Genomic selection has developed, since the mid 1990s, from a hypothetical concept to a practical way of applying genetic marker data in breeding. As the name suggests, the objective of genomic selection is to provide breeders with a method of making selections in breeding programs. This stands in contrast to statistical approaches, such as association genetics, that were initially developed to identify specific genes, or even specific DNA sequence variants as the causative agents underlying phenotypic variation.
This module provides an historic perspective of genomic selection and an overview of different approaches to the computational problems of estimating breeding value from marker genotypes. Successful application of genomic selection to dairy cattle breeding is presented. The module also includes discussion of strategies that may be useful in applying genomic selection to forest tree breeding.
