Rice Research Institute, Fujian Academy of Agricultural Sciences, Fuzou, Fujian 350018, China

摘要

摘要: 目的用优质抗病常规稻与生产上大面积利用的强恢复系杂交选育出优质抗病恢复系，再与优质不育系组配选育出优质抗病杂交稻新品种。方法以优质抗病常规稻华航丝苗为母本，与强恢复系明恢86杂交，杂种F₁代再与强恢复系蜀恢527复交，后代经多年在福建上杭茶地、将乐黄潭等自然稻瘟病区及福建省农业科学院植物保护研究所等地进行稻瘟病抗性鉴定，筛选出的优良单株连续多年在福建沙县、海南反复加代定向培育和逐代稳定，于2010年育成株叶形态好、配合力高、中抗稻瘟病、米质优的恢复系福恢2165。2014年用福恢2165与优质长粒型三系不育系泰丰A配组，经2015年的品比试验，2016-2017年的区域试验和生产试验，育成了优质三系杂交晚稻新组合泰优2165。结果泰优2165在两年区域试验中的平均产量达7815.83 kg·hm^-2，比对照品种（宜优673）增产2.81%，丰产性、稳产性表现好，中感（MS）稻瘟病，米质达部颁二等优质米标准。于2018年通过福建省农作物品种审定（闽审稻20180016）。结论泰优2165具有产量高、米质优、商品性和抗病性均好等优点，可作为福建省的主推优质稻品种。

Abstract: Objective To breed a high-quality, disease-resistant, late-season restorer line of hybrid rice. Method By multiple-crossing between the strong restorer line, Shuhui 527, and F1 hybrid of the conventional rice HHSM (female parent) and the strong restorer line Minghui 86 (male parent), Fuhui 2165 with desirable plant and leaf morphologies and high combining ability was developed in 2010. Through multiple screenings for rice blast resistance in the natural disease-prone fields, such as Chadi of Shanghang and Huangtan of Jiangle, as well as the indoor blast verification test at the Plant Protection Institute of Fujian Academy of Agricultural Sciences, Fuhui 2165 was continually improved using the chosen and resistant progenies for directional cultivation and generational stabilization in the successive years in Shaxian and Hainan. From the combination of Fuhui 2165 and the fine quality long-grain CMS line, Taifeng A, which was bred by the Rice research Institute of Guangdong Academy of Agricultural Sciences, the 3-line hybrid late-season rice combination Taiyou 2165 was obtained in 2014. Subsequently, it was submitted to and passed the comparative trial in 2015 and two-year regional tests as well as the production tests in 2016-2017. Result The average yield of Taiyou 2165 in the two-year regional tests reached 7, 815.83 kg·hm^-2, which was 2.81% higher than that of the reference variety, Yiyou 673. It displayed a medium infection susceptibility toward the rice blast and was given a second-grade high quality rice status issued by the Ministry of Agriculture. In 2018, Taifyou 2165 was certified by the Fujian Province Crop Variety Approval Committee. Conclusion Taifyou 2165 demonstrated a high and stable yield, excellent grain quality, strong disease resistance, and promising marketing potential, and therefore, was recommended for promotion in Fujian.
