摘要:

为明确不同品种不结球白菜的表型及品质差异,本研究选用15种不结球白菜种质开展比较试验,测定19个农艺性状和6个品质性状,并通过相关分析、主成分分析、聚类分析等方法,对不结球白菜进行综合评价,筛选高品质不结球白菜。结果表明,15种不结球白菜的株型、叶形、叶色等质量性状存在差异,叶柄长、单株重、叶片叶帮比、株高等数量性状及葡萄糖含量、果糖含量、粗蛋白含量、抗坏血酸含量4个品质性状的变异系数均大于30.00%。筛选出含糖量高的品种Q1、Q2和Q7,单株重大的品种Q5,抗坏血酸含量高的品种Q15。相关分析表明,不结球白菜的农艺性状间、农艺性状与品质性状间、不同品质性状间均存在一定的相关性。主成分分析筛选出叶柄厚、叶片叶帮比、果糖含量、粗纤维含量、抗坏血酸含量作为代表性关键指标,聚类分析将15种不结球白菜种质分为5类。以上结果为不结球白菜优质品种在育种和生产中的选择和利用提供参考依据。

Abstract:

To clarify the differences in phenotypic and quality traits among diverse non-heading Chinese cabbage varieties,this study conducted a comparative experiment using 15 non-heading Chinese cabbage varieties,19 agronomic traits and 6 quality traits were determined. Through correlation analysis,principal component analysis(PCA),cluster analysis,a comprehensive evaluation of non-heading Chinese cabbage was conducted to screen high-quality non-heading Chinese cabbage. The results showed that among the 15 varieties,distinct differences were observed in qualitative traits such as plant type,leaf shape,and leaf color. The coefficient of variation for quantitative traits such as petiole length,single plant weight,leaf to petiole ratio,plant height,as well as four quality traits including glucose content,fructose content,crude protein content,and ascorbic acid content,were all greater than 30.00%. Three varieties(Q1,Q2,Q7)were identified as high-sugar varieties,Q5 exhibited superior single plant weight,and Q15 was characterized by high ascorbic acid content. Correlation analysis showed that there were certain correlations between agronomic traits,agronomic traits and quality traits,and different quality traits of non-heading Chinese cabbage. Principal component analysis further identified representative key indicators:petiole thickness,leaf to petiole ratio,fructose content,crude fiber content,and ascorbic acid content. Cluster analysis ultimately classified the 15 varieties into five distinct groups. These findings provide valuable insights for the selection and utilization of high-quality non-heading Chinese cabbage varieties in breeding and production.

Key words: non-heading Chinese cabbage, agronomic traits, quality, comprehensive evaluation
