Horsegram yellow mosaic virus
Family : Geminiviridae
Genus : Begomovirus
Acronym : HgYMV
Introduction
Horsegram yellow mosaic virus (HYMV) is a plant pathogenic virus that cause yellow mosaic disease in different leguminous species. It is a whitefly transmitted virus, the severity of the disease increases during summer months.
Major Diseases
Yellow Mosaic Disease

Andhra Pradesh, Karnataka.
Particle Morphology
Geminate virus particles 15-18 x 30 nm.
Transmission Method
Transmitted by a vector Bemisia tabaci (Aleyrodidae) in a persistent manner; Virus not transmitted by mechanical inoculation; not transmitted by seed.
Detection
ELISA, ISEM and PCR
