Abstract: 33 carcass traits and 7 feather-down traits of 123 Wanxi White goose×Sichuan White goose have been mensurated. By factor analysis, 12 common factors were distilled, which could explain 82.24% of the variance of 40 traits. The results showed that meat power factor, eviscerated yield percentage factor, and leg muscle percentage factor of 12 common factors indicated meat-yield capability which could explain 36.53% of the variance; fatty acid quality factor, fat power factor, and meat water loss factor structured meat quality explaining 18.34% of the variance; feather and down characteristic was composed of feather and down power factor, down quality factor, and down hydrophilicity factor explaining 15.75% of the variance; and feather type factor, heart function factor, and digestion factor made up of assistant ability explaining 11.61% of the variance.
