摘　　要：对新疆草地饲用植物霜霉菌（Ｐｅｒｏｎｏｓｐｏｒａｃｅａｅ）进行了系统的分类研究。自新疆１２４份草地饲用植物霜霉菌标本上共鉴定出６属３７种霜霉菌，分别寄生于１４科４２属６３种寄主植物，其中新种２个，新变种２个，新寄主记录１０个，国内新记录种８个。从生物多样性保护和生态系统的观点出发，对新疆草地饲用植物及其霜霉菌的分布，栽培牧草与天然草地野生植物霜霉病的发生、流行程度进行了讨论。One hundred and twenty─four specimens collected from forage plants growing at grassland regionswithin Xinjiang have been examined.Thirty seven species of downy mildews parasitizing on 63 species of42 genera of 14 plant families have been identified.Amomg them,2 new species and 2 new varieties wereproposed.Eight were new records of China and ten hosts were recorded for the first time. According to the review of biediversity and ecosystem,distribution of the downy mildews and theirhosts,disease indidence of cultivated and nativewild herbages were discussed.
