Method for producing seeds of spotted goose seedlings

Abstract

The invention discloses a method for producing seeds of spotted goose seedlings. The method comprises the following steps: (1) performing self-group propagation on breeding geese with spotted feathercharacteristics; (2) establishing a white feather group for white feather mutation male and female geese appearing in self-group propagation offspring, and performing family breeding combined with individual breeding to breed a white feather high-yield line; (3) performing reciprocal cross of spotted feathers and the white feather mutation male and female geese, and screening out spotted feather homozygous individuals according to the separation of the feather color of the offspring; (4) establishing a spotted feather group for the spotted feather homozygous male and female geese, and performing family breeding combined with individual breeding to breed a spotted feather fast-growing line; and (5) performing cross utilization on the bred spotted feather fast-growing line male geese and thewhite feather high-yield line female geese to produce the spotted feather goose seedlings. Compared with the prior art, the method disclosed by the invention can realize the 100% of the spotted rateof the offspring, fully utilizes the advantage of high reproductive performance of the maternal line, significantly reduces the production cost of the goose seedlings, can meet the market demand for the spotted goose seedlings, and has good potential large-scale application prospects.

Description

technical field [0001] The invention relates to a seed production method of piebald goose seedlings, and belongs to the technical field of seed production of piebald goose seedlings. Background technique [0002] In recent years, with the acceleration of the industrialization of meat geese, the market demand for piebald (gray spots on both sides of the head and back) geese is increasing, because this type of geese not only grows fast, but also has an average growth rate of 70 days. The weight can reach about 4000g. At the same time, goose seedlings are 2-3 yuan higher than ordinary goose seedlings. They are very popular among commercial goose farmers and goose breeding enterprises. However, in the current breeding process of pure-line piebald geese, not only the offspring feather color separation often occurs, but farmers often think that the breed is impure and deliberately lower the price of goose seedlings. left and right, causing the production cost of goose seedlings t...

However, in the current breeding process of pure-line piebald geese, not only the offspring's feather color separation often occurs, but farmers often think that the breed is impure and deliberately lower the price of goose seedlings. left and right, causing the production cost of goose seedlings to remain high, seriously affecting the supply of high-quality goose seedlings in the market
