Abstract
Soybean (Glycine max L.) is a highly valued crop due to its
remarkable protein content of 40 per cent and high-quality oil content of 20
per cent. However, its production potential is consistently hindered by various
pests and diseases. Of particular concern is the yellow mosaic disease, caused
by the mungbean yellow mosaic virus (MYMV) and mungbean yellow mosaic India
virus (MYMIV) transmitted by the whitefly (Bemisia tabaci), creating a
significant threat to soybean cultivation worldwide. A study was conducted at
the Agricultural Research Station (ARS) in Bidar, India during 2023-24 aimed at
the identification of resistant genotypes against yellow mosaic disease in
soybean. A total of 67 genotypes including the susceptible check variety
JS-335, were screened under natural epiphytotic conditions. The experiment was
carried out in a paired row system in a randomized block design with two
replications. Among them, five genotypes-ARS-5, NRC-270, DS-1547, DLSb-6 and
NRCSL-8 exhibited resistance to yellow mosaic disease. Furthermore, DS 1589 and
DLSb 5 displayed moderate resistance, while 6 genotypes showed moderately
susceptible reactions. Additionally, 9 genotypes were found to be susceptible
and the remaining 38 genotypes displayed highly susceptible reactions to the
disease. The genotypes with YMV resistance would stand as a barrier against the
spread of the disease to newer areas and thus can boost the production and
productivity of soybean in the country.
