Significance In eukaryotes, meiotic recombination shuffles genetic information at each generation, making each offspring unique. In addition to its key role in heredity and evolution, this gene reshuffling is central in plant and animal breeding, which relies on the ability to combine desired alleles. However, the number of recombination events by generation is low, limiting the power of breeding programs. Here we showed that meiotic recombination can be massively increased in hybrid plants, up to almost eightfold. This opens the possibility of manipulating recombination to enhance the efficiency of plant breeding programs, which is important as we face the double challenge of ensuring food security while preserving natural resources.
