Modeling Multi-Stage Selection

Authors: Jack C. M. Dekkers (Iowa State University) , Hailin Su (Iowa State University)

Abstract

In this study, we introduced and applied Truncated Multivariate Normal distributions, on top of standard quantitative genetics theory and selection index theory, to reliably model the multi-stage selection breeding programs. Compared to the previously available SelAction software (Rutten et al. 2002), this new approach properly models the change in genetic parameters in multi-stage selection, and is capable of evaluating selective breeding programs with more than three selection stages.
