以22份紫红色胡萝卜地方资源为试材,对其抽薹率、根长和根型等14个农艺性状进行主成分分析。结果表明:主要农艺性状可归纳为根肩型、根型、根心柱色、抽薹率、根肩绿色程度、叶面茸毛、叶长和根粗等8个主成分,累计贡献率为88.14%。该结果可为紫红色胡萝卜育种合理选配亲本提供参考依据。 22 local resources of magenta carrot were used as experimental materials to make principal component analysis of 14 agronomic traits such as bolting rate, root length and root type. The results showed that the main agronomic traits could be summarized as eight main components of root and shoulder type, root type, root column color, bolting rate, green degree of root and shoulder, leaf hair, leaf length and root thickness, the cumulative contribution rate was 88.14% . The result may provide a reference basis for magenta carrot breeding reasonable matching parents.
