基于RAPD分析的中国苏铁属部分种类亲缘关系探讨
Genetic relationships analysis in some species of Cycas in China by RAPD markers
摘要
Abstract
In this paper,333 RAPD markers obtained from 22 materials of 21 species of Cycas were analyzed with the screened 21 RAPD primers. The genetic relationships constructed with UPGMA method of NTSYS software quite showed their linage relationship. According to the result of genetic relationship and the morphological traits analysis,it's concluded that C. multifida should be a sub-species of C. segrnentifida,20 species that listed as follows:C.xilingensis, C. longlinensis, C. segmenti fida, C. acuminatissirna, C. micholitzii, C. longipetiolula, C. multifrondis, C.longiconi f era , C. guizhouensis, C. szechuanensis, C. brevi pinnata , C. miquelii , C. balansae , C. shiwandashanica , C.parvulus , C. fair ylakea , C. hainanensis , C. taiwaniana , C. guang dong snsis , C. diannanensis , should be a independent genetic units at species level.关键词
