Abstract
Tospoviruses of the family Bunyaviridae are very significant viral pathogens in several crops in India. A total of 11 tospovirus species has been recognised worldwide, of which five tospovirus species, Groundnut bud necrosis virus (GBNV), Groundnut yellow spot virus (GYSV), Iris yellow spot virus(IYSV), Watermelon bud necrosis virus (WBNV) and Tomato spotted wilt virus (TSWV) are known to occur in India. In addition to these tospoviruses, a tentative member, Capsicum chlorosis virus (CaCV) has also been documented in India. Tospoviruses are major constraints in vegetable and pulse crops in India. GBNV is the most prevalent and destructive tospovirus in India, which has been detected in 30 different crops and weed species belonging to eight families and other tospoviruses are restricted in nature with reference to host and geographical region. The present chapter summarises the research work on tospoviruses carried out in India during the past more than half a century.
