroxidase activity in comparison with their healthy counterparts.
Chlorophyll contenL and peroxidase activity increased with the age of the plant
but catalase decreased. Different cultivars varied in their response to
infection. [AS]

Various types of mosaic symptoms on mungbean (Vigna radiata) and blackgram
(V. mungu) were caused by two different viruses tentatively designated as
mung/urd mosaic virus I (MUMV 1) and mung/urd mosaic virus 2 (MUMV 2) in
Haryana. Symptoms produced by these two viruses on several other leguminous
plants were different. Vigna catjang and Dolicos lablab were the distinct local
lesion hosts of MUMV 1 and MUMV 2, respectively. The maximum number of local
lesions were produced by MUMV I on primary leaves of V. catjang at the time of
initiation of first trifoliate leaf and not later. Both viruses wfpre easily sap
and seed transmitted but differed in host range, host reactions, physical
properties and were serologically unrelated. MUMV I was found more related to
bean common mosaic virus and MUMV 2 to cowpea mosaic virus than other
leguminous viruses infecting mungbean and blackgram. [AS/THHJ
