Figure 2. Distribution of simple sequence repeat (SSR) primers selected from wheat. Distances between markers do not reflect the exact map positions. Primer pairs in bold letters produced positive polymerase chain reaction (PCR) products in oat lines. Numbers at the top represent the specific chromosomes. A, B, and D after each number designate the different subgenomes of the chromosomes. Marker Barc59 is indicated on both chromosomes 5B and 2D.
