台中秈197號(Taichung sen 197, TCS197)係由臺中區農業改良場於2017年6月命名的秈稻品種，生育日數在第一期作平均為127天，第二期作109天，區域試驗平均公頃稻穀產量在第一期作為7,239 kg，第二期作3,611 kg，其生育日數及平均公頃稻穀產量與對照品種台中秈17號(TCS17)相近。若與對照品種台中秈17號比較其農藝特性，台中秈197號碾米品質佳、米粒外觀品質良好、抗倒伏能力良好且脫粒率為難至中等，適合機械收穫，對稻熱病、縞葉枯病及白背飛蝨等病蟲害抵抗性良好。惟台中秈197號生育後期耐寒性不佳，二期作栽培勿晚於立秋節氣種植，以避免成熟期遭受低溫的危害，此外，本品種對白葉枯病、紋枯病及褐飛蝨抵抗性不佳，應注意適時防治。

'Taichung sen 197', an indica rice variety, has been nominated and released in June, 2016. The growth durations of this variety are 127 and 109 days in the 1^(st) and 2^(nd) cropping season, and the average grain yield is 7,239 kg/ha in the 1^(st) and 3,611 kg/ha in the 2^(nd) cropping season, respectively. Both of growth duration and average grain yield of TCS197 are similar to the control variety, Taichung sen 17. In addition, TCS197 has other good traits such as good milling quality, grain appearance, culm strength and moderate panicle threshability, and resistant to blast and small brown planthoppers. On the other hand, TCS197 is sensitive to cold temperature, it is suggested that transplanting at the 2^(nd) cropping season should not be later than the beginning of autumn. Besides, this variety is not resistant to bacterial leaf blight, sheath blight and brown planthopper, therefore timely prevention practices during cultivation is necessary.
