摘要

為提高國產薏苡、蕎麥單位面積產量及食用紅甘蔗品質與產量，本場於民國88年至91年進行薏苡、蕎麥及食用紅甘蔗新品系產量比較試驗並於民國90年進行食用紅甘蔗新品系區域試驗。結果薏苡選出全農系分、京都旭、中里在來、岡山3號及鳩力等5品系，晉升新品系區域試驗，其中以全農系分之表現最佳，具有抗葉枯病、抗倒伏、良質及高產等特性。蕎麥選出TARI 40051、50039、50041、CIFA 38、39及九江苦蕎等6品系晉升新品系區域試驗，其中以九江苦蕎之表現最佳，具有半矮性株高、中熟及高產等特性，每公頃產量3,088 kg，比臺中1號增加35.9%，食用紅甘蔗選出臺中育2、5、6、9、10號等5品系參加90年新品系區域試驗，結果以臺中育10號之表現最佳，具有蔗莖長、中間5節長度長、第5節節間直徑粗、總可溶性固形物及產量高等特性，每公頃蔗莖產量高達124,138 kg，比埔里地方種增加17.7%。
