灰色关联度多维综合评估在结球甘蓝品种评定中的应用

为了筛选出优质、高产、早熟、圆球形甘蓝新品种,采用灰色关联度多维分析法对10个早熟圆球型结球甘蓝品种的生育期、病情指数、球心指数、结球紧实度、中心柱长、单球质量、品质、商品产量等生物、经济性状进行综合评价。结果表明:应用灰色关联度多维综合评估结球甘蓝品种是完全可行的,能够较好兼顾品质、抗病性、商品性;中甘591、WG-1803、凯丽3个品种表现出抗病性好、高产、优质,应加强跟踪试验与观察,并适时进行示范推广。

Application of Multi-dimensional Comprehensive Evaluation of Grey Correlation Degree in Cultivar Evaluation of Cabbage (Brassica oleraceal L. var. capitata)

In order to screen out new round cabbage cultivars of high quality, high yield and early maturing, and biological and economic traits such as growth period, disease index, globule core index, globule compactness, length of central column, weight of single globule, quality, commodity yield of 10 early maturing round cabbage cultivars were evaluated by multi-dimensional analysis of grey correlation degree. The results showed that it was feasible to use the multi-dimensional comprehensive evaluation of grey correlation degree to evaluate the cultivar of cabbage, which could give good consideration to quality, disease resistance and commodity. ''Zhonggan 591'' ''WG-1803'' and ''Kaili'' showed good disease resistance, high yield and high quality, which should strengthen the follow-up test and observation, and carry out demonstration and promotion in time.
