Abstract
稉型水稻品種「台農86號」係行政院農業委員會農業試驗所嘉義農業試驗分所於2014 年第1 期作以抗病蟲且高產水稻品種「台農84號」為母本，低蛋白質含量水稻品種「台農82號」為父本進行雜交，在F2–F4世代以修飾後混合法進行分離後裔選拔，F5世代以後經譜系法進行品系選拔，於2018年第1期作擇優選出嘉農育1061008號參加區域試驗及特性檢定，2021年申請命名通過。本品種產量高且穩定、外觀米質與米飯食味優良，對於葉稻熱病抗性等級介於2–4級之間，褐飛蝨抗性等級分別介於3–5級之間，相較於兩親本「台農84號」第2期作低產及「台農82號」易感稻熱病等缺點均有所相當的改善。
New Japonica rice cultivar, ‘Tainung 86’, was hybridized by ‘Tainung 84’, a female parent with high grain yield and resistance to diseases and insects, and ‘Tainung 82’, a male parent with low grain protein in the 1st crop season of 2014 in Chiayi branch station, Taiwan Agricultural Research Institute (TARI). From F2–F4 generations, modified bulk method was implemented to select separated lines, and pedigree method was applied to select new separated lines after F5 generations. New rice line, Chianung-yu 1061008, was selected to take part in regional trial and particular character test in the 1st crop season of 2018. It was formally named ‘Tainung 86’ by a review committee in 2021. ‘Tainung 86’ has stable grain yield, good grain appearance and eating quality, moderately resistance to leaf blast and brown planthopper. It also improved the weaknesses from female parent-low grain yield and susceptibility to bacterial leaf blight, and male parent-susceptibility to rice blast.
