Cultivating method and application of white-foot and black-foot recessive white local goose

Abstract

The invention relates to a cultivating method and application of white-foot and black-foot recessive white local gooses. The cultivating method comprises the following steps of: selecting mutant yellow-foot and black-foot white gooses in local colored goose varieties; self-reproduction males and females; selecting yellow-foot and black-foot white individuals in later generations; expanding, testing and breeding the pure white gooses; eliminating dominant white individuals and separated other colored individuals; repeating the self-reproduction and the breeding until stable inheritance; and cultivating new varieties of the yellow-foot and black-foot recessive white local gooses. The yellow-foot and black-foot recessive white local gooses cultivated by adopting the cultivating method can be directly put into merchandise production, increase added values of down and feather, can carry out matched production with Chinese local colored gooses to achieve the purpose of protecting Chinese local colored goose varieties and can create a hybrid with other white goose varieties to directionally cultivate new varieties.

Description

technical field [0001] The invention relates to a breeding method and application of a yellow-footed, black-footed recessive white-feathered local goose.

Problems solved by technology

At present, the production of colored feather geese in southern my country is mainly based on self-propagation of this species, which leads to low added value of down (white down is expensive), and is not conducive to the protection of local breeds, which may easily lead to the germplasm of my country's unique goose species The loss of resources also limits the hybrid utilization of the southern and northern goose species (the fur color of the offspring of the hybrids of the northern white goose and the southern colored goose does not meet the needs of the white goose consumer market)
