摘要： Survival and germination of overwintering oospores of two strains from Gansu, China compared with two standard from Wageningen, the Netherlands of Phytophthora infestans were determined in 2010-2011. It was found that compatible mating strains of P. infestans A1 and A2 produce oospores abundantly in paired cultures on tomato-rye agar medium. The survival rate of overwintering was ranged from 19.57% to 24.59%. The germination rate of overwintering was ranged from 3.58% to 8.49%, and there were no significant differences in germination rate of oospores between alternating light at day/night and whole darkness at day/night. Furthermore, the soil extract liquid was more suitable for oospore germination than distilled water.
