Differentiation of triticale cultivars through FISH karyotyping of their rye chromosomes
The aim of this work was to cytogenetically characterize triticale cultivars through fluorescence in situ hybridization (FISH) analysis of their rye chromosomes. In the present work, we studied six cultivars of triticale ('Cayú-UNRC', 'Cumé-UNRC', 'Genú-UNRC', 'Ñin...
