It is well known that many Chinese goose breeds differ substantially in economic performance, but the genetic changes involved are still poorly understood. This study sequenced 35 individuals from four goose breeds namely Shitou, Zhedong White, Taihu, and Zi with an average sequencing depth of 10× for each individual. Among these populations, SNPs were identified, which clustered the individuals into four distinct genetic groups in accordance with the four breeds. Genomic comparisons among the four goose breeds revealed many candidate genes, as well as pathways that may be associated with meat yield in Shitou geese and laying traits in Zi geese. These findings will enable a better understanding of the artificial selection history of Chinese local geese and provide a valuable resource for future research on the breeding of geese for the economic traits of meat and egg production.
众所周知，许多中国鹅品种在经济性能上有很大的差异，但涉及的遗传变化仍知之甚少。本研究对来自四个鹅品种（石头鹅、浙东白鹅、太湖鹅和籽鹅）的 35 个个体进行了测序，每个个体的平均测序深度为 10×。在这些群体中，鉴定出了 SNPs，这些 SNPs 将个体聚类为四个不同的遗传群体，与四个品种相对应。对四个鹅品种的基因组比较揭示了许多候选基因以及可能与石头鹅产肉量和籽鹅产蛋性状相关的途径。这些发现将有助于更好地了解中国地方鹅的人工选择历史，并为未来研究鹅的经济性状（肉和蛋生产）的育种提供有价值的资源。
