Method for performing whole genome selective breeding by selecting extreme character individual

The invention discloses a method for performing whole genome selective breeding by selecting extreme character individuals. The method comprises the following steps: as for a certain amount of characters, selecting part of individuals of which the character expression is extreme, wherein the individuals of highest character expression and the individuals of lowest character expression respectively account for one half; constructing an estimation group, and performing character measurement on the estimation group; performing genome sequencing and whole genome SNP label excavation on an extreme character reference group and the estimation group; calculating the breeding effect value of each SNP label according to phenotypic values and gene type information of the extreme individuals, performing whole-genome typing on the estimation group so as to obtain the breeding values of the individuals in the estimation group, and performing final seed selection on the estimation group. According to the method, the influe
