Abstract
In 1998, Verticillium sp. (CE98Vt1 and CE98Vt2) were isolated from discolored vascular structures of potato tubers sold at a market in Chiba Prefecture. These isolates were identified as Verticillium tricorpus on the basis of cultural and morphological characteristics and PCR diagnosis. This observed vascular discoloration of the potato tuber was demonstrated in three cultivars (Touya, Toyoshiro, and Waseshiro) among eight cultivars by inoculation to seedlings. External and internal symptoms of these isolates were not distinct in potato plants. The virulence of these isolates to potato was very low as compared with Verticillium dahliae. These two isolates were not pathogenic to Chinese cabbage, eggplant, green pepper, larkspur, parsley, snapdragon, soybean, tobacco, and tomato. This is the first report of V. tricorpus from potato in Japan.
