SEMINAR: genomic prediction in plant breeding programs:
|genomic prediction in plant breeding programs: : estimating heritability and predictive accuracy of genomic prediction in plant breeding programs
Heritability is often used by plant breeders and geneticists as a measure of a trialís precision, or the
precision of a series of trials. For computing its main use is the response to selection.
Most formulas proposed for calculating heritability implicitly assume balanced data and independent
genotypic effects. While both of these assumptions are often violated in plant breeding trials, equations
assuming balanced data are still in common usage.
This talk reviews various approaches to assessing heritability and derived quantities for unbalanced plant
breeding trial data.
Furthermore, Professor Piepho will also discuss the related problem of assessing predictive accuracy in genomic selection.
