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 identification of tea plant resistance to tea brown blight The resistance of 13 tea plant cultivars to tea brown blight had the difference or remarkable difference. In general, the resistance of big leaf cultivars was relatively weaker, the resistance of middle leaf cultivars was relatively stronger.

茶树品种抗云纹叶枯病的鉴定 13 个茶树品种对茶云纹叶枯病的抗性存在显著差异,一般大叶种材料的抗性较弱,中叶种材料的抗性较强。

Biological characteristics of the pathogen and the resistance of 13 cultivars of tea plant to tea brown blight were studied by means of natural infection in the field and artificial inoculation in vitro. Resistant cultivars and susceptible cultivars of tea plant were divided. And the resistance mechanism was researched tentatively. The findings are as follows: 1 Some biological characteristics of the pathogenic fungus The experiment result showed: the optimum temperature for the growth of fungus mycelium was from 24 to 27℃, the optimum temperature for sporulation ranged 22 to 30℃. Treated at 54℃ in 10 minutes, the spores didn't germinate. The optimum pH for the growth of the mycelium was 5.1~5.9, the optimum pH for sporulation ranged 5.0~6.0. Light had no much effect on the growth of fungus mycelium, but had much effect on the reproduction of the spore.

The nine tested tea cultivars were categorized into three groups by cluster analysis according to the number of probes per insect, waveform durations, or duration per probe including various waveforms on different tea cultivars. Waveforms S, E and F correlated to the main feeding activity of the leafhoppers and may provide valuable information on predicting the resistance levels of the tea plants to the leaThopper. The resistance level of the nine tea cultivars to the leafhopper was ranked based on the durations of waveform S, E and F, as well as the duration every probe including various waveforms.

以该叶蝉在不同品种茶树上的平均刺探次数和各波形平均持续时间为指标,或者以其在不同品种茶树上含有各波形的单次刺探平均持续时间为指标,分别进行聚类分析,均将9个品种分为3个不同的组。S、E和F波对应着假眼小绿叶蝉在茶树上的主要取食活动,可能与茶树抗假眼小绿叶蝉的取食密切相关。
