摘要

台中194號（Taichung 194，TC194）係由臺中區農業改良場於2009年12月育成的稉稻品種，並於2015年10月2日取得植物品種權，其全生育日數第一期作平均為134天，第二期作平均為109天；區域試驗平均公頃稻穀產量第一期作為5,763 kg，第二期作為3,249 kg，雖較對照的台稉9號分別減產3.8%及9.9%，但其差異未達顯著水準，顯示台中194號稻穀產量之表現略低於對照品種台稉9號。在食味品評方面，台中194號具有較佳的米飯外觀、口味及總評較佳，並具有香味，顯示本品種具有極佳的食味品質。此外，台中194號米粒外觀品質良好、抗倒伏能力良好且脫粒率為中等，適合機械收穫，對稻熱病、斑飛蝨與白背飛蝨等病蟲害抵抗性良好。惟台中194號對紋枯病、白葉枯病、縞葉枯病與褐飛蝨等病蟲害並不具良好抗性，栽培時應注意適時防治。
