摘    要:为了丰富该地区品种类型,创造更高的经济价值,提高冀西北蔬菜产业整体效益。本研究在冀西北高寒环境条件下,对来自国内外的35个结球甘蓝品种的41个重要农艺性状进行观测鉴定。发现质量性状存在明显变异,数量性状的变异系数分布在8.00%~37.09%之间。主成分分析将19个数量性状归为4个主成分,即单株产量因子、外叶因子、叶柄因子、叶球因子,它们对综合表现的累计贡献率达到84.31%。表型聚类分析将35个品种分为3组,且少数品种相似性极高。通过综合评分,筛选出15个综合性状表现突出、适合当地栽培和不同用途的优良品种。研究结果为冀西北特殊条件下的甘蓝产业发展和育种工作的开展打下了良好的基础。

关 键 词:结球甘蓝  农艺性状  主成分分析  聚类分析  主成分因子得分

Abstract:To enrich vegetable cultivar resource, increase economic value and improve the overall efficiency of vegetable industry in northwest Hebei Province, we observed and identified 41 important agronomic traits of 35 cabbage cultivars under the alpine environmental condition. It is found that there is a significant variation in quality traits, and the coefficient of variation (CV) of quantitative traits ranges from 8.00% to 37.09%. Based on principal components analysis, 19 quantitative traits are classified into 4 factors: yield factors, outer leaf factors, petiole factors, and leafy head factors, and their cumulative contribution rate to the comprehensive performance reaches 84.31%. By phenotype cluster analysis, thirty-five cultivars are divided into 3 characteristics groups, and some cultivars are highly similar. According to comprehensive scoring, 15 excellent cultivars which are suitable for local cultivation and different uses are screened out. The result could lay a foundation for the development of cabbage industry and cabbage breeding under the special conditions in northwest Hebei Province.
Keywords:heading cabbage  agronomic traits  principle component analysis  clustering analysis  comprehensive scoring
