摘要

葉菜甘藷「桃園二號」，原來品系代號為H66，係1983年從多向雜交族群第五世代後裔中選出，歷經新品系比較試驗、區域試驗、栽培密度及肥料試驗、病蟲害調查、成分分析及食味品評等試驗，於1998年1月經台灣省農林廳聘請專家學者組成新品種登記命名審查小組審查通過，正式命名為葉菜甘藷「桃園二號」，其主要特性為芽梢產量高，再生力強且收穫期長，年採收9次的芽梢總產量為2,281 kg/10a。芽梢食用品質佳，不需去除芽梢表皮即可煮食，蒸煮後不褐變，質地細，無苦澀味且適口性佳。夏季高溫生育快速，病蟲害少，且營養豐富，是一種非常適合夏季栽培的蔬菜品種，又枝蔓頂部均向上生長，適於機械收穫。

The new vegetable sweet potato cultivar ”Taoyuan 2” was originated from the clone of H66 selected from the 5th generation of polycross population in 1983. After a series observation test, local yield and regional yield trials, the new cultivar was registered and released for commercial production in 1998 due to its' superior performance with high yield and good quality for used as leafy vegetable. The characteristics of ”Taoyuan 2” are summarized as follow:1. The shoot yield harvested 9 times a year and totaled 2,281 kg/10a due to the high ratooning ability of ”Taoyuan 2”.2. The shoot of ”Taoyuan 2” can be cooked without peeling off the epidermis. It does not turn brownish after cooking, and it tastes very good with good texture and no bitter taste.3. ”Taoyuan 2” is suitable for growing in high-temperature environments and offers a newly developed leafy vegetable source in summer.4. ”Taoyuan 2” with semi-erect shoot is suitable for harvesting with combine machine.
