Peanut mottle virus

Family   : Potyviridae
Genus    : Potyvirus
Acronym  : PeMoV

Introduction

Peanut mottle virus (PeMoV) is a plant pathogenic virus of the family Potyviridae. PeMoV seed-borne in groundnut, and probably occurs wherever groundnuts are grown. It induces greenish mottle symptoms in peanuts. It also infects soybean, pea, french bean and Cassia spp. It naturally spreads through infected seeds and aphids. Seed transmission can result in 25% yield reduction.

Major Diseases

Mottle disease

Geographical Distribution

Haryana, Karnataka, Punjab, Andhra Pradesh, Maharashtra and Gujarat.

Particle Morphology

Flexuous filamentous particles of about 740-750 nm long.

Transmission Method

Transmission by Myzus persicae (Sulz.) and Aphis craccivora in a non persistent manners. Virus transmitted by mechanical inoculation and by seed.

Detection

ELISA and RT-PCR
