Abstract:
|
Genomic selection (GS) has become an important tool in breeding. Accordingly, statistical approaches for genomic assisted prediction have also evolved. Meuwissen et al. (2001) proposed parametric methods for GS. Nonparametric methods for GS, which require fewer assumptions than parametric methods, can handle the multiplicity of potential interactions across the genome. In this presentation, we implement some of the parametric and nonparametric methods for GS using simulated data containing phenotypic and marker information on F2 and BC populations. We consider marker data with and without interactions, and we compare the performance of the methods for predicting the genetic value for individuals in the plant breeding populations. The performance of the different methods is illustrated by comparing the accuracy of prediction. We show the advantage of using nonparametric models when interaction presents.
