| 摘 要： | 为给中熟菜心的良种选育提供理论指导,研究采用灰色关联分析法，对10份中熟菜心品种的薹重与相关农艺性状进行分析。结果表明，中熟菜心的薹重与6个主要农艺性状的关联顺序为薹粗＞叶片数＞最大叶长＞最大叶宽＞叶柄长＞薹高，得出薹粗、叶片数和最大叶长是影响中熟菜心薹重的重要因素。因此，在中熟菜心高产品种的选育过程中，应优先考虑薹粗、叶片数、最大叶长等指标。

| Abstract: | In order to provide theoretical guidance for the selection and breeding of mid-mature Chinese flowering cabbage, grey correlation analysis was used to analyze stalk weight and related agronomic traits of 10 mid-mature Chinese flowering cabbage cultivars. The results showed that six major agronomic traits related to stalk weight were in following order: stalk diameter > leaf number > maximum leaf length >maximum leaf width > petiole length > stalk weight. It was concluded that the stalk diameter, leaf number and maximum leaf length are the important factors for stalk weight of mid-mature Chinese flowering cabbage. Therefore, the stalk diameter, leaf number and maximum leaf length for mid-mature Chinese flowering cabbage breeding should be prioritized. |
