基因组选择在反刍动物中的应用与研究进展OA

Genome selection is to estimate the effect values of all genetic markers in the target population at the whole genome level to accurately predict the unknown phenotypes of candidate populations,which can realize the early selec-tion of breeding.This technique makes up for the shortcomings of traditional breeding,has the advantages of shorte-ning generation interval and reducing breeding cost,and is especially useful for the evaluation of low heritability or eco-nomically important traits that are difficult to measure.Due to the improvement of prediction accuracy and the decrease of genotyping price,genome selection has been applied rapidly.Therefore,this paper reviewed genome selection,the research on ruminants with important economic value,and the opportunities and challenges they face,so as to provide theoretical reference for genome selection in ruminants.
