Abstract  The effect of garlic yellow streak virus (GYSV) on red garlic (Y strain), traditionally grown in the Pukekohe region of New Zealand, was found to be minimal; emergence from infected cloves was 92% and infected plants generally produced bulbs of good size and quality. In contrast, the effect on the popular Japanese cultivar--`Fukuchikei White'--was severe; only 56% of infected cloves emerged and only 42% of the emerged plants subsequently produced bulbs. Natural GYSV infection of virus-free garlic, cultivar `Printanor', was delayed by a 2 km separation from the nearest infected garlic crop, but the final disease incidence was not affected.
