For mapping the Sec2 and Sec5 loci of rye which determine expression of 75K γ‐secalins, a partial genetic map of chromosome 2R spanning 64 cM was constructed. The map was developed using an F 2 population of 103 plants from a cross between two inbred lines. Both loci were mapped distally on the short arm of chromosome 2R and clearly tagged in relation to 12 restriction fragment length polymorphism (RFLP) markers. The Sec2 locus was localized between the Xiag57 and Xpsr109a loci in an 11 cM interval. The Sec5 locus co‐segregated to Xiag57 and was tightly linked to the Sec2 locus at a map distance of 0.5cM.
