Problems solved by technology

[0003] At the same time, in the prior art, because the sex characteristics of the chicks are quite inconspicuous, the sex identification of the chicks is mostly carried out through human eye observation. During this process, certain damages will be caused to the chicks, which is not conducive to the growth of the chicks. A more convenient and effective gender identification method

Embodiment 1

[0048] The dwarf yellow chicken was used as the male parent, and the Beijing oil chicken was used as the female parent to obtain the F1 generation. In the F1 generation, individuals with the characteristics of hairy feet, slow feathers and short feet were selected for cross-crossing, and the slow-feather cocks were genetically Type determination and selection to breed slow-feather dwarf chickens with stable traits.

[0049] With the slow-feathered dwarf chickens obtained above as the female parent, and the Suqin yellow chicken as the male parent, the high-yielding chickens were obtained by crossing. Distinguish its male and female, the slow feather is a male chicken, and the fast feather is a female chicken.

Embodiment 2

[0051]Using Xinxing Yellow Chicken No. 2 mating line as the male parent and Jinhu Wufeng chicken as the female parent, the F1 generation was obtained by crossing. In the F1 generation, individuals with the traits of hairy feet, slow feathers and short feet were selected for cross-crossing, and The slow-feather roosters were genotyped and selected, and the slow-feather dwarf chickens with stable traits were bred.

[0052] Using the slow-feathered dwarf chickens obtained above as the female parent and the Jinling yellow chicken as the male parent, the high-yielding chickens were obtained by crossbreeding. Among the high-yielding chickens obtained from the commercial generation, they can be distinguished according to the characteristics of their fast and slow feathers. Its male and female, the slow feather is the male chicken, and the fast feather is the female chicken.

Embodiment 3

[0054] The Lingnan yellow chicken was used as the male parent and the Minqing Maojiao chicken was used as the female parent to obtain the F1 generation. In the F1 generation, individuals with the traits of hairy feet, slow feathers and short feet were selected for cross-crossing. Genotype determination and selection were carried out to breed slow-feathered dwarf chickens with stable traits.

[0055] With the slow-feathered dwarf chickens obtained above as the female parent and the Kangdal yellow chicken as the male parent, high-yielding chickens were obtained by crossbreeding. Among the obtained commercial generation high-yielding chickens, according to the traits of their fast and slow feathers, they can be Distinguish its male and female, the slow feather is a male chicken, and the fast feather is a female chicken.

Abstract

The invention provides a high-yield ranunculus japonicas seed production method. According to high-yield ranunculus japonicas, slow-feathering dwarf chicken are adopted as a male parent, local ranunculus japonicas is adopted as a female parent, hybridization is performed to obtain a generation F1, seed selection, mating testing and crossing character fixation of the generation F1 are performed to form slow-feathering, small and short and dry foot synthetic lines to be hybridized with the fast-feathering dorking male parent to obtain the high-yield ranunculus japonicas, and according to the obtained high-yield ranunculus japonicas, hens are fast-feathering lines, and roosters are slow-feathering lines. The high-yield ranunculus japonicas cultured through the method has the advantages of the local ranunculus japonicas, is good in meat quality, and meanwhile has the advantages of being high in yield, high in breeding bird laying rate and rapid in dorking growth vigor.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a seed production method for high-yield hairy chickens. Background technique [0002] Local chicken breeds have the characteristics of unique appearance and beautiful meat quality, but their growth rate is slow and their feed conversion rate is low. Hairy feet (shin feathers) are the unique traits of local breed chickens. The market price of live chickens or slaughtered chickens with hairy feet can be more than 10% higher than that of similar products, and the sales volume will also increase. At the same time, the production performance of local varieties is low, the reproductive performance is poor, the growth is slow, and the production cost is high. Breeding a strain with hairy feet and high yield is of great significance for improving the economic benefits of breeding. [0003] At the same time, in the prior art, because the sex characteristics of the chicks are qu...
