SSR molecular markers were widely applied in soybean researches due to its codominance,highly polymorph,abundance with random distribution in soybean genome,etc.

Therefore,in order to protect Rosa resources,conserve genetic diversity and classify different rose species,this research continued for three years and focused on the investigation,evaluation on the wild and cultivar Rosa resources,as well as their genetic relationships by using phenotypic,palynology,SSR molecular markers and nrITS sequence processes.

To overcome the limiting factors in the commercialization of the existing rapid purity identification system of hybrid rice seeds by using SSR markers,the studies were conducted on the improvement of the technology system in the aspects of DNA extraction,PCR amplification procedure and gel electrophoresis.

14 phenotypic traits and 14 polymorphic SSR markers were used, to evaluate a subset of 481 lentil accessions randomly sampled from the National Gene Bank on their genetic diversity.

Genetis analysis and SSR markers on fertility restorer gene of male sterility of wheat with Aegilops kotschyi cytoplasm;

The results showed that the identification of three methods were consistent,no significant difference,so the method of the purity identification by SSR markers was accurate,reliable,fast and could be used in purity test for hybrid rice seed.

Establishment of DNA Fingerprinting with SSR for Y58S and Some Other Elite Parents of Two-line Hybrid Rice;

Genetic Structure of Natural Populations of Liriodendron Chinense Revealed by SSR Markers;

The hybrids were validated based on morphological traits and SSR markers.
