Abstract:: The principal components analysis on fourteen agronomic traits of 22 local purple carrots resources was carried out.The results showed that the main agronomic traits could be concluded to eight principal components including shoulder type，root type，colour of root center，bolting-rate，green degree of root shoulder,leaf surface fluff，leaf length，root diameter and the cumulative proportion achieved 88.14%.The results could provide reference for the reasonable parent selection for purple carrots breeding.
