Finding the Fighters:Maturity-adjusted resistance of potato cultivars to Verticillium wilt

摘要

Verticillium wilt of potato, also known as early dying disease, is caused by two soil-borne fungi of Verticillium: V. dahliae and V. albo-atrum. Of the two, V. dahliae is found in most of the U.S., whereas V. albo-atrum is found primarily in the northern U.S. and southern Canada. The fungus is capable of long-term survival in the soil and infects plants through the root system. From there it spreads to the vascular tissue, where it interferes with water and nutrient transport. Disease symptoms on potato leaves include wilting, chlorosis and eventually necrosis.
