| genetic structure of oryza rufipogon griff. in china. | oryza rufipogon griff. (common wild rice; cwr) is the ancestor of asian cultivated rice (oryza sativa l.). investigation of the genetic structure and diversity of cwr in china will provide information about the origin of cultivated rice and the grain quality and yield. in this study, we used 36 simple sequence repeat (ssr) markers to assay 889 accessions, which were highly representative of whole germplasm in china. the analysis revealed a hierarchical genetic structure within cwr. first, cwr ha ... | 2008 | 18827837 |
| microsatellite analysis of genetic diversity and population genetic structure of a wild rice (oryza rufipogon griff.) in china. | genetic diversity and population genetic structure of natural oryza rufipogon populations in china were studied based on ten microsatellite loci. for a total of 237 individuals of 12 populations collected from four regions, a moderate to high level of genetic diversity was observed at population levels with the number of alleles per locus ( a) ranging from 2 to 18 (average 10.6), and polymorphic loci ( p) from 40.0% to 100% (average 83.3%). the observed heterozygosity ( h(o)) varied from 0.163 t ... | 2003 | 12845446 |
