Introduction

Grapevine leafroll-associated virus 1 (GLRaV-1) cause reddening of interveinal areas and downward rolling of leaves of infected plants. The disease first observed in 2010. GLRaV-1 was detected in two cultivars, Shiraj (Nashik region) and Pinot Noir (Pune region), using DAS-ELISA. GLRaV-1 was detected either alone in Pinot Noir or as mixed infection with GLRaV-3 in Shiraj. The presence of the virus in the two cultivars was confirmed by reverse transcription-PCR assay
