Abstract: Random amplified polymorphic DNA (RAPD) markers associated with phenotypic characteristics were used to analyze the genetic variation of 270 individual samples from six natural populations of Larix gmelinii (Wuyiling,Ganhe,Kuduer,Nenjiang,Moerdaoga,and Aershan). From 450 primers,23 clear RAPD primers were selected as their amplified bands with high polymorphism. The analysis included the gene diversity index,Shannons diversity index (SI),Neis gene diversity index,a cluster analysis,and a correlation analysis. Results showed 182 loci among a total of 186 were polymorphic or a percentage of polymorphism (PPB) of 97.9% having a range of 87.10%-94.09%. The gene diversity index was 0.374 3,and the genetic diversity within populations was 0.051 7 indicating that genetic variation was mainly within the population (86.19%). Mean SI was 0.482 1,and the mean for Neis index was 0.322 6. The cluster analysis revealed six populations divided into three groups (the Xiaoxingan Mountain Range,northwest of the Daxingan Mountain Range,and south of the Daxingan Mountain Range) with a genetic distance of 0.09. Genetic distance was significantly and positively correlated with geographical distance(P<0.05,r=0.768). Growth traits of the four L. gmelinii populations were 10.25%-20.78% for height,14.93%-28.37% for diameter,and 35.03%-74.36% for volume coefficients of variation. Compared with the genetic variation of breeding populations,in natural populations PPB was 5.32% greater,mean of effective alleles numbered 1.13% greater,Neis index was 4.94% greater,SI was 5.68% greater,and the populations total genetic variation 8.78% greater.[Ch,3 fig. 6 tab. 10 ref.]
