Abstract: RAPD is taken to study the relationship of larches in Northeast of China.41 primers are selected from 100 primers.120 Loci show polymorphism.UPGMA is taken to calculate the genetic distance within and between populations.Systematic tree is constructed.The results prove that there is difference between larches in Daxingan Mountain, Xiaoxingan Mountain, and larches in Changbai Mountain.But the genetic distance between them doesn't reach the standard of species.It is more reasonable to regard larches in Changbai Mountain as a variaty of Larix gmalinii namely, Larix gmelinii var.olgensis Ostenf.et syrach larsen.

Key words: Larch, RAPD, Genetic distance, Larix gmelinii, Larix olgensis
