Genomic regions involved in yield potential detected by genome-wide association analysis in Japanese high-yielding rice cultivars. Oryza sativa

High-yielding cultivars of rice (Oryza sativa L.) have been developed in Japan from crosses between overseas indica and domestic japonica cultivars. We used a custom SNP set to identify introgressed chromosomal regions in a set of high-yielding Japanese rice cultivars, and we performed an association study to identify genome regions associated with yield.
