Abstract:The genomes of 16 clones of 2 Salix species are taken RAPD test with 12 primer. It can be seen from the electrophoretogram that primer chl-1 can distinguish the two Salix species and primer Deca-4 can distinguish the 16 clones. The dendrograms are drawn after NT-SYS analyzing DNA bands in the pattern resulted from electrophoresis of amplification products of 16 clones genome with 12 primers. The result shows the classification outcome of 2 Salix species acquired by RAPD accords with that by the traditional way.
