(65(4):430-438) Breeding of a New Indica Purple Rice Variety ‘Tainung Sen Glutinous 24’

「台農秈糯24 號」(‘Tainung Sen Glutinous 24’; ‘TNGSG 24’) 係行政院農業委員會農業試驗所嘉義農業試驗分所於1990 年以品系台秈糯育744 號為母本，與泰國引進之「秈黑糯」品種進行雜交選育而成，2011 年命名為「台農秈糯24 號」並提出申請植物品種權，2013 年正式取得植物品種權。本品種為秈型糯稻，其糙米外觀呈深紫黑色，對稻熱病抗性不穩定，對褐飛蝨為中抗級。生育日數第1 期作為135 d，第2 期作為110 d，屬中晚熟品種；單位面積產量第1 期作為5,455 kg ha-1，第2 期作為4,600 kg ha-1，分別比對照品種「台中秈糯1 號」減產11.2% 及增產15.0%；糙米率及完整米率均略低於對照品種「台中秈糯1 號」與「台秈糯2 號」，食味品質則與兩對照品種相近。富含維生素、礦物質元素、葉酸與總多元酚等營養及抗氧化成分，清除自由基DPPH 之抗氧化能力是對照品種「台農秈糯21 號」的11.4 倍。本品種屬於有色稻米，未來可做為養生保健食品及各種米食加工等多元化利用之品種。 ‘Tainung Sen Glutinous 24’ (‘TNGSG 24’) was crossed between ‘Tai Sen Glutinous Yu 744 (TSGY 744)’, a female parent, and ‘Sen-Hei Nuo’, a male parent from Thailand in 1990, at Chiayi Branch Station of Taiwan Agricultural Research Institute (TARI). It was given the name of ‘TNGSG 24’ and was presented to apply plant variety right in 2011. It was granted the plant variety right certificate in 2013. ‘TNGSG 24’ is an indica rice. The appearance of brown rice is deep purple. The resistance of rice blast was unstable. The resistance to brown planthopper was ranked as medium. The growing days of the 1st cropping season was about 135 d, and the 2nd cropping season was about 110 d. It belongs to mid-late maturity. The grain yield of ‘TNGSG 24’ was 5,455 kg ha-1 in the 1st cropping season, and was 4,600 kg ha-1 in the 2nd cropping season, which was 11.2% lower and 15.0% higher than that of CK, respectively. Brown rice and the rate of head rice are slightly lower than that of CK, but cooking and eating quality are similar to CK. ‘TNGSG 24’ richly contains vitamin, mineral, folic acid, polyphenol, and some antioxidant ingredients. The antioxidant ability of 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging for ‘TNGSG 24’ is 11.4 times higher than that of CK. The variety is a colored rice that could be used for processed products in the future
