The two-line rice hybrid “Super 1000”(GX24S× R900) represents a major landmark
achievement of breeding for super-hybrid rice in China. However, both male parent R900 …

A major phenomenon hindering development of inter-subspecific rice hybrids is the 'hybrid
sterility'observed in indica× japonica (IJ) crosses. We had successfully transferred wide …

Soil salinity is one of the major abiotic stresses limiting rice growth. Hybrids outperform their
parents in salt tolerance in rice, while its mechanism is not completely understood. In this …
