Jennifer Kling, Oregon State University; Heather L. Merk, The Ohio State University
During this webinar, Dr. Jennifer Kling provides an introduction to the augmented experimental design and analyzes data collected for her meadowfoam breeding program at Oregon State University.
This one hour webinar has been divided into eight videos, which are listed in order on this webpage. The ninth video is the full webinar. The powerpoint slides (in pdf format), sample data files, and SAS code are provided at the bottom of the page.
By the end of this webinar you should be able to:
- List the essential features of an augmented experimental design
- State when and why a plant breeder may wish to use an augmented experimental design
- Describe when genotypes should be treated as fixed effects and when they should be treated as random effects
- Analyze the sample data set when the new entries are treated as fixed effects and random effects
- Part 1 – Introduction to augmented designs
- Part 2 – Background to sample analysis using Dr. Jennifer Kling’s meadowfoam breeding program
- Part 3 – Experiment design and field layout
- Part 4 – Analysis treating genotypes as fixed
- Part 5 – Analysis treating genotypes as random
- Part 6 – Introduction to two way control of heterogeneity and more complex analyses
- Part 7 – Software and resources for augmented design
- Part 8 – Question and answer session

About the Presenter
Dr. Kling is a plant breeder who teaches experimental design to graduate students in Agriculture at Oregon State University. She has considerable experience in the application of recurrent selection methods to improve yield, stress tolerance, and disease and insect resistance in cross-pollinating crops (maize and meadowfoam). She enjoys analyzing data and was the data curator for the Barley Coordinated Agricultural Project (Barley CAP). Dr. Kling received a Bachelors degree in Crop Science from Oregon State University and a Masters in Agronomy from the University of Nebraska-Lincoln. She obtained a Ph.D. in Genetics with a minor in Statistics from North Carolina State University.
