Breeding an Early-maturing Hybrid Rice, Quanyou 1093

A new early-maturing restores line, Fuhui 1093, was developed by crossing the widely cultivated early-maturing restorer line, Minghui 82, with the late-maturing japonica/indica restorer hybrid, Zhi 8. Subsequently, it was crossed with the 3-line male sterile, Quanfeng A, to obtain Qunanyou 1093. The final hybrid exhibited many desirable characteristics including large stem-girth, strong tillering, large panicles with numerous spikelets, desirable color change during mycelium ripening, and high grain yield. The average grain yield in two year-long, production trials on the new variety was 5.53% higher than that of CK. It has been certified by Fujian Crop Variety Evaluation Committees in 2014.
