摘要

臺中195號(Taichung 195, TC195)係由行政院農業委員會臺中區農業改良場於2012年6月育成的稉稻品種，全生育日數在第一期作平均為132天，而第二期作平均為113天；經2年4期作區域試驗中之平均稻穀公頃產量第一期作為7,707 kg，明顯較對照的台稉9號增產13.5%，第二期僅較台稉9號增產1.4%，顯示臺中195號稻穀產量之表現較對照品種台稉9號高產。綜合4次的食味品評，顯示臺中195號米飯的外觀較佳、硬度較軟及總評較佳。此外，臺中195號之抗白背飛蝨表現較台稉9號佳，平均為中抗等級；抗倒伏能力良好且脫粒率中等，適合機械收穫。唯臺中195號於第二期作之耐寒性較弱，需注意第二期作不宜過晚種植；對稻熱病、紋枯病、白葉枯病、縞葉枯病及斑飛蝨等病蟲害並不具良好抗性，栽培時應注意適時防治。
