葉用芥藍新品種「鳳山1 號」之育成

為育成早生耐熱、口感甜嫩之芥藍雜交新品種，行政院農業委員會農業試驗所鳳山熱帶園藝試驗分所評估所育成芥藍自交系之株型、展幅、葉形、分枝數、生育日數及耐熱性。先篩選出「包心美芥藍」及「白花特大心」具耐熱及優良性狀的兩個自交系，並透過雜交育種法，育成一代雜交種，進行品系比較試驗及區域試驗，最後選出芥藍雜交新品系16-1232。16-1232 無論是新鮮植株或加熱後之總糖含量均顯著高於對照品種「翠津」，食用明顯略帶甜味。有機酸中，16-1232 以檸檬酸的含量顯著較「翠津」高，而硝酸鹽含量顯著較「翠津」低，相關含量分析結果對芥藍之食用營養具參考價值。本一代雜交新品系16-1232 於2018 年經行政院農業委員會農業試驗所通過自行命名為芥藍「鳳山1 號」，是一代雜交葉用型芥藍，具有早生、耐熱特性，適合於高溫高濕的環境生長；從撒播到採收僅需約40 d，定植到採收僅需約20 d；全株纖維少，口感細緻且略帶甜味，應更容易獲得消費者的青睞。 To breed a new Chinese kale hybrid with early mature and heat-tolerance, plant type, canopy, leaf shape, number of branching, growth period, and heat tolerance were evaluated in the Fengshan Tropical Horticulture Experiment Branch, Taiwan Agricultural Research Institute. Two heat-tolerant inbred lines, ‘Bao Xin Mei Kale’ and ‘Bai Hua Te Da Xin’, were selected as female and male parents, respectively. A new hybrid 16-1232 was selected after extensive comparison and field trials. The content of total sugar in 16-1232 was significantly higher than that of control cultivar ‘Chui Chun’ in either fresh or heated plants. Due to higher sugar content, 16-1232 tastes slightly sweeter. Acid analysis revealed that 16-1232 had higher l-malic acid and citric acid, and lower nitrate compared to the controls. The nutrition contents of edible Chinese kale provide an invaluable reference for breeders and consumers. The newly developed 16-1232 has been named Chinese kale ‘Fengshan No. 1’ after being approved by the council of Taiwan Agricultural Research Institute. F1 hybrid produces edible leaves with early maturity and shows heat-tolerance, which will be suitable for growing in high temperature and humid environments. ‘Fengshan No. 1’ can be harvested 40 d after sowing or 20 d after transplanting. Due to the characters of less fiber, delicate taste and slightly sweet flavor, ‘Fengshan No. 1’ would be widely accepted by consumers.
