Tentative workshop outline:
The workshop will mostly follow the textbook Isik-Holland-Maltecca (2017) Genetic data Analysis for Plant and Animal Breeding with hands-on examples.

The tentative outline is as follows:

  • Theory of linear mixed models
  • ASReml software basics and options
  • Breeding values and genetic values
  • Multi environmental trials using factor analytic models
  • Spatial analysis of field test data
  • Explanatory marker data analysis
  • Imputing missing genotypes
  • Realized genomic relationships matrix and GBLUP
  • Marker-trait associations
  • Genome-wide selection

The exercises will demonstrate use of ASReml, R packages, and additional tools for data analysis. Some familiarity with R syntax will be expected. A temporary free license for ASReml will available at the time of workshop.

About the Workshop:

  • The workshop will be taught at an intermediate to advanced level. Participants are expected to have some understanding of the theory of mixed models.
  • This is a hands-on workshop. Participants are expected to work on exercises related to crops, animal and forest trees. You may bring your own laptop and your own data to work on after lectures.
  • Workshop format: Four sets of lecture + exercise per day. Each set will be a about 30-minute lecture and 60-minute exercise. See example below.

  • 08:30 – 10:00 – Lecture 1
