Genetic Analysis of Superior Clones and Identification of Specific Marker of Elite Clones of Pinus kesiya

摘要

In the present study, the genetic distances between 85 superior clones from seven natural populations of Pinus kesiya var. langbianensis were analyzed by RAPD-PCR assays, and then, a UPGMA cluster diagram was established based on the genetic distances to reveal their genetic relationship. In addition, specific markers of elite clones were identified by carefully comparing the fingerprints of the 85 clones. The results showed that the 85 P. kesiya clones were divided into three groups at a genetic distance of 0.59. Two specific markers that were able to distinguish some elite clones from others were identified. The results may provide a molecular basis for the identification and selection of elite clones of Pinus kesiya var. langbianensis.
