AbstractThe breeding process of Huijingnuo OO9 wasintroduced，itsparental sources，selection process， characteristics，and high yield cultivation techniques were summarized.Developed through composite hybridization of Wankennuo 1//Wuyunjing 24/Zhendao14，Huijingnuo O09 isa medium-japonica glutinous rice variety，approved by he Anhui Crop Variety Approval Commitee in 2024（Wanshendao 2024L066）.During the2020-2021 regional and production trials，its average yield ranged from 9.72 to 10.28t/hm2 ，representing a 5.88 % 1 8.21% increase over the control variety （Dangjing No.8）.The variety exhibits excellent grain quality， with an amylose content of 2.0% and high gelconsistency.Resistanceevaluations indicate moderatesusceptibilitytorice blastandbacterial leaf blight，and susceptibilitytofalse smut.Keycultivation techniques includemechanicalor manual transplanting，with recommended practices such as sun-drying，soaking，and germinating seeds before sowing.For mechanical transplanting，sowing in lateMayis advised，with aplanting density of 225000-270000hills/hm2 .Fertilization should emphasize base fertilizer （accounting for over 60% of total nitrogen application）， supplemented by timely topdressing at the reviving，tillring，and panicleinitiationstages.Irigationshouldfollowtheprincipleof“shallow waterfortransplanting，shallow-wet conditions fortilering，timelyfielddrying，andalternatingdryand wetconditions”，with watercutoffapproximately 7 daysbefore harvest.Pestand disease control should prioritizeprevention，implementing integrated management targeting major weeds，pests，and diseases at diferent growth stages.This study provides valuable references forfurther promotion and cultivation of Huijingnuo 009.
