Synopsis of seminar:

For decades, animal breeders have used genetic relationships (pedigrees) in their analysis of phenotypic data; the rate of genetic progress was improved since parents were selected for "estimated breeding value" (additive genetic effects) rather then "estimated genetic value" (additive and non-additive effects).  Now, animal breeders are incorporating whole genome molecular markers in their phenotypic analyses, which has accelerated genetic progress and enabled the identification of QTLs and genes for valuable economic traits.  Plant breeding involves more complex systems of field trials with replicated entries, and often there is a large impact of genotype x environment (GxE) interaction on the performance of individuals.   Recently, biometrical analyses have been developed to analyse multi-environment trials (MET) with factor analytic (FA) modelling of GxE effects.  We analysed oil and yield data across a series of canola trials in southern Australia by MET/FA modelling with and without pedigree information, and showed the benefit of genetic relationships to improve estimates of additive and non-additive genetic value of lines in various clusters of environments.  The MET/FA analysis will eventually incorporate whole genome molecular markers, which will accelerate genetic progress accompanied by discovery of important genes for adaptation to regional environments.  This will begin the era of the "silicon revolution" in plant breeding.
