Genetic diversity of Curcuma comosa Roxb. revealed by DNA and mophological markers

Abstract

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.
