[Method] The primers which produced polymorphic and bright DNA bands were selected to construct the DNA molecular fingerprint map for 77 major hybrid rice cultivars approved by Hunan Province. [ Result] A total of 48 SSR primers were selected. Every cultivar had its unique fingerprint map so that the obtained data could identify differ- ent hybrid rice cultivars. [ Conclusion] This study made great contributions to the perfection of hybrid rice germplasm identification.展开更多

[ Method ] Fingerprinting patterns of the SSR markers for 33 loquat varieties in national loquat germplasm resource garden were constructed by specifically amplifying palymorphism from 7 pairs of primers screened from 51 pairs of primers of the relatives Mains and Pyrus. [ Result ] The results showed that the uses of 7 primers, namely, Hi01d05F, Hil2iO4F, CH02B10F, Hi03a03, Hi03e04, Hi04a05 and Hi02c07 could distinguish 33 loquat germplasms from one another completely. [ Conclusion] This study provides an essential criterion for classification and identification of the loquat resources.展开更多
