本研究采用AFLP和SRAP分子标记技术对9个哺鸡竹类竹种(含2个变型)的亲缘关系进行分析.研究结果表明:12对AFLP引物共扩增出359条带,多态性条带比率为49.7%,相似系数变化范围在0.779~0.978之间;24对SRAP引物共扩增出258条带,多态性条带比率为64.O%,相似系数变化范围在0.721~0.958之间.UPGMA聚类分析表明,AFLP和SRAP标记均将哺鸡竹分成2大类:第Ⅰ类为富阳乌哺鸡竹、花哺鸡竹、黄纹竹、黄秆乌哺鸡竹、毛壳花哺鸡竹、乌哺鸡竹、白哺鸡竹;第Ⅱ类为云和乌哺鸡竹、红哺鸡竹.对这两种标记相似性系数进行相关性分析,AFLP与SRAP的结果呈极显著相关(r=0.934),但SRAP标记比AFLP标记可在竹类及其种下等级检测到更大的遗传变异.
本研究採用AFLP和SRAP分子標記技術對9箇哺鷄竹類竹種(含2箇變型)的親緣關繫進行分析.研究結果錶明:12對AFLP引物共擴增齣359條帶,多態性條帶比率為49.7%,相似繫數變化範圍在0.779~0.978之間;24對SRAP引物共擴增齣258條帶,多態性條帶比率為64.O%,相似繫數變化範圍在0.721~0.958之間.UPGMA聚類分析錶明,AFLP和SRAP標記均將哺鷄竹分成2大類:第Ⅰ類為富暘烏哺鷄竹、花哺鷄竹、黃紋竹、黃稈烏哺鷄竹、毛殼花哺鷄竹、烏哺鷄竹、白哺鷄竹;第Ⅱ類為雲和烏哺鷄竹、紅哺鷄竹.對這兩種標記相似性繫數進行相關性分析,AFLP與SRAP的結果呈極顯著相關(r=0.934),但SRAP標記比AFLP標記可在竹類及其種下等級檢測到更大的遺傳變異.

In this research,amplified fragment length polymorphisms(AFLP)and sequence-related amplified polymorphisms(SRAP)molecular markers were used to detect the genetic relationship among nine Puji-bamboo species,in which there were 2 cultivars,Ph.vivax f.huangwenzhu and Ph.vivax f.aureocaulis.359 bands were generated by 12 AFLP primer combinations with polymorphic bands accounting for 49.7%and similarity coefficient ranging from 0.779 to 0.978,and 258 bands were produced by 24 SRAP primer combinations with polymorphic bands accounting for 64.0%and similarity coefficient within 0.721 to 0.958.UPGMA cluster analysis indicated that the germplasms were both divided into two clusters base on AFLP and SRAP markers,cluster Ⅰ was composed of Ph.nigella,Ph.glabrata,Ph.vivax f.huangwenzhu,Ph.vivax f.aureocaulis,Ph.circumpilis,Ph.dulcis and Ph.vivax f.vivax;Cluster Ⅱ only including Ph.yunhoensis and Ph.iridescens.Correlation analysis of similarity index between the two markers showed that the significant correlation between AFLP and SRAP markers was observed (r=0.934),and SRAP was more suitable for the analysis of genetic diversity in bamboo species and infra-species.
