Photosynthetic efficiency, a key trait that determines yield potential in rice, is quantitatively regulated by multiple genes. Utilization of valuable genetic resources hidden in wild rice is an effective way to improve rice photosynthesis and yield potential. In this study, 152 backcross inbred lines derived from wild rice Oryza longistaminata were explored for QTL mapping of photosynthetic rate (Pn) and biomass (BM) in natural fields. Five novel QTLs for Pn and seven QTLs for BM or daily biomass (DBM) derived from O. longistaminata were identified. One of these QTLs, qPn8.1, could significantly improve Pn and was located in a 68-kb region containing only 11 candidate genes. Meanwhile, qBM1.1 and qDBM1.1 for BM and DBM on chromosome 1 were overlapped with qPn1.1 for Pn from 9311, and could affect both Pn and BM in natural fields. These QTLs identified in O. longistaminata may provide a novel alternative to explore new genes and resources for yield potentiality, highlighting the important role of wild rice in rice breeding programs. |
