Abstract: Using the 208 RAPD markers and association mapping in 18 portion materials of Spiraea L.,by scanning their genome in this study. We analyzed their population structure and performed the association analysis between RAPD markers and 28 ornamental traits. The results showed that:Eighteen portion materials of Spiraea L. were composed of 6 subpopulations;There were 23 RAPD markers associated with 16 ornamental traits in the population,there were 5 RAPD markers associated with 2 or more traits;Seven super association markers(s5-2,s152-6,s1216-1) of the ornamental traits and their carried species were detected. These markers associated with flower period(s5-2 total 2),colored- leaf period(s1049-9 total 2),flowering biological habit(s22-1 total 7),flower color(s103-9 total 3)and petal shape(s22-7)of ornamental traits. The carried species were S. bumalda‘Gold Mound’,S. bumalda‘Gold Flame’,S.thunbergii Blume,S. japonica Linn.and S. chamedryfolia L.

Key words: Spiraea L., ornamental trait, RAPD marker, association mapping
