Abstract: 123 geese were clustered using between-groups linkage based on 12 common factors of 40 goose carcass and feather-down traits and divided into 6 groups. By analysing difference among groups, productivity of Wanxi White goose×Sichuan White goose were estimated. The results showed that the difference among groups was significant while all geese were divided into 6 groups. The factor scorings of meat power, feather-down power, and eviscerated percentage were higher in group 1 and group 2, which indicated that geese in group 1 and group 2 had a superiority in meat-and feather-yield capability, and had lower fat, better meat hold-water capability, and lower down hydrophilicity. The factor scorings of fatty acid quality, fat power, leg muscle percentage, meat water loss, digestion, heart function, down quality, and down hydrophilicity were higher in group 5 and group 6, which indicated that geese in group 5 and group 6 had a preponderance in goose meat and down quality, and had leg muscle upgrowth, fatness, and lower hold-water capability. Group 3 and group 4 had higher factor scoring in freather-type, and other factor scorings were middlebrow.
