Genomic in situ hybridization (GISH) on mitotic chromosomes of (Ae. variabilis × S. cereale) × triticale ‘Lamberto’ hybrids. On the GISH images, the R-genome is visualized in blue, the A-genome and the B-genome in grey; the U^v-genome is visualized in red and the S^v-genome in green. a F₁ hybrid with 14 chromosomes of Ae. variabilis (7 chromosomes of U^v-genome and 7 chromosomes of S^v-genome). b BC₁F₁ hybrid with 7 chromosomes of Ae. variabilis (4 chromosomes of U^v-genome and 3 chromosomes of S^v-genome). c BC₁F₁ hybrid with 2 chromosomes from U^v-genome of Ae. variabilis and 21 chromosomes of triticale with introgression of S^v-genome chromatin. d BC₂F₁ hybrid with 3 chromosomes from of S^v-genome of Ae. variabilis.
