Abstract

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.
