CN102550480A - Hybrid synthetic line breeding method of high-quality high-yield geese with special marks - Google Patents

Abstract

The invention relates to a hybrid synthetic line breeding method of high-quality high-yield geese with special marks, which includes the steps: firstly, separating male geese with three flowers and female geese with three flowers for breeding, and reestablishing groups; secondly, performing expanded group breeding by combining group breeding with family breeding and combining family breeding with individual breeding; thirdly, performing enclosed feeding based on the family breeding and the group breeding; fourthly, measuring combining ability of three specialized strains in positive-reverse cross multi-group; fifthly, sorting out the best group; sixthly, expanding the group of parents; and seventhly, performing synthetic line breed preparation and producing commercial geese. Three-flower geese with special marks bred by the method are produced as commercial geese, meat features of the variety and adaptability to local ecological conditions are retained well, the best group is sorted out by using the strain growing fast in the early stage as female parents and using hybrids of the high-quality strain high in egg laying rate and high in fodder utilization rate as male parents, and accordingly growth speed is fast, the egg laying rate is high, the fodder utilization rate is high, and production cost is low.

Description

A kind of good quality and high output goose corss combination with special marking is a breeding method

Technical field

The present invention relates to a kind of biological poultry genetic breeding field, relating in particular to a kind of good quality and high output goose corss combination with special marking is breeding method.

Background technology

Though China's goose kind aboundresources, the overwhelming majority is that the direct utilization or the simple hybridization of goose kind resource utilizes, even the external good goose kind of introducing also is that simple hybridization utilizes, does not select through the cultivation of system.Can not improve the productivity of goose like this, also damage the protection of China's goose kind resource simultaneously.Though domestic some unit has at present cultivated combination of goose corss combination and supporting system, because of its limited amount, does not also have obvious characteristic simultaneously.So not only can not satisfy the demand of breed, and utilized by the people easily, mix the spurious with the genuine, adulterate, lead the culturist into a trap, therefore need to cultivate the supporting system of goose good-quality high-yield hybrid with special marking.

Summary of the invention

The object of the present invention is to provide a kind of good quality and high output goose corss combination with special marking is breeding method.

Technical scheme of the present invention is: this breeding method is undertaken by following step:

1) in cultivating Yangzhou goose new varieties process, the isolated a small amount of 3-4% of breeding population at the gooseneck boom top, tail feathers root, oxter, both sides have the public female goose that the little piebald point of black promptly is referred to as three flowers and separately raise reconstruction colony;

2) with the colony of reorganization, set up family, adopt jumpbogroup seed selection and family selective breeding in 1 public 6 female ratio; The method that family selective breeding combines with individual seed selection; Expand mass selection and educate raising, stablize its inheritance, have the material of the good quality and high output goose corss combination system of special marking as cultivation;

3) on the basis of family selective breeding and jumpbogroup seed selection, formation lay heavily, three specialized strains that early growth speed is fast and efficiency of feed utilization is high, each specialized strain man coefficient reaches 40, carries out enclosed grazing, continues to improve productivity and genetic stability;

4) above-mentioned lay heavily, early growth speed is fast and efficiency of feed utilization is high three specialized strains are carried out positive and negative intersection and make up combining ability test more;

5) be male parent with the fast strain of early growth, the filial generation of lay heavily and the high strain of efficiency of feed utilization is maternal, filters out best of breed;

6) parent expands the crowd, continues seed selection and improves;

7) carrying out supporting is the production of hybrid seeds, produces the commodity goose.

Three colored geese with special marking that the present invention cultivated are cooked the commodity goose and produce, and have not only well kept the meat characteristic of this kind and the adaptability of local ecological condition, and the present invention is a male parent with the fast strain of early growth; The filial generation of lay heavily and the high strain of efficiency of feed utilization is maternal; Filter out best of breed, fast growth, lay heavily; Efficiency of feed utilization is high, and production cost is low.

Embodiment

A kind of good quality and high output goose corss combination with special marking is a breeding method, and this breeding method is undertaken by following step:

2) with the colony of reorganization, set up family, adopt jumpbogroup seed selection and family selective breeding in 1 public 6 female ratio; The method that family selective breeding combines with individual seed selection; Expand mass selection and educate raising, stablize its inheritance, have the material of the good quality and high output goose corss combination system of special marking as cultivation;

3) on the basis of family selective breeding and jumpbogroup seed selection, formation lay heavily, three specialized strains that early growth speed is fast and efficiency of feed utilization is high, each specialized strain man coefficient reaches 40, carries out enclosed grazing, continues to improve productivity and genetic stability;

4) above-mentioned lay heavily, early growth speed is fast and efficiency of feed utilization is high three specialized strains are carried out positive and negative intersection and make up combining ability test more;

5) be male parent with the fast strain of early growth, the filial generation of lay heavily and the high strain of efficiency of feed utilization is maternal, filters out best of breed;

6) parent expands the crowd, continues seed selection and improves;

7) carrying out supporting is the production of hybrid seeds, produces the commodity goose.
