Abstract
The invention relates to a method for breeding a white Rex rabbit new variety. The white Rex rabbit new variety with blue-eye characteristic is bred by using a white Rex rabbit as a male parent and using a chinchilla rabbit as a female parent and by methods of hybridization, backcross and the like. The breeding method is short in time and high in speed. The Rex rabbit new variety bred by the method has the advantages of maintenance of body form of the chinchilla rabbit, high growth speed at the early stage, high feed utilization ratio, high lactation capacity, high breeding rate, coarse feeding resistance, high disease resistance and the like. The white Rex rabbit new variety is distinguished from other white Rex rabbit varieties easily because the white Rex rabbit new variety has unique appearance characteristics of white clothing hairs, flat and upright fine hairs, blue eyeballs, penetrating eyes, big and upright ears and white pelt which is a first-class fur clothing raw material in the Rex rabbit industry.
Description
Technical field
The present invention relates to the breeding method of a kind of otter rabbit, a kind of specifically white is made every effort to overcome the breeding method of these rabbit new varieties.
Background technology
The otter rabbit that China raises mainly is to introduce from countries such as the U.S., France and Britain, otter rabbit strains such as U.S. system, the genealogy of law have been formed, hair color about the otter rabbit has a lot of types, 14 kinds of admitting of U.S. otter rabbit association, what Britain was admitted has 28 kinds, mainly by castor look, chocolate, white, black, rufous, faint yellow, Himalaya look, pewter, livid purple blueness etc., these colour patterns become the important symbol of different colour systems of commercial identification and quality to the colour pattern that China introduces.China introduces the otter rabbit since the eighties in last century from the U.S., white otter rabbit is promoted the most extensive in China.At present China otter rabbit to culture the subject matter that exists be (1) " heavily introduce a fine variety, light seed selection "; (2) " heavily fall kind, the light cultivation ", (3) " hybridization is disorderly joined " phenomenon serious.More than several situations cause finally that inbreeding depression is serious, the rabbit quality descends and the population market confusion, China otter rabbit does not have oneself population market for many years, is subjected to external pining down more, the otter rabbit breeds of therefore cultivating China oneself uniqueness is very necessary.As everyone knows, white otter rabbit and common white rabbit, because the effect of albefaction gene, eyes all are pink.Draw from external white otter rabbit, after China,, be difficult to distinguish the difficulty that causes kind identification and identify from profile owing to be subjected to the influence of factors such as region, feeding and management condition and seed selection for a long time.The genetic development of wink of the present invention, hair color and wool type locus by in a planned way hybridization, sib mating and method such as backcross, has proposed the breeding method of blue white of the eye look otter rabbit.Cultivate blue white of the eye look otter rabbit new varieties and not only enriched the existing otter rabbit breeds gene pool of China,, promote that the development of otter rabbit aquaculture is significant improving the population structure of China otter rabbit.
Summary of the invention
The present invention is directed to the deficiency of the problems referred to above, the breeding method that provides a kind of white to make every effort to overcome these rabbit new varieties, thus cultivate otter rabbit breeds with Chinese characteristics.
The present invention addresses the above problem the technical scheme that is adopted to be: white is made every effort to overcome the breeding method of these rabbit new varieties:
Obtain the breeding method that white is made every effort to overcome these rabbit new varieties by half-sib mating or sib mating:
One, half-sib mating:
Step 1, select for use 5-10 of white otter rabbits as male parent, 20-40 of livid purple blue meat rabbits hybridize as female parent, obtain F1 and have 1/16-1/8 white for hybrid population and make every effort to overcome this rabbit;
Step 2, select to have 5-10 of the buck that blue eye and white are made every effort to overcome this wool type feature in for hybrid population at F1,20-40 of female rabbits carry out half-sib mating or sib mating, obtain F2 and have 1/8-1/4 white for hybrid population and make every effort to overcome this rabbit;
Step 3, select to have 5-10 of the male and females that blue eye and white are made every effort to overcome this wool type feature in for hybrid population at F2,20-40 of female rabbits, carrying out the generation traversed by fixes, in the offspring who obtains, eliminate other hair color and common wool type individuality in per generation, after 5-6 generations, make blue eye and make every effort to overcome this wool type genetic stability, make every effort to overcome this wool type otter rabbit new varieties by expanding group, seed selection, cultivate the white that becomes to have blue eye feature.
Two, the mating of backcrossing
Step 4, select 5-10 of white otter rabbits as male parent, 20-40 of livid purple blue meat rabbits hybridize as female parent, obtain F1 and have 1/16-1/8 white for hybrid population and make every effort to overcome this rabbit;
Step 5, select F1 to make every effort to overcome 5-10 of the buck of this wool type feature and backcross, obtain first backcross generation BF1 hybrid population and have 1/8-1/4 white and make every effort to overcome this rabbit with 20-40 of the livid purple blue meat rabbits of female parent for having blue eye and white in the hybrid population;
Step 6, select to have in the first backcross generation BF1 hybrid population 5-10 of the buck that blue eye and white are made every effort to overcome this wool type feature, 20-40 of female rabbits, carrying out the generation traversed by fixes, in the offspring who obtains, eliminate other hair color and common wool type individuality in per generation, after 5-6 generations, make blue eye and make every effort to overcome this wool type genetic stability, make every effort to overcome the otter rabbit new varieties of this wool type by expanding group, seed selection, can cultivate the white that becomes to have blue eye feature.
The first generation that described BF1 produces on behalf of the back of backcrossing.
Beneficial effect
The white that the inventive method is cultivated is made every effort to overcome this rabbit new varieties, has kept the build of livid purple blue meat rabbit, and it is fast to have early growth speed, the efficiency of feed utilization height, lactation power is strong, crude feed tolerance, advantages such as premunition is strong, its unique macroscopic features very easily is different from other otter rabbit breeds.Whole body is by hair white, and two have god, two eyeball navy blues, and fine hair is smooth upright, and rabbit hair difficult drop-off is the better-than-average FUR GARMENT raw material of otter rabbit industry.
