%X The systematic relationship has been quite confused among the species of <em>Larix</em> because of given the weak morphological differentiation between species. The phylogeny of <em>Larix</em> is still poorly known. The genetic structures of 5 species of <em>Larix</em> were analyzed in this paper. Using horizontal sliceable starch gel electrophoresis method, the variation at 8 allozyme loci coding for 5enzyme systems(AAT, IDH, DIA, PGM, SKDH) was examined in 5 species of <em>Larix</em> taxa across their range in current study. These species are <em>Larix sibirica</em> Ledeb, <em>L. cajanderi</em> Mayr, <em>L. gmelinii</em> Rupr, <em>L. sukaczewii</em> Dil and hybrid <em>L. czekanowskii</em>(<em>L. gmelinii</em>&times;<em>L. sibirica</em>). The result showed that the genetic distance of the 5 species of <em>Larix</em> is from 0.067 to 0.260, which was higher than that of intra-specific populations. The result also revealed the relationship between the 4 species Considering the morphological, biological and ecological characteristics of the 5 <em>Larix</em> species, the evidence of allozyme variability support the idea that <em>L. cajanderi</em>, <em>L. gmelinii</em>, <em>L. sibirica</em> and <em>L. Sukaczewii</em> are independent species.
