摘要 使用扩增片段长度多态性 (AFLP) 标记评估了威尼托地区两个古老本土鸡品种的遗传多样性。使用三个选定的 AFLP 引物组合对总共 63 个个体进行了分析，产生了 66 个明确的多态性。分析的品种是 Padovana 和 Polverara（两个古老品种）以及参考肉鸡品系。不同品种之间的预期杂合度（Het）没有显着差异。 AFLP 位点的变异性在不同品种间基本保持不变，如遗传分化系数 (Gst) 值所示。 Padovana 和 Polverara 品种之间的遗传距离最小，表明它们在遗传上可能很接近。
Abstract Genetic diversity in two ancient indigenous chicken breeds of the Veneto region was assessed using Amplified Fragment Length Polymorphism (AFLP) markers. A total of 63 individuals were analysed using three selected AFLP primer combinations that produced 66 clear polymorphisms. The breeds analyzed were the Padovana and the Polverara (two ancient breeds) and a reference broiler line. The expected heterozygosity (Het) did not differ significantly among breeds. The variability at AFLP loci was largely maintained across breeds, as indicated by the coefficient of genetic differentiation (Gst) value. The lowest genetic distance is found between the Padovana and Polverara breeds suggesting that they could be genetically close.
