摘要

台農74號係農業試驗所嘉義農業試驗分所於1998年第1期作以台農71號為母本，台稉育30904號為父本進行雜交，歷經分離世代選拔、初、高級產量比較試驗、區域試驗、稻米品質分析、食味檢定、氮肥效應試驗、稻穀儲藏試驗及各項特性檢定後，於2006年11月14日經「行政院農業委員會農業試驗所植物品種命名審議委員會」審查通過，正式命名推廣。台農74號為稉稻香米品種，其米粒外觀晶瑩剔透，米飯具有清雅之芋頭香味，食用品質優良，稻穀產量高，耐儲藏性佳，脫粒性適中，穗上發芽率及耐倒伏性較台農71號為佳，對於稻熱病抵抗性不穩定，中抗白背飛蝨及斑飛蝨。本品種為中晚熟品種，其生育日數第1期作為120天，第2期作為106天；平均稻穀產量第1期作為7104kg/ha，第2期作為5362kg/ha，適合全台各地區栽培。在2009年台農74號栽培面積已逾350ha，且在市面上已有「雪山香米」及「香美人」等新品牌上市；並榮獲2008年日本「第十屆日本米．食味鑑定國際賽」金賞獎，獲選為「最適合咖哩烹調的米」。

A new Japonica (Keng) type aromatic rice variety, Tainung 74, was developed by the Chiayi Agricultural Experiment Branch, Taiwan Agricultural Research Institute (TARI), COA. The experimental designation of this variety was Chianung yu 901082, and was selected from a progeny of a cross, Tainung 71 and Taikeng yu 30904. Through nine years breeding program, including progeny selection, preliminary yield trial, advanced yield trial, regional yield trial, quality evaluation, panel test, nitrogen response, and storage trial, the Chianung yu 901082 has demonstrated its stable productivity and good grain quality. It was formally registered as Tainung 74 by the Committee of Registration for New Plant Variety of the TARI, COA, Excutive Yuan, on November 14, 2006. The variety possess excellent grain appearance and high eating quality with taro scented flavor, higher yield potential, lower on-panicle sprouting and lodging incidence than Tainung 71. Tainung 74 is moderately resistant to white backed planthopper and smaller brown planthopper, but its resistance to blast disease is unstable. Growth duration is 120 and 106 days, and the average grain yield is 7104 kg/ha and 5362 kg/ha in the first and second crop season, respectively. The variety is recommened to be cultivated in whole rice regions in Taiwan, and the total cultivated area have reached more than 350 hectares in 2009. Several commercial brands, such as 'Snow mountain aromatic rice' and 'Aromatic beauity' etc. for the rice have been named in the market, Furthermore, Tainung 74 had got a golden medal prize at the 10th International Contest on Rice Taste Evaluation of Japan in 2008, and was selected as the best variety for cooking curry rice.
