Abstract

高溫是青花菜栽培過程中最常見的逆境因子，嚴重影響其產量和品質，且造成夏季蔬菜季之根本原因。本年度參試青花菜品系為169個篩選得到9個自交系，平均蕾球重在300公克，花球直徑在17公分以上，蕾球緊密、高溫結球性較佳；青花菜與白花芥藍雜交及回交之BC1F2世代中有4個雜交組合表現較優。 A total of 169 breeding lines were engaged in varietal observation, horticultural characteristics investigation, cross and purification. The results of their curd weight was heavier than 300g and curd diameter was larger than 17cm. The performance of curd formation and compact of curd during high temperature of these 9 lines was also well.
