The endosperm DNA samples of the seeds of a same individual plant of eight main cultivars (clones) of Torreya grandis are analyzed with RAPD technology by using 23 primers that have distinct polymorphism?The result indicated that there was a relatively large difference between the eight varieties at the level of DNA molecule; the marker genotype of varieties was established according to particularly isolated bands in the experiments; the clone varieties of Torreya grandis can be identified at the level of DNA molecule according to the marker genotype; the eight varieties of Torreya grandis wer...
