本研究為開發冷凍加工用矮性菜豆（Phaseolus vulgaris L.）自有品種，並了解其栽培適期，以開拓冷凍蔬菜外銷市場。矮性菜豆‘台中6號’為以‘Vivid’為母本、‘Sonnet’為父本雜交，F_2至F_4世代之分離族群以單株純系選拔，F_5至F_7世代以混合選拔法，後經品系試驗及性狀檢定選育出嫩莢用之固定品種，播種至開花日為35～40天、55～65天可採收，其直立性與結莢性佳、莢色濃綠、無筋絲，莢直徑7～8 mm，符合冷凍加工規格。另栽培適期試驗結果建議，矮性菜豆於中部地區適當種植期為9月至隔年2月份，3月份後種植因環境溫度逐漸升高，結莢性差且果莢品質不佳。

In order to expand exported frozen vegetable market, the aim of this study was to breed new bush common bean (Phaseolus vulgaris L.) cultivar for frozen processing and understand its optimal cultivation season. New bush common bean 'Taichung No. 6' was crossed from the cultivar 'Vivid' and 'Sonnet', followed by pure -line selection at F_2-F_4 and mass selection at F_5-F_7 generations. After that, line trails as well as characteristic test were conducted then bred as an open-pollinated cultivar for fresh pod use. The traits of bush common bean 'Taichung No. 6' included upright shoot, excellent podding, dark green, stingless, and 7 to 8 mm-diameter of pod. Those traits fit the requirements for frozen processing. It took about 35 to 40 days from sowing to flowering and 55 to 65 days to harvesting. For cultivation in central Taiwan, the optimal sowing season of this cultivar is suggested from September until next February. The pod setting and quality is poor sowing in March and after due to high temperature.
