摘要： 为揭示不结球白菜单株产量与主要农艺性状间的关系，利用灰色关联度分析法，对18个不结球白菜品系的单株产量和8个主要农艺性状间的关联度进行分析。结果表明，不结球白菜各农艺性状与单株产量性状间的关联度排序为株幅＞最大叶叶宽＞最大叶叶柄宽＞最大叶叶柄厚＞叶片数＞最大叶叶长＞株高＞最大叶叶柄长。株幅、最大叶叶宽、最大叶叶柄宽对不结球白菜单株产量影响最大。在不结球白菜育种过程中，注重株幅、最大叶叶宽、最大叶叶柄宽性状的选择，同时兼顾其他性状的选择，可以获得单株产量较高的不结球白菜新品种。

Abstract: To reveal the relationship between yield per plant and main agronomic traits of non-heading Chinese cabbage, the grey relation analysis method was adopted to analyze the correlation between yield per plant and eight main agronomic traits of 18 non-heading Chinese cabbage strains. The results indicated that the 8 main agronomic traits were related to yield per plant in the order as follows: plant width＞ maximum leaf width＞ maximum leaf petiole width＞ maximum leaf petiole thickness＞ number of leaves＞ maximum leaf length＞ plant height＞ maximum leaf petiole length. Plant width, maximum leaf width and maximum leaf petiole width had the maximum influence on yield per plant of non-heading Chinese cabbage. To obtain new non-heading Chinese cabbage varieties with preferable yield in breeding practice, the selection of plant width, maximum leaf width and maximum leaf petiole width should be emphasized, while the selection of other traits should be taken into account.
