摘要：

为筛选出适宜在成都平原根肿病高发区栽培的青梗菜新品种，本研究以87个青梗菜品种为供试材料，开展品种比较试验，调查各品种的农艺性状、根肿病抗性和产量性状，采用主成分分析结合隶属函数法进行品种综合评价。结果表明：通过对14个关键指标的主成分分析，提取到4个主成分综合指标，其累计贡献率达82.874%，充分反映了供试品种的整体遗传信息。其中，综合指标1主要与单株重、菜头粗、叶柄宽、腰粗、叶柄厚、产量等性状相关性较大，与综合指标2相关性较大的性状有叶长、叶柄长、株高、株幅，与综合指标3密切相关的性状是根肿病病株率和根肿病病情指数，与综合指标4相关性较大的性状是叶宽、莲座叶数。基于各品种不同性状的标准化数据与特征向量，计算出4个主成分的综合指标值，进而求得各综合指标的隶属函数值、权重及各品种的综合评价D值。87个品种的D值介于0.307~0.833之间，D值越大表明品种综合表现越好。综上，综合排名前三的品种依次为：‘夏赏味2号’、‘夏威青梗菜’和‘春赏味’，较适合在成都平原的根肿病病区种植，其中‘夏赏味2号’和‘夏威青梗菜’对根肿病免疫；‘紫冠骄子’综合排名末位。

Abstract:

To screen out new pakchoi varieties suitable for cultivation in clubroot affected areas of Chengdu Plain，we conducted a comparative trial by using 87 pakchoi varieties, investigated agronomic traits, clubroot resistance, and yield-related characteristics. A comprehensive evaluation was performed by using principal component analysis (PCA) combined with the membership function method. The results showed that PCA of 14 indicators extracted 4 principal components (PCs), with a cumulative contribution rate of 82.874%. PC1 was primarily correlated with plant weight, head diameter, petiole width, waist diameter, petiole thickness, and yield. PC2 showed strong correlations with leaf length, petiole length, plant height, and plant width. PC3 was closely associated with the incidence of clubroot and clubroot disease index. PC4 was mainly correlated with leaf width and rosette leaf number. Based on standardized data of various traits and the corresponding eigenvectors, the comprehensive indicator values for 4 PCs were calculated. Subsequently, the membership function value and weight of each PC and comprehensive evaluation D value of each variety were derived. The D values of the 87 varieties ranged from 0.307 to 0.833, with higher D values indicating better overall performance. In conclusion, the top 3 varieties in the comprehensive ranking were ‘Xia Shang Wei No. 2’, ‘Xia Wei Pakchoi’, and ‘Chun Shang Wei’, all of which were suitable for cultivation in clubroot-affected areas of Chengdu Plain. Notably, ‘Xia Shang Wei No. 2’ and ‘Xia Wei Pakchoi’ exhibited immunity to clubroot, and ‘Zi Guan Jiao Zi’ ranked the last in the overall ranking.
