　　本研究之育種目標在培育出在夏季高溫期可正常結球、葉肉質嫩及無或低辛辣味的甘藍品種，提供農民在平地夏季栽種，以求在夏季穩定甘藍生產並遏阻在高冷地區栽種。試驗結果顯示一代雜交品系“試交三號”整齊度高，葉球顏色翠綠，結球緊密呈扁橢圓形，夏天栽培平均葉球重約1.5公斤，秋作在1.8公斤以上，具耐熱性及產量高，適合於台灣南部平地於7月底(晚夏)至翌年5月初(早夏)栽種。種子生產評估試驗結果顯示每0.1公頃約可採種約7.7∼9.2公斤。該品系也耐貯藏，以溫度1℃，相對濕度90%-95%貯藏1個月，外葉仍可維持翠綠，然不抗黑腐病及軟腐病，夏季栽培需加強病害防治。該品系已於94年10月7日通農委會作物新品種命名審查委員會審議通過命為甘藍「台南1號」，商品名為「夏初秋」。新品種的育成有利於減少夏季山區栽種甘藍菜之面積，延長平地栽種甘藍適期，並可進一步取代現行栽培品種初秋，朝向甘藍品種國產化之目標。

The Breeding of a New Cabbage Variety "Tainan No.1"

Abstract

　　This is aimed at obtaining a heat tolerant cabbage varieties for the farmers to grow in the low land areas in summer season which may ease the shortage of leaf vegetable in the summer season and reduce the plantation of cabbage at the high mountain areas. Results showed that Tainan Test No. 3 is very promising with head uniformity in nice green color and flat and oval shape. It can be grown from late summer in July to early summer in May of the next year in the low land areas with a average weight per head at 1.5 - 1.8 Kg. Seed production tests showed that 0.1 hectare can set seeds as much as 7.7 – 9.2 Kg. The harvested cabbage can be stored for 1 month at 1℃ under 90-95% of relative humidity. However, it is not resistant to soft-rot and black-rot diseases. Therefore, proper control measures should be taken in the grown season. The line has passed the naming evaluation committee for crop new varieties of Council of Agriculture on 7 October 2005, and named “Tainan No. 1”.
