Fig. 2. Amplification fragment length polymorphism (AFLP) marker map for chromosome 3, established by the use of software JoinMap (Stam, 1993), for Apex x Prisma recombinant inbred line population of barley (redrawn from Yin et al., 1999b). The AFLP markers are labeled E45M55-408, E44M58-196, etc., and their map positions are counted in genetic map units, cM (1 cM corresponds to 1% recombination per meiosis), from the top terminal marker. The position of the denso dwarfing gene is highlighted.
