摘　　要：用不结球白菜杂交品种暑绿的112个双单倍体纯系构建了包含186个分子标记的遗传连锁图谱,利用复合区间作图法检测了叶片脯氨酸含量和可溶性蛋白含量两性状的数量性状基因座(QTL)。结果表明:叶片脯氨酸含量由位于第5连锁群上与分子标记C20相距7.2cM的QTL控制,其加性效应和贡献率分别为0.37%和8.32%;可溶性蛋白含量由位于第3连锁群上与分子标记AE153相距0.8cM的QTL控制,其加性效应和贡献率分别为0.004%和8.12%。In this study,an attempt was made to detect quantitative trait locus(QTL)for the leaf proline content and soluble protein content in a double haploid(DH)population derived from F1 hybrid variety Shulü by using composite interval mapping approach,based on a genetic linkage map with 186 molecular markers.The result showed that one QTL was detected for each of the two traits above.For leaf proline content,the QTL,with additive effect of 0.37% and the proportion of the total phenotypic variation explained of 8....
