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). Meiotic irregularity counts were repeated after 5 years; during this period the material was sown consecutively. The cultivars analyzed were: Cachirul...

Meiotic irregularity counts were repeated after 5 years; during this period the material was sown consecutively.

Se concluye que para analizar estabilidad meiótica no es necesario determinar frecuencias de laggards. De los 5 cultivares estudiados, Triticale 0205 es el único citológicamente estable.
