Problems solved by technology

However, for a long time, the Oujiang colored carp has been "sleeping" in the Oujiang River Basin, and is in the self-propagation and self-cultivation of farmers. It lacks purposeful selection and development, resulting in mixed body colors, unstable offspring genetics, single color and poor brightness.

specific Embodiment approach

[0029] The present invention takes the color and black markings as the breeding targets, and establishes the foundation colonies for the selection and breeding of Oujiang color carp with five body colors of "full red", "big flower", "twist", "pink jade" and "pink flower". Combination of breeding, subpopulation breeding and group breeding, each generation of offspring with the same body color, bright colors and pleasing stripes will be bred in a closed group until the sixth generation (F 6 ), and their body color homozygosity are: "Quanhong" 100%, "Dahua" 92.69%, "Twist" 91.55%, "Fenyu" 100%, "Fenhua" 99.80%. It has become a selected breed with stable phenotype, high genetic homozygosity, richer color and more pleasing markings, which can be used for ornamental breeding. The specific implementation is as follows:

Abstract

The invention discloses a method for breeding ornamental type Cyprinus carpio var. color. The method comprises the following steps of: (1) establishing a foundation group, namely establishing an ornamental type Cyprinus carpio var. color breeding foundation group by taking colors and black stripes as breeding targets; and (2) breeding by a family breeding, subformation breeding and group breedingcombined method, wherein the former two generations adopt a family breeding and subformation breeding combined method; the later four generations adopt a group breeding method; and the breeding groups in each generation are selected for four times. The ornamental type Cyprinus carpio var. color, which has five body colors of 'all red', 'large design and color', 'linen design and color', 'pinky jade green' or 'pinky design' and is bred by the method, has stable body color homogeneity, stable phenotypic character and high homozygosity and can serve as ornamental type fish for mass production.

Description

technical field [0001] The invention relates to a method for breeding and purifying five kinds of ornamental Oujiang colored carp (Cyprinus carpio var. color) ("full red", "big flower", "twist", "pink jade" and "pink flower"). Background technique [0002] Ornamental fish has been loved by the general public for a long time, and there are more than 1,100 species of ornamental fish in the world at present. Among freshwater ornamental fish, my country's goldfish and Japanese koi are the most famous. With the improvement of people's living standards, the ornamental fish breeding industry has more and more significant market prospects and industrial potential. The annual trade volume of ornamental fish in my country is more than 15 billion yuan. Ornamental fishery has become a new growth point of my country's and even the world's aquatic industry, and has great development prospects. [0003] Oujiang colored carp (Cyprinus carpio var.color) is a local carp species widely culti...
