| 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. |
