French and Asian subsets of chicken breeds were first analysed using 22 microsatellites and then compared to the AVIANDIV European set using 14 loci. Positive correlations were observed between F(IT) or F(ST) and typological values or variance of markers using the multivariate analysis mcoa. The first axis of the multivariate representation separated Asian from European breeds, revealing breeds with Asian ancestor. Using all or 14 loci, correct assignation rate was always higher than 93%. The Weitzman index and the aggregate diversity D were calculated using 22 loci within French and Asian breeds. The French breed Coucou de Rennes and the Hua-Tung breed seemed to contribute the most to the global diversity of each subset. This approach on French-only breeds and then on French with AVIANDIV domestic breeds (14 loci) showed that the Marans breed contributed the most. The AVIANDIV framework could be useful to evaluate the genetic diversity of local breeds and to help in connecting national and regional conservation policies.
首先使用22个微卫星对法国和亚洲鸡种子集进行分析,然后使用14个基因座与AVIANDIV欧洲数据集进行比较。使用多变量分析mcoa观察到F(IT)或F(ST)与类型学值或标记方差之间存在正相关。多变量表示的第一轴将亚洲品种与欧洲品种分开,揭示了具有亚洲祖先的品种。使用全部或14个基因座,正确分配率始终高于93%。使用法国和亚洲品种内的22个基因座计算了韦茨曼指数和总多样性D。法国品种雷恩库库和华东品种似乎对每个子集的全球多样性贡献最大。这种仅针对法国品种,然后针对法国与AVIANDIV家养品种(14个基因座)的方法表明,马朗斯品种贡献最大。AVIANDIV框架可能有助于评估地方品种的遗传多样性,并有助于连接国家和地区的保护政策。
