FIGURE 2

The introgression of a small fragment of Ha. villosa chromosome 6V into a distal site of wheat chromosome arm 6AS. Two independent introgression lines were inter-crossed: one carries the terminal portion of chromosome arm 6VS and the other a proximal segment, while both carry Pm21, which lies in the short common interstitial segment. As a result of a homologous recombination event in the F1 hybrid, segregants are generated which carry only the short interstitial segment [Figure redrawn from Lukaszewski and Cowger (2017)].
