| 摘 要： | 应用AFLP 技术, 用8 对引物对20 株小金海棠家植实生群体进行遗传一致性分析。结果表明,小金海棠实生群体内具有高度的遗传一致性, 遗传相似系数为98. 92 %; 1. 08 %的遗传差异可能是由于有性杂交的基因重组导致差异片段出现所造成的。

| Abstract: | AFLP was applied in this experiment to detect the genetic identity of Malus xiaojinensis from natural population. The fingerprinting of 20 seedlings of M.xiaojinensis with 8 pairs of primers showed that M.xiaojinensis in natural population had a high degree of genetic identity, its genetic similar coefficient being 98.92%. Genetic difference also existed in this population, 1.08%fragments were different fragments. The patterns analysis indicated that these different fragments were resulted from gene recombination of sexual hybridization. |
