Abstract

Cytologic heterogeneity of triticale (Triticosecale Wittmack) has been well studied at both varietal and intravarietal Ievels.The aim of this work was to determine the degree of association between meiotic index (MI) or percentage of normal tetrades and post-tetrades index (PTI),namely percentage of abnormal microspores.Eight hexaploid triticale sublines fron two different varieties,Don Frank (DF) and Jenkins TA 203 (J) were evaluated during two ye ars.Statistical analysis showed a dissociation between indexes in J variety.PTI index would be most suitable for intravarietal selection based on cytological aspects.
