El Catálogo Colectivo reúne los registros del material que posee cada una de las
bibliotecas de la Universidad Nacional de Córdoba, pudiendo encontrarse colecciones
especializadas y actualizadas en todas las áreas del conocimiento; lo que permite una
amplia visibilidad y garantiza el acceso al patrimonio documental de la Universidad.
Se encuentra disponible para toda la comunidad académica: estudiantes, docentes,
egresados e investigadores.
Si formas parte de la comunidad de la UNC también podés solicitar préstamos de material,
a cualquier biblioteca universitaria, utilizando el servicio de préstamo interbibliotecario,
independientemente de la facultad a la que pertenezcas, la carrera que curses o la cátedra
que dictes.
Cytogenetics of Triticales. Meiotic Abeirations in Hexaploid Triticales
Cytological stability was studied in hexaploid triticales through observations of meiotic aberrations (univalents in Ml and micro nuclei in Tetrads).

Cytological stability was studied in hexaploid triticales through observations of meiotic aberrations (univalents in Ml and micro nuclei in Tetrads). Meiotic irregularity counts were repeated after 5 years; during this period the material was sown consecutively. The cultivars analyzed were: Cachirulo, 6 I'A 204; Triticale 0205; Triticale 0204 and Rosner. The observations were made in CMP and the statistical analysis was carried out using the Differences of Proportions Test. It is concluded that to analyze meiotic stability it is not necessary to determine laggard frequencies. Of the 5 cultivars studied, Triticale 0205 is the only one cytologically stable.
