Abstract
Taiwanese isolates of Phytophthora infestans were examined for mating types and pathogenicity to tomato and potato. A total of 70 isolates, including 68 isolates from tomato and 2 isolates from potato, from six counties of Taiwan were all A1 mating type. Three tomato isolates of P. infestans caused only leaf blight of tomato, while two isolates obtained from potato were able to cause the disease both on potato and tomato, indicating that host-specific strains of P. infestans occur in Taiwan.
本報導Phytophthora infestans配對型在台灣之分佈情形及對蕃茄及馬鈴薯之病源性。共有70株分離株離自6個縣市供測定配對型，其中68株分離自蕃茄和2株分離自馬鈴薯均為配對型A1。病原性測定試驗結果為蕃茄分離菌株，只能引起蕃茄病害,然而馬鈴薯分離菌株可以引起馬鈴及蕃茄病害。上述結果顯示，在台灣存在不同寄主專一性之P. infestans菌株。
