Lean type muscovy duck strain breeding method based on molecular marker

Abstract

The invention discloses a molecular marker-based lean type muscovy duck strain breeding method, which comprises the following steps: S1, conventional breeding of a high-quality muscovy duck new strain: establishing conventional breeding standards of a high-quality muscovy duck paternal line and a maternal line, including paternal line growth speed, meat production rate, maternal line reproductive performance and the like; and continuously breeding for two generations according to a conventional breeding standard. According to the Muscovy duck breeding method, conventional breeding is combined with a modern molecular marker assisted breeding technology in Muscovy duck breeding for the first time through Muscovy duck improved variety breeding and application projects, a male parent of the strain focuses on selection of the growth speed, the sebum rate and the meat yield, a female parent of the strain focuses on selection of breeding traits, the automation and competitiveness of the industry are improved, and the breeding cost is reduced. Then, gene molecular markers such as MSTN and PRL are applied to breeding of the new high-quality lean type muscovy duck strain, the problems that the strain breeding progress is slow, and recessive characters cannot be removed through conventional selection are solved, and an advanced breeding technology can be provided for breeding enterprises.

Description

technical field [0001] The invention relates to the technical field of selection and breeding of lean-meat Muscovy duck strains, in particular to a method for selection and breeding of lean-meat type Muscovy duck strains based on molecular markers. Background technique [0002] The domestic demand for high-quality Muscovy duck is growing rapidly. Traditional Muscovy duck varieties can no longer meet the production requirements and have become a bottleneck restricting the development of the Muscovy duck industry. Therefore, the current demand for new Muscovy duck varieties (matching lines) is imminent. Duck meat is an important source of high-quality protein for Chinese consumers, and it is rich in unsaturated fatty acids that are beneficial to human health. Widely concerned, the duck breeding and application project uses biological breeding technology to cultivate the improved Muscovy duck. Compared with the Muscovy duck before breeding, the screened new line of high-quality...

Problems solved by technology

[0003] (1) At present, the production of Muscovy Duck in my country is developing rapidly, but there is a lack of high-quality independent varieties of Muscovy Duck, so the independence and competitiveness of the entire industry are relatively low; Therefore, the production performance of Muscovy Duck is unstable and the reproductive rate needs to be improved; (3) The technical system of Muscovy Duck breeding in my country needs to be further improved
