采用AFLP技术对豇豆属、角马亚属的代表性种质资源进行了遗传多样性分析。根据形态多样性和地理来源选择种质，包括角豆亚属21种中的18种。利用AFLP条带多态性产生的信息，估算了Jaccard相似系数和核苷酸多样性，测定了类群内和类群间的遗传多样性。这些数据也被用来生成表型图，以可视化分析的加入之间的关系。角豆属和小叶豆属组的所有种均分离。然而，大多数的sectionAngulares种显示出较高的相似性，表明低水平的遗传分化。在角豆组中，有一个种，即三脉豆（V.trinervia），与其它种分化良好，代表角豆组与角豆组其它种之间的一个独立的进化分支。本文首次利用AFLP分析数据描述了新记录种干旱卫矛V.aridicola、印度卫矛V.exilis、尼泊尔卫矛V.nepalensis和细茎卫矛V.tenuicaulis与角豆亚属其它种的亲缘关系。
A representative set of germplasm of genusVigna subgenus Ceratotropis specieswas used to analyze genetic diversity using amplified fragment lengthpolymorphism (AFLP) methodology. The germplasm was selected based onmorphological diversity and geographic origin and includes 18 out of the 21species in the subgenus Ceratotropis. Genetic diversitywithin and between taxa was measured using information generated by AFLP bandpolymorphism from which Jaccard's similarity coefficient and nucleotidediversity were estimated. The data were also used to generate phenograms tovisualize relationships among analyzed accessions. All species in sectionsCeratotropis and Aconitifoliae arewell separated. However, most of the species in sectionAngulares show a high level of similarity suggesting a lowlevel of genetic differentiation. In section Angulares onespecies, V. trinervia, is welldifferentiated from the other species and represents a separate evolutionarybranch between section Ceratotropis and other species insection Angulares. The relationships between the newlydescribed species V. aridicola,V. exilis, V.nepalensis and V.tenuicaulis and other species in the subgenusCeratotropis are described for the first time based on AFLPdata.
