Animal and plant breeding value prediction method and device

Abstract

The invention discloses an animal and plant breeding value prediction method and device, and belongs to the field of breeding value prediction. The method comprises the following steps: after a genome is obtained, carrying out single nucleotide polymorphism labeling on the genome; then obtaining a marker of each chromosome, and constructing an intermediate matrix for the marker of each chromosome; combining all the intermediate matrixes to obtain a genetic matrix of the genome; calculating a first breeding value according to the genetic matrix; constructing a weight intermediate matrix for the marker of each chromosome according to the first breeding value; obtaining a weighted genetic matrix of the genome according to the weight intermediate matrix; and finally, calculating the weighted genetic matrix to obtain a final breeding value. According to the prediction method provided by the scheme of the invention, after the first breeding value is calculated, the marker of each chromosome is weighted according to the first breeding value, assuming that all markers have effects is not needed, high-density marker information is effectively utilized, the accuracy of the final breeding value is improved, the calculation process is simple, and the prediction time and calculation cost are reduced.

Description

Technical field[0001]The present invention relates to a proposed value prediction technique, in particular, to a method and apparatus for a graft breeding value prediction method and apparatus.Background technique[0002]The breeding value is the value of the species of the country. In the number of genetics, the genotype effect value of the determined amount of traits is defined as the breeding value (BV), and the estimate of the sports species is called an estimated breeding value (EBV). The breeding value of the predicted plants is of great significance for animal plant breeding, but the traditional prediction method can be substantially divided into two types of direct methods, indirect method, direct law such as GBLUP, SSGBLUP, etc., indirect method such as Bayesa, Bayesb, Bayesc, etc.[0003]The standard GBLUP method assumes that all tags have an effect, and the tag is filtered, and all molecular marks are used to construct a protriction, which in turn is solved to the hybrid mode...
