FIGURE 5.

The results of a mcGISH analysis of the genetic composition of somatic hybrids (SH), back-cross progenies (BC₁ and BC₂) – examples; green labels S. tuberosum, red labels S. bulbocastanum GLKS 33741 (blb41) chromosomes: (A) SH 83/9 - total 72 chromosomes, in red S. bulbocastanum = 24; (B) BC₁ 83/9/3 - total chromosomes 54, 10 red from blb41 (C) Detailed magnifications of the introgressions from blb41 (red) into potato chromosomes (green) in BC₁ 83/9/3, SH 95/1 and BC₂ 95/1/4/59 (as indicated by red arrows); (D) SH 95/1 – total 64 chromosomes with 24 blb41 chromosomes in red; (E) BC₂ 95/1/4/59 (total 48 chromosomes, 4 red from blb41 and recombinations – with red and green); Yellow regions denote the complementarity of the respective sequences; bar = 5 μm.
