摘　　要：运用灰色系统理论中关联度分析法,对萝卜(Raphanus sativus L.)杂交组合的株高、展开度、叶片数、叶重、叶长、叶宽、根长、根粗和外露长9个相关农艺性状与肉质根产量进行了分析。结果表明,萝卜杂交组合单根重与其相关性状的关联度为:株高0.7533、展开度0.7057、叶片数0.7251、叶重0.6885、叶长0.6888、根长0.7652、根粗0.6791、外露长0.7626和叶宽0.6973,关联序和灰色权重依次为:根长>外露长>株高>叶片数>展开度>叶宽>叶长>叶重>根粗。By means of grey system theory, the association analysis was made between the root weight and 9 relevant agronomic characters （plant height, angular divergence, leaf number, leaf weight, leaf length, leaf width, rootlength, root diameter and outside rootlength） in radish crosses. The results showed that the association grade between the fleshy root yield and main characters was as follows： plant height 0.7360, angular divergence 0.7041, leaf number 0.7259, leaf weight 0.6875, leaf length 0.6901, root length 0.7665, root diameter 0.6806, outside root length 0.7665 and leaf width 0.6978. The order of association grade and the gray weight of main characters to yield was： root length〉outside root length〉 plant height〉 leaf number 〉 angular divergence 〉 leaf width 〉 leaf length 〉 leaf weight 〉root diameter .
