Problems solved by technology

But for a long time, these five kinds of Oujiang color carps have been mixed with each other, and their respective characters are not outstanding, and some of them have relatively serious trait degeneration. They need to be purified and selected to purify their genotypes and highlight their respective excellent phenotype economic traits

specific Embodiment approach

[0023] The present invention takes body weight, body shape and color as the breeding goals, and establishes five specialized strains of Oujiang colored carp, namely "Quanhong", "Dahua", "Twist", "Penyu" and "Fenhua", and locks each strain The group selection has formed the "specialized" characteristics of each strain with specific body color, differentiated body shape, and different growth speed. The mating of different strains can produce significant hybrid vigor, and five specialized strains have reached the maturity level. For this purpose, matching line breeding can be carried out. The specific implementation is as follows:

[0024] 1. Establishment of specialized strains

[0025] The source of the strain: Zhejiang Longquan Provincial Oujiang Colored Carp Breeding Farm.

[0026] Strain establishment: Body color is used as the main classification basis for strain establishment, and strains are established according to five body colors of "quanhong", "big flower", "twist f...

Abstract

The invention discloses a breeding method for five specialized lines of Oujiang color common carp, and the method comprises the following steps: (1) establishing the specialized lines of the Oujiang color common carp according to main classification basis for establishing the lines by body weight and body color; (2) adopting the closed population continuing selection and breeding method for performing closed population continuing selection and breeding on the established lines, purifying genotypes of the lines, and improving the breeding characters of the lines; (3) performing selection in the lines, and breeding more than 4 generations; and (4) evaluating matching effects. The five specialized lines bred by the method are full red, big flower, twisted, pink jade and pink flower, and have excellent phenotypic economic characters, such as fast growth speed, pure external body color and the like, thereby providing specialized parent materials for popularization of synthetic line fries with significant hybrid vigor.

Description

technical field [0001] The invention relates to a method for breeding and purifying five specialized strains of Oujiang colored carp (Cyprinus carpio var. Background technique [0002] Complete set line breeding is a breeding method that uses "specialized" strains with certain (some) economic traits for crossing to produce a complete set with significant "heterosis". As an advanced breeding method, mating line breeding is widely used in crops, poultry and livestock breeding, and has achieved remarkable results. However, in aquatic organisms, mating line breeding is still in the initial stage of exploration. [0003] The material basis for carrying out mating line breeding is specialized strains with relative character differences and a certain genetic purity, and the cultivation of specialized strains (that is, the construction, selection and purification of specialized strains) is the premise of mating line breeding. Due to factors such as geographical isolation, natural ...
