摘　　要：本文较全面地综述了马铃薯晚疫病菌的交配型、生理小种及其对甲霜灵的敏感性等表现型群体遗传结构特征的研究进展,阐述了世界各国晚疫病菌交配型的分布、生理小种组成及病菌对瑞毒霉抗性菌株的出现频率。同时综述了几种分子标记,如mtDNA指纹、RFLP、RAPD、AFLP和SSR在研究晚疫病菌基因型及遗传多样性方面的应用及研究成果。并指出了中国今后对马铃薯晚疫病菌研究工作的重点。　Phenotypic characteristics of Phytophthora infestans population,such as mating type,physiological race and metalaxyl-sensitivity were reviewed.The distribution of A2 mating type,physiological race structure and the frequency of resistant isolate to metalaxyl in different countries were described.Research results about the genotype and genetic diversity of P.infestans with the molecular markers including mtDNA fingerprint,RFLP,RAPD,AFLP and SSR were discussed.The research focus of potato late blight pathogen in China was suggested.
