EVALUATION OF GENETIC DIVERSITY FOR Chrysanthemum spp. IN SOUTHERN VIETNAM
Abstract
Molecular markers play increasingly important roles in classification and identification of plant varieties. In this study, ten RAPD markers were used to investigate genetic diversity of 12 colleted samples belonging to Chrysanthemum spp. The obtained results showed that the coefficient of genetic similarity of Chrysanthemum spp. samples ranged from 0.64 to 0.86. All of the used primers generated high polymorphism with an average of 25.6 bands per primer, of which a total of 27 specific polymorphic bands can be used to distinguish different Chrysanthemum species at molecular level. The result of this study can be used as a scientific basis for breeding Chrysanthemum spp. varieties as well as genetic conservation.
