Study on genetic relationship of Astragalus membranaceus var mongholicus in different producing area using SRAP / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the genetic relationship of Astragalus membranaceus var. mongholicus in different producing area and provide theoretical basis for the evaluation of Astragalus germplasm resources.</p><p><b>METHOD</b>Through quence-related amplified polymorphism (SRAP) analysis, the systematic diagram of genetic relationship was constructed by UPGMA method.</p><p><b>RESULT</b>A total of 141 SRAP markers were scored. By the use of UPGMA cluster analysis with genetic distance, Astragalus could be divided into two provenance plots of Gansu and Shanxi.</p><p><b>CONCLUSION</b>The genetic differentiation among populations of A. membranaceus var. mongholicus is remarkable. SRAP marker could be efficiently used for the study of the genetic relationship of Astragalus.</p>
