AB  - 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 
      ('Cayu-UNRC', 'Cume-UNRC', 'Genu-UNRC', 'Ninca-UNRC', 'Quine-UNRC', and 
      'Tizne-UNRC'), released by the Universidad Nacional de Rio Cuarto (UNRC), 
      Cordoba, Argentina. The cultivars were obtained from the International Center for 
      the Improvement of Maize and Wheat (CIMMYT) and improved for fresh forage, 
      haymaking, and feed grain at UNRC. The distribution and organization of highly 
      repetitive DNA sequences of Secale cereale (pSc74, pSc200, pSc250, and pSc119.2) 
      using FISH analyses revealed a specific localization of the signals for several 
      rye chromosomes, which allowed us to distinguish the cultivars. Cluster analysis 
      showed a great cytogenetic similarity among the rye cultivars used to originate 
      these hybrids. The knowledge of the variability among triticale cultivars is 
      necessary to propose future crosses in breeding programs. This study will also be 
      valuable to identify commercial seeds and to analyze the possible association 
      between agronomic characters and the presence of certain rye chromosomes or 
      specific regions in these chromosomes.
