| Analysis of Experiments using ASReml-R
(with emphasis on breeding trials)
We are delighted to announce a 2 day ASReml-R course which is being held in Davis, California, USA on 14/15 September 2011.
Summary details:
- Date: 14/15th September 2011
- Location: Davis, California, USA
- Duration: 2 days
- Time: Start 9am, Finish 5pm
- Price: $895 USD for both days (includes all materials and lunches)
Who Should Attend
This workshop is aimed to scientist/practitioners and researchers who are interested in analyzing complex datasets by fitting linear mixed models. The workshop requires participants to have some experience of breeding programs as well as design and analysis of experiments. After the workshop the participants should be able to understand the use of ASReml-R and to analyze most biological experiments and more specifically, study breeding trials for single or multiple sites or experiments. Participants should also be able to extract relevant genetic parameters and generate rankings of genotypes based on breeding value prediction to assist decisions in their genetic improvement programs.
Course Aim
This workshop will focus on the fundamentals of using the ASReml-R 3 version, which is used within the statistical package R, for the analysis of genetic data arising mainly from agricultural and forestry breeding programs. ASReml-R is statistical software that fits linear mixed models using REML methodology and predicts BLUP values. Genetic concepts required for the construction of appropriate linear models will be addressed together with understanding ASReml-R inputting and manipulating data, proper construction/specification of linear models (and their variance structure). In addition, some extensions on the use of complex statistical designs and on genetical/biological interpretation of the results will be discussed. This workshop is strongly oriented to the practical aspect of analysis of real, complex, and messy datasets. It is recommended to have some prior understanding of linear mixed model methodology and genetic theory. The main topics discussed will be univariate analyses of animal (individual) model, half-sib families, and full-sib families together with presentation of multivariate, multi-environment studies. Introduction to generalised linear mixed models or spatial analysis will be optional.
