Abstract

Genetic linkage maps are deployed to locate quantitative trait loci (QTL) of traits of interest and speed up breeding programs. In this study, we used two Vicia faba L. backcross families (BCFams). Genetic linkage maps were constructed with 193 and 288 polymorphic amplified fragment length polymorphism (AFLP) markers using 131 and 132 individuals for BCFam1 and BCFam2, respectively. The BCFam1 linkage map consisted of 18 linkage groups (LGs) encompassing1134.7 cM, with a mean inter-marker distance of 11.94 cM. The BCFam.2 linkage map consisted of 19 LGs encompassing1235 cM with a mean inter-marker distance of 9.29 cM. A set of 13 AFLP markers was homologous among maps of BCFam1 and BCFam2 as well as faba bean consensus map. These linkage maps will be beneficial for genetic analyses and diversity studies as well as for comparative mapping of faba bean and related species.
