Results It was able to analyze the DNA polymorphism using 15 polymorphic microsatellite loci between Macaca mulatta and Macaca irus. The allele numbers were more than 7, and there were differences in 11 allele numbers between the two groups.

结果 筛选的15个具有显著多态性的微卫星DNA位点对恒河猴和食蟹猴种群可以进行DNA多态性分析，其等位基因数目均在7个以上，且两群体间有11个位点的等位基因数存在一定的差异。

Methods The DNA polymorphism was analyzed in 50 individuals of Macaca mulatta and 50 individuals of Macaca irus using 15 PCR-microsatellites DNA loci and the differences of allele numbers between those two species were compared.

利用聚合酶链反应扩增技术采用15个多态性微卫星DNA位点对50只恒河猴和50只食蟹猴个体进行了DNA多态性的分析，对比两群体间等位基因数目差异。

Percent and 21. 4 percent respectively. F1 plants of R01 self-cross also present diverse colors such as white, pink, red, nacarat/saffron, dark yellow, yellow and so on, And the pink and the nacarat/saffron plants have the highest proportions, 50.6 percent and 31. 4 percent, respectively. The wide segregation chromatogram of self-cross progeny implies that these two varieties themselves contain the abundant genetic polymorphism. The ISSR genetic diversity analysis and the principle factor analysis were performed using 49 plants of RP1 self-cross progeny population and 123 plants of R01 self-cross progeny population.

RP1及R01的遗传多样性最高，这从自交一代的表观性状及ISSR的遗传变异可以得到证实，如RP1自交，F1代花色有白色、粉色、玫瑰红、深红色、桔红/桔黄、黄色，黄红复色等，其中以粉色及桔红/桔黄色占的比例最大（分别占61.2％，21.4％）；R01自交，Fl代花色有白色、粉色、红色、桔红//桔黄、深黄色，黄色，其中以粉色及桔红/桔黄色占的比例最大（分别占50.6％，31.4％），较广的自交分离色谱，表明两个品系自身存在丰富的遗传多态性。
