Example Embodiment

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

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

[0045] Such as figure 1 As shown, a biological information-based breeding system uses a whole genome selection method to first obtain the genome data of the reference population and the individual candidate population. For genotype data, SNP genetic markers are currently commonly used to obtain, an...

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...
