[Method]The genetic diversity of 22 new oil palm germplasm from Hainan and Yunnan were analyzed by ISSR technique. [Result]A total number of 201 bands were amplified with 23 ISSR primers,and polymorphic bands accounted for 41.8%. 22 oil palm varieties were divided into two groups by cluster analysis:Group I included new varieties of R1-R12 from Hainan and V20 from Yunnan,while group II included new varieties of V13-V22 from Yunnan,except V20. [Conclusion]New breeding oil palm germplasm from Hainan and Yunnan may come from different countries or regions.展开更多
