Article 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.

This study aimed to identify QTL governing three traits of the resistance against the two planthoppers such as damage score (DS), nymphal survival (NS) and days to wilt (DW) using the 94 RIL population derived from the cross TN1/RP2068 utilizing 125 SSR and 1500 SNP markers. In case of the whitebacked planthopper (WBPH) five major and three minor QTL while for the brown planthopper (BPH) four major and seven minor QTL were identified to be associated with these three traits. Two major QTL, each on chromosomes 1 and 2, were responsible for DS and NS against WBPH accounted for 25% and 16% of the phenotypic variance (PVE).
