Abstract

Modern agriculture must ensure food security in a context of climate change that will lower yields. A better understanding of the factors controlling meiotic recombination could pave the way to modifying the number and distribution of crossing-over, which would allow a more precise localization of genetic factors controlling agronomic traits, and facilitate gene pyramiding in selection programs. During my thesis, I developed a method for high-throughput measurement of recombination rates in the yeast Saccharomyces cerevisiae. This allowed me to study the diversity of recombination and interference in a collection of 24 strains representing most of the diversity of the species, as well as within a five-parent di-allele design. The results sh...
