為提高台灣薏苡單位面積產量，於民國71年自日本引進6個品系進行觀察試驗，發現尾花澤在來具有高產潛能，但株高較高，分蘗數較少，因此用混合選種法進行品系選拔，選出74-T5優良品系參加新品系高級產量比較試驗，由於農藝性狀及產量表現優異，乃以台中選育5號名稱參加新品系區域試驗及地方試作，並進行抗葉枯病及品質檢定，因具有強稈、耐倒伏、耐旱、高產及適應性廣等特性，於84年1月獲准登記命名為台中1號及推廣。

Job's-tear is used as a healthy food of high economic value in many Asian countries. Six lines of job's-tear were introduced from Japan in 1982 and evaluated for their adaptability in the spring crop of 1983. One of the introduced lines, Obanazawa Native, was high in yield potential but exhibited inferior agronomic characteristics in plant height and tillering ability. Accordingly, mass selection method was employed to improve the lines for four consecutive crops (two spring and two fall crops) from 1983 to 1985. A superior line, 74-T5 was selected and later renamed as Taichung Selection Yu No. 5. Advanced, regional, and local yield trials, as well as chemical analysis and other field tests were then conducted between 1986 and 1993. The combined results indicated that Taichung Selection Yu No. 5 possessed strong stem, resistance to lodging, drought tolerance, high yield and wide adaptability. The new line was therefore officially registered as job's-tear cultivar Taichung No. 1 in January, 1995 and released to farmers for commercial production.
