摘　　要：通过对四川3个州和3个地区共60多个县的野生荞麦资源进行系统考察、搜集和整理,搜集到分布于四川不同生态环境的野生荞麦8个种、2个变种和2个亚种种质资源313份,植株标本172份,明确了四川野生荞麦资源的种类、特征特性、原生境的多样性和两个主要分布中心,发现了小籽粒草质状硬枝万年荞和红花硬枝万年荞,F.x、F.y和F.z的植物学特征与已命名种不尽相同,可能为新种或新变种(待定)。After systematically investigating and collecting the wild buckwheat resources of more than 60 counties in 3 states and 3 areas of Sichuan,313 resources and 172 samples of 8 species,2 varieties,and 2 subspecies distributing different ecological areas were collected. The types,characteristics,primitive environmental diversity and two main distribution centers of wild buckwheat resources were defined in Sichuan,miniplasmids grassy F. urophyllum and red-flowercd F. urophyllum were discovered the botanical features of F. x ,F. y and F. z were not the same as the named-species,which were likely to be new species or varieties （undetermined）.
