摘　　要：应用灰色关联度评判法,对15个耐热甘蓝亲本材料的7个农艺性状和5个品质指标进行综合评判。结果表明,12个性状的权重系数大小顺序为球高>外叶数>球径>株高>开展度>中心柱长>叶球质量>膳食纤维含量>蛋白质含量>抗坏血酸含量>碳水化合物含量>硝酸盐含量。综合评判结果表明,中甘17-4-6×可-H的综合评判值最大,为0.798,其次为107-H,可将二者作为重点的亲本材料,结合育种目标重点配制组合。7 agronomic traits and 5 quality indexes of 15 heat-resisting cabbage accessions were evaluated by using grey correlation analysis. The results showed that the order of gray relational weight of the 12 characters was as follows： head height〉numbers of outer leaves〉head diameter〉plant height〉plant width〉length of central column〉head mean weight〉dietary fiber content〉protein content〉ascorbic acid content〉carbohydrate content〉nitrate content. The comprehensive evaluation value of ZG 17-14-6xK-H and 107-H was 0.798 and 0.788 respective, and they were excellent parent materials in this test according to the breeding objective.
