Two hundreds and fourteen isolates of Phytophthora nicotianae var. parasitica collected from rotted roots of strawberry seedlings on nursery beds in Saga prefecture were tested on the mating types, A1 or A2, by formation of sexual organs. Among them, 54 isolates were identified as type A1 and the others were as type A2. From the result of the mating type test, it was found that all isolates were heterothallic. The isolates from Saga city·Saga-gun, Kanzaki-gun and Kishima-gun were separated into type A1 and A2, whereas those from Karatsu city, Ogi-gun and Tosu city·Miyaki-gun were either type A1 or A2.
