Abstract

The new SSR markers of rose related fragrance were developed based on the SSH cDNA libraries of rose floral scent mutant. In this study, 10 EST-SSRs (2.6%) from 391 ESTs in the libraries were identified. Six EST-SSRs primers were designed to sequence flanking SSRs. The primer pairs designed were screened on the wild-type Jinyindao, which has flowers full of pleasant scent, and the mutant-type Wangriqinghuai without perceivable floral scent. Five primer pairs were amplified effectively in Jinyindao and Wangriqinghuai, and 3 were polymorphic between Jinyindao and Wangriqinghuai. Eighteen rose cultivars including fragrant roses and nonfragrant roses were identified by the five prime pairs. These results proved that EST-SSR markers are effective markers to identify the polymorphism of the rose.
