The first genetic linkage map of <Emphasis Type="Italic">Primulina eburnea</Emphasis> (Gesneriaceae) based on EST-derived SNP markers

Primulina eburnea is a promising candidate for domestication and floriculture, since it is easy to culture and has beautiful flowers. An F ₂ population of 189 individuals was established for the construction of first-generation linkage maps based on expressed sequence tags-derived single-nucleotide polymorphism markers using the massARRAY genotyping platform. Of the 232 screened markers, 215 were assigned to 18 LG according to the haploid number of chromosomes in the species. The linkage map spanned a total of 3774.7 cM with an average distance of 17.6 cM between adjacent markers. This linkage map provides a framework for identification of important genes in breeding programmes.
