BREEDING FOR QUANTITATIVE TRAITS

This is not an exhaustive course about plant breeding, but a focus on a common method (reciprocal recurrent selection) and on the state-of-the-art method of marker assisted selection for quantitative traits (genomic selection), with a preliminary presentation of the basics necessary to understand them.

lecture and practical work – requirements (for the practical work): computer, R software, knowledge of R download files here (ver. feb 2018)

o   PART 1 – Basic concepts of genomics (chromosomes, genes, markers), quantitative genetics and breeding (mass selection, RRS, experimental designs)

o   PART 2 – Resemblance between relatives 

o   PART 3 – Linear mixed model,  heritability,  selection accuracy, genetic gain

o   PART 4 – Genomic selection
