摘要
采用AFLP和形态标记技术研究了万泽姜黄(Curcuma comosa Roxb.)的遗传多样性。姜黄样品33份。9个Eco RI - Mse I引物组合共扩增出161条条带，其中102条为多态性条带，占总数的63.35%。从AFLP得到的UPGMA聚类可以分为两大类。主坐标分析(PCoA)的结果与树形图中的分组一致。相似系数取值范围为0.49 ~ 1.00。形态特征也可分为两大类，各有不同的花序。
Genetic diversity of Curcuma comosa Roxb. revealed by DNA and mophological markers
AFLP and morphological markers were applied to study genetic diversity of Waan Chak Modlook ( Curcuma comosa Roxb.). Thirty-three samples of Curcuma comosa Roxb. were amplified with nine Eco RI– Mse I primer combinations that generated a total of 161 bands, in which 102 of them or 63.35% of total bands were polymorphic. The UPGMA clusters derived from AFLP showed that they could be classified into two major groups. Principal coordinates analysis (PCoA) was also analyzed and the result was consistent with the grouping found in the dendrogram. The values of similarity coefficient ranged from 0.49-1.00. Morphological characteristics could be also classified into two major groups with different inflorescence.
