The dendrogram from RAPD markers supported that Shantao was in an independent group. 5. Core germplasm in each deme was put forward and listed as Liemage, Haluhong, Bailey, Akelawa in rootstock group; Hongchongban, Shouxintao, etc.

采用ITS序列重建系统发育树，陕甘山桃和山桃为并行分支，各自成为独立一组，位于桃、新疆桃，光核桃、甘肃桃的基部。

Using RAPD markers, delving and clearing the genetic relationships of partly Pyrus germplasm was studied, by the existent demurral and the dendrogram.

本研究利用RAPD分子标记技术，通过聚类分析和遗传相似系数分析，对其进行分类研究。

The decomposition of chromosome was a main problem in construction of BAC library. DNA discompose would be avoided or decreased by adjustments of component and pH of chromosome extraction buffer or pre-electrophoresis for 6-8h before digestion. Identification of inter-species hybrids was a necessary step for creating a new germplasm. Two samples were selected from offspring of hybridization and backcross of a cross between cabbage and Chinese cabbage.

鉴定种间杂种是利用远缘杂交创造新种质时的一项重要工作，本研究运用细胞核DNA含量流式测定技术，对甘蓝和白菜杂交及回交各世代的DNA含量进行检测，以监控遗传物质在不同材料间的流向，并从回交二代植株群体中筛选了两个材料，具有和白菜差异不显著的DNA含量，可推断其为核质杂种。

Our group collected 35 accessions in dooryard from 13 Provinces and 34 accessions from three germplasm repositories.

本课题组收集了13个省市的35份枳资源，各资源圃的枳选系34份共69份材料建立起全国最大的枳资源收集圃。

Variation existing between accessions from dooryard and from germplasm repositories manisfested that there still exists quite a lot genetic diversity out of germplsam repositories.

野外收集的枳资源与从各资源圃收集的资源包含的遗传变异有较大的差异，表明种质圃外资源还包含较丰富的遗传多样性。

In addition, 11 mutants were also chosen form a commercial nursery. The main results are as follows: 1. It was the first time to conduct research on the germplasm innovation of Dracaena cambodiana.

首次对海南龙血树进行了种质创新途径的研究，田间自然变异的选择是目前最为有效的途径，组织培养分别结合EMS、60Co辐射和秋水仙素的诱变途径也是有效果的。

It was showed that from a super-high yield germplasm HS Z6-06-56 derivated from an interspecific hybridization between common wheat and durum wheat: Dates of flagging,heading and maturing were 1,1 and 2 d earlier compared with its accepter′s parent of Shi 4185,respectively,there were no differences between traits of plant height,head length,spikelets/head by means of anova analysis.

通过对普通小麦、四倍体硬粒小麦种间杂交超高产新种质HS Z6-06-56性状表现分析表明：该种质与受体亲本石4185相比，挑旗期、抽穗期及成熟期分别提早1，1及2 d，株高、穗长、小穗数三性状等同于受体。

Among above mentioned germplasm, Yulupantao, Qiumi, Elberta, Fertinimoroteini appeared very special because of both RAPD markers and clustering place in dendrogram.

以上种质中，玉露蟠桃，秋蜜、爱保太和佛尔蒂尼莫蒂尼无论从带型还是在聚类图中的位置表现为更为特殊。

In conclusion, a comprehensive analysis of water lilies based on morphological and molecular data was performed, showing the phylogenetic relationships among the 10 genera and providing new evidence for classification at family level. The specific and infraspecific relationships within the genus Nymphaea were revealed using the ITS sequences, providing a new approach to germplasm identification and phylogenetic analysis of water lilies. The investigation of invasive fanwort in China may also provide a sound basis of its ecological studies.

总之，本文以国内外长期研究为基础进行了综合定量的形态学与分子序列分析，明确了10个属的系统位置，为科的划分提供了新的依据；通过运用ITS序列研究睡莲属的种及种下单位之间的亲缘关系，为睡莲类植物的种质资源鉴定提供了新的工具；对水盾草进行了初步的调查分析，为今后深入开展其生态学研究打下了良好的基础。
