Abstract

Abstract Fourteen microsatellite primer pairs were developed from a cDNA library of heat‐treated seedlings of Fragaria vesca cv. yellow wonder. Transferability to 13 species of Fragaria ranged from 71% in diploid species F. gracilis Losinsk., F. iinumae Makino, F. nilgerrensis Schltdl. ex J. Gay and F. nipponica Makino, to 100% in octoploid domestic strawberry and its progenitors. Polymorphism was high in polyploid Fragaria species. However, polymorphism and heterozygosity of eight EST‐SSRs (expressed sequence tag–simple sequence repeats) was low in 14 F. vesca genotypes.
