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.
