摘  要

  許涵鈞、謝明憲、林棟樑、王三太。 2009。 耐熱結球萵苣引種觀察比較試驗。臺南區農業改良場研究彙報55:36-43。

  結球萵苣為國際上大宗蔬菜,亦為台灣具外銷潛力的作物之一,由於目前所栽種的品種多缺乏耐熱性,產期集中在11月至翌年3月間。本研究於春作評估43個品系之植株生長表現,選拔出12個品系,此12個結球萵苣品種(系)於98年9-11月間分別在台南新化、雲林褒忠及麥寮等三地區試作,分別調查耐熱性及產量等園藝性狀。結果顯示「常利3號」及「合歡丹生10號」之產量及品質均表現優良且與目前主要種植品系‘3號’相似,適合推薦農民種植,可有效延長產期。

關鍵詞:結球萵苣、引種、耐熱性

Abstract

  Crisphead lettuce is one of the main vegetables in the world. This crop has the potential for export in Taiwan. The harvest season of crisphead lettuce is from November to March. Most varieties are lack of heat resistance. In this study the yield and heat tolerance of 12 lettuce varieties (lines) were investigated during September to November,2009 in Sinhua, Baojhong and Mailiao. The results showed that the weight and head size 'Chang Lee No. 3' and 'Acacia Dan No.10 ' were similar to ‘No.3’. This two cultivars could be introduced for early season.

Key words: Crisphead lettuce, Heat-resistance, Introduce
