Physical Properties of Potyvirus on Chilli (Capsicum annuum) of Doon Valley in Uttarakhand

Abstract

A virus is transmitted mechanically in the plant host. Potyviridae is a family of Potyvirus,consisting of a positive-sense RNA genome and filamentous particles. It has a single typeof protein coat. Mostly, this virus is identified in Leguminosae and Solanaceae family. Theplant virus is transmitted by mechanical inoculation and aphids. Chilli, cucurbits, potatoes,peas, tomatoes, and other plants were infected with the bean yellow mosaic virus, pea mosaicvirus, bean yellow mosaic virus, sugarcane mosaic virus, and peanut mosaic virus. Thermalinactivation point, dilution endpoint, longevity in vitro, and longevity in vivo were used toidentify the physical properties of a potyvirus. Several isolates mild and severe were collectedin the chilli plant. The infected plant developed necrotic leaf spots and chlorotic symptoms.
