Résumé
The completed gnome sequences of rice subspecies, indica and japonica, as well as the characterization of a large number of important trait-related genes, laid a sound foundation for genomics-based breeding. Re-sequencing thousands of rice germplasm accessions by next-generation sequencing technologies provided breeders with enormous amount of sequences for genetic marker development. Additionally, high-throughput marker assays were recently made available to breeders, and subsequently large-scale genotyping became economically and timely feasible. All of these together speeded up the development and implementation of genomics-based breeding. In the foreseeable future, genomics-based breeding will potentially become a common practice in rice variety development. This chapter reviews the recent advances in high-throughput genetic marker development and assay technologies and also provides a few examples of strategies for practicing genomics-based breeding in rice.
