对国内外30份白菜型春油菜品种(Brassica campestris L)的一些质量性状进行了简单评比归类;对几个生理和数量性状用平均数、标准差和变异系数指标进行了单一性状变异度分析,揭示了在这些性状上品种的生态型特性。并综合生理、数量和质量性状31项,用模糊聚类的分析方法将其生态型聚为四类。结果表明,聚类与品种地理分布、生育时期,株高和单株产量密切相关。
Some quality traits of 30 Brassica campestris L. cultivars at home and abroad were classified by simple classification. The average, standard deviation and coefficient of variation of several physiological and quantitative traits were analyzed by single trait variability , Reveals the ecological characteristics of varieties in these traits. In addition, 31 items of physiological, quantitative and qualitative traits were synthesized, and their ecotypes were clustered into four categories by means of fuzzy cluster analysis. The results showed that the clustering was closely related to the geographical distribution of cultivars, growth period, plant height and yield per plant.
