Abstract:

The research focused on the systematical investigation of the differences between D. involucrata and D. involucrata var. vilmorniana. Based on the observations of their morphological features, two molecular markers, ISSR, AFLP were used in the research. The result showed there were some differences in their leaves while no differences were found in their flowers or fruits. By using 10 ISSR primers and 7 EcoRI/MseI primer pairs of AFLP, no marker was found between D. involucrata and D. involucrata var. vilmoriniana. From the cluster analysis, individuals of 52 D. involucrata samples and 60 D. involucrata var. vilmoriniana samples did not gather together respectively either. There seemed only some differences on their leaves. The further work should be done to find whether there are some differences between the species and its variety in molecular level.
