摘　　要：为筛选适宜在陕西太白高山冷凉地区种植的结球甘蓝品种,为该地区结球甘蓝品种的种植和推广提供科学依据,考察了15个结球甘蓝品种的植物学性状和产量水平,用逼近理想解的排序法(DTOPSIS法)对株幅、叶球纵径、叶球横径、中心柱高、单球质量等主要性状指标进行综合评价。试验结果表明,运用DTOPSIS法得出各理想解相对近似度(Ci)的最高值为0.7072、0.6739、0.6220,对应的品种分别为威风01、CR-绿崎、中甘596,其球形圆正、品质较好、结球紧实、产量高、商品性好、抗抽薹,适合在太白高山冷凉地区种植。To select out the cabbage cultivars suitable for cultivation in cold area of Taibai mountain in Shaanxi province,and to provide scientific basis for the promotion of cabbage in this area,taking 15 cabbage cultivars as materials,the botanical traits and yield levels were described.In addition,the dynamic technique for order preference by similarity to ideal solution(DTOPSIS)method was applied to comprehensively evaluate the major trait indicators including plant width,vertical diameter of head,transverse diameter of head,height of stem in head,and single head weight.According the test results of the DTOPSIS method,the highest values of Ci were 0.7072,0.6739 and 0.6220,and the corresponding cultivars were respectively Weifeng 01,CR-Lvqi and Zhonggan 596,which were round ball,good quality,compact bulb,high yield,high commodity and bolting resistance and suitable for planting in cold area of Taibai mountain.
