The other two groups are longan and'Longli, a special germplasm', which is a natural hybrid of litchi and longan. The results from RAPD analysis also showed that longan might be the maternal parent and the extremely early maturing litchi types be the paternal parent since'Longli'is closer to longan in the taxnomy. This information would be useful in the distant crossing breeding to fruit of Sapindaceae family.

根据RAPD分析揭示的多态性水平和聚类分析结果及马贵荔×焦核三月红的F〓杂种群体表现出的广泛分离和父本特有RAPD位点分离方式的偏态性，本研究对荔枝的分类学提出新见解，认为广东的三月红、云南的褐毛荔等极早熟荔枝类型（在广州于5月20目前成熟）在分类上可自成一类，其地位应提高到&变种&一级。

利用水稻功能基因SSR 标记鉴定水稻种质资源。

Low resolution was obtained in genetic variation investigation of different cowpea cultivated germplasm of Vigna unguiculata based on ITS sequence data, while good results could be obtained in genetic diversity and phylogeny of differern species of genus Vigna.

RAPD可以用于种下的遗传多样性研究。但基于随机引物的RAPD-PCR扩增，受实验中各种因素的影响较大，导致数据获得的重复性不是很好、且不可移植。因此只能作为一种辅助方法。从技术上讲，为保证实验条件的一致性，应该一次PCR反应中对所有的研究对象进行扩增，并在扩增片段的电泳分离检测时尽量保持条件的一致。
