| Abstract: | In order to analyze the genetic diversity of C. magnocarpa in Teng county of Guangxi, 14 samples were marked using molecular marker, and the results of molecular marker were analyzed by NTSYSPC2.1 software. The results show that: 5 primers were used for DNA amplification of 14 samples, and 38 bands were amplified, among which 37 bands were polymorphic bands, and the polymorphism ratio was 97.37%. The genetic distances of samples ranged from 0.3952 to 2.1383, of which the largest genetic distance between 3-5 and 1-12 was 2.1383. The smallest genetic distance between N3 and JJ5 was 0.3952. Therefore, the C. magnocarpa germplasm possess a higher level of genetic diversity, and genetic differentiation is significant. |
