Fig. 5.

Chromosome associations at meiosis of pollen mother cells of BC₂F₂ (Ae. variabilis × S. cereale) × triticale ‘Lamberto’ hybrids. GISH images created using S^v-genome genomic DNA as a probe (green), with blocking genomic DNA of triticale. Chromosomes were counterstained with propidium iodide (a) or DAPI (b, c, d). a One 3S^v/3S^v bivalent in 3S^v/3B substitution line (2n = 42) at metaphase I of meiosis. b One 3S^v univalent in 3S^v addition line (2n = 43) at b metaphase I, c anaphase I and d telophase I of meiosis. Scale bars: 10 μm
