摘　　要：为了客观准确地评价4个不同主栽甘蓝品种在银川地区的适应性,比较了供试品种的株高、冠幅、球重等生物学性状,并运用主成分分析方法对主要农艺性状进行了分析。结果表明,供试品种的综合性状在银川地区的适应性均较好,中心柱高与全株质量之间均存在正相关关系,叶球紧实度与全株质量之间存在非常紧密的负相关关系。叶球纵径与单球质量之间呈现显著性(P≤0.05),相关系数为0.976,叶球纵径也是影响单球质量的关键因素。主成分PC1和PC2对应特征值均大于5,且累计贡献率分别为60.915%和96.497%,基本解释变量中的大部分信息。根据各品种的综合得分,秦甘50的综合性状表现最为突出,综合评价分值为0.868,其为供试品种中最适宜在银川地区种植的甘蓝品种,适合银川地区推广种植。In order to objectively and accurately evaluate the adaptability of four main varieties of cabbage in Yinchuan area,the biological characters such as plant height,crown width and ball weight were compared,and the main agronomic characters were analyzed by principal component analysis.The results showed that the comprehensive traits of the tested materials had good adaptability in Yinchuan area,there was a positive correlation between center column height and whole plant mass,and there was a very close negative correlation between leaf ball compaction and whole plant mass.The longitudinal diameter of leaf ball showed significant correlation with single ball mass(P≤0.05),and the correlation coefficient was 0.976.The longitudinal diameter of leaf ball was also the key factor affecting single ball mass.The corresponding characteristic values of principal component PC1 and PC2 were both greater than 5,and the cumulative contribution rates were 60.915%and 96.497%,respectively.Most of the information in the basic explanatory variables,according to the comprehensive scores of various varieties,the comprehensive traits of Qingan 50 were the most prominent,and the comprehensive evaluation score was 0.868,which was the most suitable for planting in Yinchuan area among the tested materials Varieties,suitable for the promotion of planting in this area.
