Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0044] The specific implementation manner of the present invention will be further described in detail below in conjunction with the schematic diagrams.

[0045] Such as figure 1 As shown, a biological information-based selective breeding system adopts the genome-wide selection method, and first obtains the genome data of reference populations and candidate populations. SNP genetic markers are generally used to obtain genotype data, and commercial SNP chips are av...

Abstract

The invention relates to the field of the biological technology, and specifically discloses a seed selection and breeding system based on biological information, and an algorithm of the seed selection and breeding system. The system integrates the linkage imbalance and linkage analysis information among individuals in a whole genome, makes more comprehensive and complete use of the genome data information and family tree information of the individuals, can give better play to the advantages of genome selection in the field of agricultural breeding, predicts whole genome breeding values of the individuals of a candidate group, calculates the correlation coefficient of the whole genome breeding values and the real breeding values of the individuals in simulation data as the accuracy index of the prediction of the whole genome breeding values and can achieve the accurate prediction so as to achieve the high-efficiency specific breeding. In addition, the method provided by the invention can facilitate the detection and determination of functional genes correlated with some specificity, and facilitates the implementation of specific breeding.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a biological information-based breeding system and an algorithm thereof. Background technique [0002] In the industrial chain of agricultural organisms (crops, livestock and aquatic organisms), improved seed selection plays a vital role. Traditional breeding methods are mostly based on genetic statistical principles combined with actual production, use the trait records of candidate individuals and (or) relatives to estimate their breeding value, and use the breeding value as an indicator to achieve variety breeding through multi-generation artificial breeding and trait improvement. However, this method often has the disadvantages of long breeding cycle and large consumption of manpower and material resources. For example, it took more than 30 years for the "Big York" pig in France to be successfully bred. In the field of dairy cattle breeding, it takes 5-6 years to verify a cand...
