Our study demonstrates that Rho is the statistic of choice for estimating genetic differentiation in polyploids.Īckerman WL (1971) Genetic and cytological studies with Camellia and related genera. The Rho statistic showed a moderate level of genetic differentiation between mountains and lower levels of genetic differentiation within each mountain. Classical genetic differentiation estimates of F st failed to discriminate genetic differentiation between and within mountains. Genetic structure analyses indicated clear genetic differentiation between the Jinggang and Lu mountains and lower genetic differentiation among altitudes within each mountain. High levels of genetic diversity were found on both the Jinggang and Lu mountains. oleifera samples were all hexaploid at various altitudes of the Jinggang and Lu mountains. The flow cytometry results indicated that wild C. Various estimates of genetic differentiation were compared. Genetic diversity and structure were analysed. Eight highly polymorphic SSRs were used to genotype the samples. The ploidy levels were determined with flow cytometry analysis. oleifera samples were collected at different altitudes on the Jinggang and Lu mountains of China. oleifera as a case study for analysing genetic diversity, structure and differentiation in polyploid plants using simple sequence repeats (SSRs). The characteristics of polyploidy may lead to considerable biases in estimates of genetic diversity and differentiation. Camellia oleifera may be predominantly hexaploid. The patterns of genetic differentiation among altitudes/latitudes in wild C. ![]() oleifera is an essential genetic resource for breeding. oleifera is the most important woody oil crop in China. Camellia oleifera is a subtropical evergreen plant. ![]()
