We re-sequenced and phenotyped 2,839 rice hybrid cultivars and 9,839 F2 individuals from elite hybrids. Based on the dataset, the genetic improvement during rice hybrid breeding was investigated, and the genetic basis underlying strong heterosis was quantitatively evaluated. Furthermore, a genomic selection model was constructed to optimize heterotic combinations.
