The ISSR fingerprinting of 18 Japanese plum cultivars and 12 plum species or variety were established by using optimum system with primer 5"-9T-3"and 5"-9C-3", respectively. The identification rate of plum cultivars and species or variety was 100%. The effects of five important components on reaction of SSR were studied with Prunus salicina cv. Meilili. The results showed that the optimum concentration of five important components i.e. Tag DNA polymerase, Mg +, single primer, template DNA and dNTPs in 25 μL reaction system of SSR were 1.5u, 2.0mM, 0.8 μ M, 30~40ng and 0.16~0.24mM, respectively. The dendrograms of these cultivars was contructed according the Jaccard coefficient of similarity.

利用该优化体系，以5′-_9T-3′为引物，构建了中国李18个品种的ISSR指纹图谱，该引物可将这些品种完全区别开来；以5′-_9C-3′为引物，构建了李属6类种质资源的ISSR指纹图谱，该引物区分率为100％。4、中国李品种适宜的SSR反应分析体系是：25μL SSR反应体系中，Taq DNA聚合酶、Mg~(2+)、每个引物、模板DNA和dNTPs等5种成分的适宜浓度分别是：1.5u、2.0mmol·L~(-1)、0.8μmol·L~(-1)、30～40ng和0.16～0.24mmol·L~(-1)。5、采用RAPD、ISSR和SSR等三种分子标记技术对中国李品种资源54份和2个欧洲李品种进行了遗传多样性分析，并以品种间的遗传相似系数构建了Jaccard聚类树状图。

The primers and the detection programs have been used to detect the pathogens in the inoculated-diseased cucumber plants .The details are reported as follows: 1. By using the primers ITS1/ITS4, only Fusarium isolates could be amplified to produce a special fragment of 750bp. This product generated 480bp, 200bp and 100bp fragments after digested by restriction enzyme HinfⅠonly from the pathogen of Cucurbits Fusarium Wilt.

引物ITS1/ITS4只在镰孢属菌株上扩增到一条750bp分子片段，其他供试菌株无扩增条带产生，扩增产物经HinfⅠ酶解后，只有瓜类尖镰孢菌产生480bp、200bp和100bp 3条带，说明该PCR-RFLP程序对瓜类尖镰孢菌具有特异性；巢式PCR引物BIK1/BIK4和BIK2/BIK3只有在黄瓜尖镰孢菌菌株上扩增到一条800bp分子片段，其他菌株均无扩增条带产生，说明该巢式PCR程序对黄瓜尖镰孢菌具有特异性。
