Abstract:
Objective To analyze the genetic relationship among the different cultivars of Cornus officinalis and provide some foundation for heredity breeding. Methods A modified method of extracting total DNA from the leaves of C. officinalis was selected by improving the traditional method-CTAB, the total DNA was analyzed by RAPD; the genetic similarity correlation was calculated by SPSS 10.0 DICE method, cluster analyses were carried out using Between-groups linkage method, and the genetic dendrogram was established. Results Random primers (22 10-bp) were selected to be used for the PCR, a total of 133 bands were amplified by 12 samples, among which 75 bands were polymorphic, accounting for 56.39%. The cluster analysis indicated that: spindleform itself was one group, short pear-shape and short cylindericform clustered together, the rest longer types clustered together, which reflected the result of artificial selection in the course of cultivating. Conclusion The result keeps accordance with the biologic character and territorial distribution of C. officinalis cultivars; RAPD analysis is an assistant mean for seed breeding of C. officinalis.
