Development of genomic breeding value estimation for dual purpose Fleckvieh
Abstract
Use of molecular markers for improvement of genetic evaluations is a major topic in animal breeding. High throughput genotyping technologies enable the genotyping of 50,000 single nucleotide polymorphisms (SNP). Application of dense marker information in combination with genomic selection has been suggested. Genomic selection uses the information of all markers simultaneously for prediction of breeding values. The objective of the project is to develop a formula for the estimation of genomic breeding values. 1,000 dual purpose Fleckvieh bulls will be genotyped using a 50,000 SNP chip. For the formula development the following statistical methods will be compared: principal component regression, partial least squares, and multiple regressions using least angle regression for variable selection. Routinely estimated and genomic breeding values will be combined making proper use of all information.
