Four primers screened from 17 primers were used to analyze genetic diversity between one population in the mine deposits and one in noncontaminated soil, the results showed that a higher level of DNA diversity was detected in the plants grown in the mine deposit. The results above indicated that Commelina communis grown in copper mine deposits had evolved adaptation under heavy metal stress, and such adaptation had a geneic basis.

从17条引物中筛选出4条对其中1个铜矿山种群和1个正常土壤种群进行种群内的遗传多样性研究，结果显示污染种群内基因遗传多样性水平高于未污染种群，上述结果说明了在铜胁迫下矿山鸭跖草种群已经进化了对铜污染的适应性，并且较高水平的遗传多样性可能是植物适应重金属污染胁迫环境的基础。

The results showed that the clonal reproduction was preponderant, but it has still a high genetic diversity (Ho=0.7148). At the same time, Corylus heterophylla Fisch genetic individual was found. A single cluster was basically a genetic individual; adjacent clusters were basically the same genotype and clonal reproduction has larger percentage.

结果表明：平榛虽然克隆繁殖占有优势，但仍具有较高的遗传多样性(Ho=0.7148)；同时确定了平榛的遗传个体，同1株丛内个体基本上为1个独立的遗传个体，相邻的株丛个体基因型基本一致，克隆繁殖比率较大。

The results demonstrated that the offspring plants had certain genetic diversity. The pink and the nacarat/saffron plants had the highest genetic diversity. When RP1 or R01 as father or mother was crossed with the other color varieties, their F1 populations had significant segregation chromatogram.

对RP1的49个子代个体，R01的123个子代个体，进行ISSR遗传多样性分析及主成份分析，子代个体间存在一定的遗传差异，其中仍然以表现粉色及桔黄/桔红色的个体遗传多样性最丰富。

The method of PCR-analyzed microsatellites can be used for distinguishing between inbred and outbred、different strains、strain and substrain.and it provides a lot of information for genetic mapping,gene location and heredity probe of the inbred rat strains,and a speedy、convenient method for genetic research of the inbred rat.

因此，本实验为开展近交系大鼠遗传作图、基因定位和为实验动物的遗传背景监测提供可靠的信息，为大鼠遗传基因的研究提供了一个快捷简便、特异准确的方法。

The phenotypic variation coefficients of most of the traits decreased with the advances of generation of selection.

群体内的遗传多样性大于群体间的遗传多样性，且群体内的遗传差异随着选择的增加呈下降趋势。

Results (1) From more than 100 primers, 11 primers producing polymorphism and reproduceable bands were selected, 129 bands were amplified.(2) The percentage of polymorphic bands within different populations were 20.9%-55.0%.(3) The cluster map including all samples were obtained by UPGMA. In the map, there were six cluster groups and three individuals outside the groups. The branch with five samples of Zhongjiang Sichuan population were far from other samples in genetic distance.(4) According to the distribution provinces five groups were divided in genetic variance analysis. Genetic variance 80.44% existing within population, 8.29% among populations and 11.27% among groups.

结果 （1）从100多个引物中选择出11个多态性强和重复性好的引物，扩增得到129条带；（2）不同居群内多态位点比率为20.9%－55.0%；（3）用UPGMA法得到所有样本的聚类图，可分为6个主要分支组和3个组外个体，其中四川中江居群的5个样本聚为一组，并与其他样本遗传距离较大；（4）按产地分组，遗传差异的80.44%存在于居群内，8.29%来自于组内居群间，11.27%的遗传差异来自于组间。

A dendrogram constructed by an unweighted pair group method of cluster analysis showed that populations from Panan constructed one branch and separated from other populations.

根据POPGEN软件计算得到的群体之间的遗传距离进行聚类分析，结果显示浙江的各栽培群体有较近的遗传关系，与其他群体已存在遗传分化。

The results demonstrate that,(1) The average genetic value of the sires of bottom-up scheme are higher than that of conventional progeny-test by 10%, the bulls that enter progeny-test by 55%, and the cows by 6%.
