F×S = Putian White×Shan Ma; S×F reciprocal cross. P×S = Putian Black×Shan Ma; S×P reciprocal cross.

Ma = Duckling’s down pattern and color similar to that of the Shan Ma duckling. Black = Duckling down of extended black color.

White = Yellow down color and white adult plumage. Multicolored = Undefined color pattern.
