采用等位酶电泳技术研究了云南省中北部昆明、富民、宾川3县（市）及四川省西南布拖县的硬枝野荞麦（Fagopyrum urophyllum）6个天然居群的遗传多样性和分化。硬枝野荞麦居群内维持有较高的遗传多样性，多态位点比率为50.0%，预期杂合度和观察杂合度分别为0.251和0.471。并对硬枝野荞麦（F. urophyllum）与栽培荞麦之间遗传变异作了比较。

Based on allozyme electrophoresis, the genetic diversity and differe-ntiation among 6 wild populations of Fagopyrum urophyllum from the counties Kunming, Fumin and Binchuan in the north-central part of Yunnan Province, the county Butuo in the southweast part of Sichuan Province, China, were studied in this paper. The results showed that the genetic diversity within wild population was high. The percentage of loci polymorphism (P) was 50.0%, the means of expected and observed heterozygosities were 0.251 and 0.471, respectively. The genetic variation between cultivated buckwheat and wild population was compared.
