稉稻台農75號於2006年第二期作完成命名登記,為國內第一個利用化學誘變劑疊氮化鈉誘變台農67號之後代。該品種具有父母本雙重優點,米質優良且對稻熱病、褐飛蝨、白背飛蝨及斑飛蝨等多種主要病蟲害具強烈抗性。母本TM6自化學誘變庫中選出,具有廣幅抗稻熱病、褐飛蝨三型生物小種、白背飛蝨及斑飛蝨等特性;父本為良質米台稉2號。父母親本於1995年雜交,歷經10年選拔與多項試驗檢定而選出台農75號,其稻榖產量與豐產對照品種(台農67號)之差異不顯著,米飯食味與良質米對照品種(台稉9號)無明顯差異,且在室溫下儲藏3個月後,食味品質無太大改變。由於該品種對主要的病蟲害具有穩定的抗性,可以不使用農藥,適合有機農業栽培。
A new japonica type rice variety, Tainung No.75, was registered in the second crop season of 2006. The variety, possessing the merits of both parents, has good eating quality and is resistant to multipests including rice blast, brown planthopper, white backed planthopper and small brown planthopper. The female parent TKM, a mutated progeny of rice Tainung No.67 induced by mutagen sodium azide, has a wide range of resistance to rice blast, brown planthopper type I, II, and III, white backed planthopper, and small brown planthopper. The male parent Taikeng No.2 has excellent eating quality. The new rice variety was developed after 10-year selection and evaluation. There was no significance difference between rice Tainung No.75 and rice Tainung No.67 (variety for yield check) in grain yield, and no significant difference between Tainung No.75 and Tainkeng No.9 (variety for panel check) in panel test. There was no obvious change in eating quality when the grain was stored at room temperature for 3 months. The variety is suitable for organic cultivation due to its traits strong resistance to multi-major pests.
