Transferability of microsatellite markers of Capsicum annuum L. to C. frutescens L. and C. chinense Jacq.

In order to support further genetic, diversity, and phy- logeny studies of Capsicum species, the transferability of a Capsicum annuum L. simple sequence repeat (SSR) microsatellite set was ana- lyzed for C. frutescens L. ("malagueta" and "tabasco" peppers) and C. chinense Jacq. (smell peppers, among other types). A total of 185 SSR primers were evaluated in 12 accessions from 115 C. frutescens L. and 480 C. chinense Jacq, representing different types within each species. Transferability to C. frutescens L. and C. chinense Jacq. occurred for 116 primers (62.7%). Nineteen (16.37%) were polymorphic in C. frute- scens L. and 36 (31.03%) in C. chinense Jacq., 17 of which were coin- cident and could be used to analyze samples obtained for the 2 species. Among these primers, CA49 showed a different amplitude range of al- leles between the 2 species (130-132 base pairs for C. frutescens L. and
