Abstract
This research was conducted to investigate the incidence of viral infection in Samcheok-shi and Jeongseongun, main garlic growing areas of Gangwon province in Korea. Four primers sets (GLV, LYSV, GCLV, OYDV) were used for RT-PCR to test of 100 samples collected from each location. Infection rates of GLV, LYSV, GCLV and OYDV of garlic samples from Samcheok-shi and Jeongseon-gun were 95, 95, 92 and 33%, respectively. All garlic samples tested in this research were infected at least one virus. Coinfection of 3 kinds of virus (GLV, LYSV and GCLV) and 4 kinds of virus (GLV, LYSV, GCLV and OYDV) were 60 and 25%, respectively. While infections of GLV, LYSV and GCLV were evenly found in both two regions, OYDV infection of garlic samples collected from Jeongseon-gun was higher than Samcheok-shi. Viral infections at garlic fields of whole country and Gangwon province are very serious now. Therefore, it is very necessary to develop technic for virus-free bulb and renew seed bulb of garlic.
Key Words: Garlic, RT-PCR, Virus-free bulb
