About the Webinar

This webinar focuses on genomic selection in R using the rrBLUP package. Through this webinar you will learn to generate a training population, impute missing markers, estimate marker effects and determine the correlation accuracy.

Learning Objectives

  1. Download the package and load in the example files
  2. Define training and validation populations
  3. Impute missing markers using the A.mat command
  4. Run mixed.solve and determine accuracy of predictions

Software Downloads
