Abstract excerpt
Hybrid rice has made significant contributions to global food security. However, the efficient utilization of landraces to further enhance heterosis remains a key challenge in rice breeding. In this study, we collected a set of 1,392 landraces and 696 hybrid rice parental lines. A total of 770 hybrid combinations were constructed by crossing 517 accessions selected from 2088 rice accessions, and seven key...
