早籼杂交稻全优1093的选育

Breeding an Early-maturing Hybrid Rice, Quanyou 1093

  • 摘要: 利用早/晚恢杂交的方法,将生产上大面积应用的早熟恢复系明恢82与籼粳交迟熟恢复系育种材料制8杂交,选育出早熟恢复系福恢1093,并与抗稻瘟病、高异交率三系不育系全丰A配组育成早籼杂交稻新品种全优1093。该品种经多年多点示范,表现出植株茎秆粗壮、分蘖力强、穗大粒多、产量高、后期转色好等优点,2年区试平均产量比对照增产5.53%,于2014年通过福建省农作物品种审定委员会审定(闽审稻2014004)。

     

    Abstract: 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.
