Genetic diversity of three wild populations of H.lilioasphodelus L. from different circuments were examined with RAPD markers.The result indicate that most of the variations exist within the populations, though divergence occur among them in some degree. The genetic diversity of the three populations was interrelated with their niche to a certain extent. The cluster analysis of the three populations revealed that the relationship among them was interrelated with their geographic distributions. 北黄花菜 遗传多样性 遗传分化 RAPD 聚类分析 Hemerocallis lilioasphodelus L. genetic diversity genetic divergence RAPD cluster analysis Q943 国家自然科学基金!（39670050） 1999-06-01 2021-04-01 6
