摘　　要：利用灰色系统理论对双丰系列甜菜品种（系）有关甜菜15个农艺性状与产量、含糖率及产糖量的关联度进行了研究分析，结果表明，甜菜植物学株高农艺性状与甜菜产量、含糖及产糖量有较强关联性，关联系数分别为0．9697，排第3位、0．9766，排第7位、0．9701，排第3位，并提出增加甜菜“相对株高”植物学特征及测量方法，甜菜“相对株高”与“株高”进行比值，把传统的甜菜株型类型的定序型数据变为定距型数据即角度数字量化的观点。Grey correlation degree of fifteen agronomic traits with yield and sugar content and sugar yield in Sumfull sugar- beet varieties （lines） were studied using gray system theory. The result showed that there were a strong correlation between sugar - beet botany plant height and yield and sugar content as well as sugar yield, the correlation coefficients were respectively 0. 9697 and 0. 9766 and 0. 9701. Adding sugar beet ＇ relatively plant height＇ botany character and it＇ s measuring method were suggested, ＇ relatively plant height＇ and ＇ plant height＇ were matched, the opinion of changing ＇ scale ＇ data of traditional sugar - beet plant types to ＇ ordinal＇ data was proposed.

关 键 词：产量 含糖 株高 相对株高 株型 灰色关联度
