Families for seed reserving and performance testing are separated, related heritability coefficients rA are calculated according to results of performance testing, and selection of different seed selection methods is performed according to calculation results. By the method, seed reserving rate is lowered on the premise of not increasing cost, and selection response is improved greatly, so that the purpose of accelerating breeding progress is achieved. Therefore, the method has broad market and scientific research prospects.
Description
Technical field
The present invention relates to a kind of aquatic livestock breeding method, particularly a kind of performance measurement and the aquatic livestock breeding method of reserving seed for planting and being separated.
Background technology
In current aquatic livestock breeding plan, for the family content of performance measurement or population size generally in tens to 100 individualities, the selection of this individual amount can guarantee to estimate under prerequisite, to save cultivation and cost of determination accurately at breeding parameters, but because performance measurement colony is seed selection colony, therefore when seed selection, the rate of reserving seed for planting is difficult to lower than 1%, and this makes the feature of aquatic livestock prolificacy can not get effectively utilizing and performance.General aquatic livestock, single parent can produce the offspring of a myriad of, if can choose seeds from whole offsprings, the rate of reserving seed for planting can be reduced to 1 ‰, even ten thousand/more than.According to Quantitative Genetics principle, at parent's breeding value variance and heritability constant in the situation that, the rate of reserving seed for planting is reduced to 1 ‰ from 1%, can make to select reaction to improve 26.3%, thereby accelerate breeding process.Therefore need now a kind of new aquatic livestock breeding method that can address the above problem.
Summary of the invention
The present invention is in order to solve the existing above-mentioned deficiency of prior art, proposes one and both can carry out performance measurement, can reduce again the aquatic livestock breeding method of the rate of reserving seed for planting.
Technical solution of the present invention is: a kind of performance measurement and the aquatic livestock breeding method of reserving seed for planting and being separated, is characterized in that: described method is carried out according to following steps:
A, the aquatic livestock of seed selection is carried out to the structure of multiple breeding familys, each family at least comprises 1100 individualities,
B, when the aquatic livestock of seed selection reaches required seed size, according to existing cultivating condition and performance test condition, from each family, 30-100 of random selection is individual as performance measurement colony respectively, and according to family, carry out mark respectively, all individualities of selecting are raised together with, or according to family be unit divide support, point support time must guarantee that the breeding environment of each family is consistent
After c, described step b finish, the individuality that in the remaining individuality of each family, upper choosing meets breeding objective most from step a is as reserving seed for planting colony, and selection ratio is lower than 2 ‰, and according to family, carry out mark respectively, all individualities of selecting are raised together with, or according to family be unit divide support, point support time must guarantee that the breeding environment of each family is consistent
After d, described step b finish, performance measurement colony is carried out to performance measurement for the first time, and before producing family of future generation, performance measurement colony carries out performance measurement for the second time, according to measurement result and breeding plan, from performance measurement colony, select n family that approaches breeding objective most, be labeled as GM
i(i=1,2 ... n), from the colony of reserving seed for planting, select n the family corresponding with performance measurement colony, be labeled as GS
i(i=1,2 ... n),
E, according to twice performance measurement result in steps d, the genetic correlation coefficient r when calculating objective trait and separating in performance measurement colony and during seed selection

If f is r
a>=0, carry out step g, if r
a<0, carries out step h,
G, from the GS of the colony of reserving seed for planting
iin family, choose seeds, and seed selection rate is lower than 50%, to guarantee always to reserve seed for planting rate lower than 1 ‰ in family,
H, from the GM of performance measurement colony
iin family, choose seeds, and seed selection rate is identical with conventional method, in its family, reserves seed for planting rate higher than 1%.
Compared with the existing technology, tool has the following advantages in the present invention:
Aquatic livestock breeding method disclosed in this invention, for the lower problem of the rate of reserving seed for planting in traditional breeding way, by separation the family of reserving seed for planting with performance measurement, and carries out genetic correlation coefficient r according to the result of performance measurement
acalculating, according to result of calculation, carry out the selection of different seed choosing methods, its appearance has reduced the rate of reserving seed for planting under the prerequisite not raising the cost, and allows and selects reaction greatly to promote, thereby reach, accelerates the object of breeding process.Therefore this method possesses market and scientific research prospect widely.
Embodiment
The specific embodiment of the present invention will be described below.
Performance measurement and the aquatic livestock breeding method of reserving seed for planting and being separated, according to following steps, carry out:

i(i=1,2 ... n), the final GM from performance measurement colony
iin family, choose seeds, in its family of this mode, the rate of reserving seed for planting is not less than 1%.
Embodiment:
Take sea urchin as example, operation as follows:
Build 10 breeding familys, and each family content is no less than 2000 individualities;
When 6 monthly age, from each breeding family, 50 individualities of random selection, are divided into 10 groups of performance measurement colonies take family as unit, and divide and support, and guarantee that the breeding environments such as each family water temperature, bait are consistent;
From each breeding family residue offspring, select the individuality of 4 individual weight maximums as the colony of reserving seed for planting, selection ratio is about or lower than 2 ‰.The individuality of reserving seed for planting in each family is divided into 10 groups of colonies of reserving seed for planting take family as unit, and divides and support, and guarantee that the breeding environments such as each family water temperature, bait are consistent;
When 6 monthly ages and 19 monthly age, respectively performance measurement colony is carried out to body weight determination, according to measurement result, calculate the growth rate of each colony (family) body weight, select colony's (family) that 5 individual weight growths are the fastest and be designated as GM1, GM2, GM3, GM4, GM5; The family of reserving seed for planting of correspondence is GS1, GS2, GS3, GS4, GS5 with it,
The data at 6 monthly ages and 19 monthly ages in step in utilization, when calculating body weight and separating in performance measurement colony and the genetic correlation coefficient r in while seed selection
a=0.65;
Result of calculation r
a>=0,
From GS1 ~ GS5 family of the colony of reserving seed for planting, choose seeds, every family selects 2 parents for the production of breeding population of future generation, and in this process family, always the rate of reserving seed for planting is about or lower than 1 ‰, and always the rate of reserving seed for planting is about or lower than 0.5 ‰.
And if according to conventional method, from GM1 ~ GM5 family of the A of colony, choose seeds, the rate of always reserving seed for planting is minimum is 1%, therefore this method estimate select reaction more conventional system of selection promote more than 33.4%.
