Method for breeding two-point-pattern lacy duck new breed

Abstract

The invention relates to a method for breeding a two-point-pattern lacy duck new breed. The method comprises the following steps of: 1) selecting Sichuan lacy ducks as materials and inbreeding two generations, wherein the Sichuan lacy ducks are hybridized by white feather Tianfu meat male ducks and Sichuan local female sheldrakes; 2) hybridizing male ducks obtained in the step 1) with female cherry valley ducks to generate hybrid lacy ducks, performing appearance selection for three generations, and building the hybrid lacy duck F1 generation by the remained individuals; 3) performing early breeding on the hybrid lacy duck F1 generation by using a molecular marker of an MC1R gene; 4) performing family breeding on the obtained remained individuals and performing closed breeding to generate F2 generation; and 5) hybridizing the F2 generation individuals with Aobaixing Duck or Beijing ducks to generate the lacy ducks with a small amount of black feather on the heads and the tails. The method has the advantages that: hybrid combination is performed on the basis of natural group lacy ducks; and the meat duck new breed with consistent appearance and stable heritability are bred by the traditional breeding method and the modern molecular breeding method.

Description

technical field [0001] The invention relates to a poultry breeding method, in particular to a method for producing a new strain of lace duck with two-spotted flowers. Background technique [0002] Lace duck, also known as four-point flower duck, is a hybrid of Cherry Valley breed and Shelduck duck breed, Baiyu Tianfu meat duck male duck and Sichuan native Shelduck duck, and some people think it is a kind of Guangxi Shelduck duck , belongs to the meat and egg type duck species. When hatching, the feathers are mainly yellow, and there are white, brown and black feathers on the head, neck, chest and back or tail. After moulting in adulthood, part of the coat color is completely white, and there are brown or black feathers on the upper four sides, which are very similar to lace in traditional clothing, hence the name. The feather color of the current lace duck is not uniform, and the distribution of black feather bands is chaotic and disorderly. When consumers and farmers purc...

Problems solved by technology

Lace duck is very suitable for the local traditional eating method in Sichuan. It has a complete color and fragrance. However, this variety has not been systematically selected, and its appearance is not uniform. It is often misunderstood by consumers when purchasing. It also has slow growth, low productivity, and high feeding costs. , which has a certain restrictive effect on both the breeder and the consumer
