Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Aims. Development of triticale secondary recombinant gene pool for use in breeding for semidwarfness and resistance
to pre-harvest sprouting. Methods. Chromosome-engineering technologies in combination with molecular-cytogenetic
and DNA labelling of genotypes. Results. Hybridization of substituted 6x-triticale forms with modern crop cultivars
was carried out. Eight stable recombinant lines with different D(A)- and D(B)-chromosome sunstitutions were selected
out of hybrid populations F4
by chromosome differential Giemsa staining (C-banding). Allelic composition of genes
affecting formation of semidwarfness (Rht-B1, Rht8) and resistance to pre-harvest sprouting (Vp-1B) was investigated in
the selected forms. Conclusions. A high frequency of D-genome chromosome inclusion in karyotype of triticale cultivars
and dependence of the effectiveness of the introgression process on the genotypic environment of the developed hybrid
form were revealed. Recombinant triticale lines, promising for breeding, were selected according to the data of moleculargenetic analysis.
Keywords: triticale, chromosome-substitution lines, semidwarfness, resistance to pre-harvest sprouting, molecular
markers.
