Abstract:
Taking 42 Phytophthora capsici collected from the different areas in Qinghai province as materials,the mating types of causal organism of pepper were inspected by direct pairing.The results showed that 14 of all causal organisms were found to be A1 mating type and the A2 mating type 26，the other was A0 mating type.Accounted for 33.3%，61.9% and 4.8% of the total number of tested strains.No other mating type of Phytophthora capsici was found.Phytophthora mating type was not equilibrium distribution in Qinghai.The A2 mating type occupied a dominant position.
