為提高薏苡單位面積產量，1999年春作採用臺中1號為母本，奧羽3號為父本，進行雜交，雜交後代利用混合法選拔於2001年春作（F3）開始選拔，歷經5世代後代分離及選拔，於2003年秋作選出優良系統TC92-9，參加2004年新品系初級比較試驗及2005～2006年新品系比較試驗，由於農藝性狀及產量表現優越，選出定名為臺中育17號，參加2006～2007年新品系區域試驗，並進行新品系栽培法試驗、品質檢定及抗病蟲檢定，因具有強稈、耐倒伏、抗葉枯病、每平方公尺枝數較多、稔實率高、千粒重較重、產量高及富含營養成分等特性，於2008年7月15日獲准命名為臺中3號推廣之。

In order to increase the yield of job's-tears in Taiwan, elite hybrid progenies of the crossing Taichung No. 1 (maternal parent) with Oou No. 3 (paternal parent) were selected through mass selection procedure. Line TC92-9 was selected for new lines primary trials in 2004 and for new lines comparison trials in 2005-2006. Due to its superior agronomic performance and high yield, it was designated as Taichung Sel. No. 17 and further put in regional trial in 2006-2007. Cultivation experiment, quality determination, and pest resistant tests were subsequently conducted during 2006-2007. The results showed that line possesses superior agronomic characteristics, including strong culm, lodging resistant, high grain number per plant, higher percentage of fertile grain, high 1000 grains weight, and higher yield. The grain crude fat, ash, and coixenolide of this line were higher than the control line Taichung No. 1. The line was approved and registered as Taichung No. 3 in July 15, 2008 and released to farmers.
