The aim of this study was to explain the genetic variability of seven varieties of wheat (Triticum aestivum L.) and two varieties of triticale (hybrid wheat x rye) at unfertilized soil.The investigations included pigments content, leaf area, nitrogen content in the leaf, leaf and mesophyll thickness.Obtained results showed that there is a clear genetic variability in all tested components. Per study values for yield especially the prominent Lazarica genotype and both varieties hybrid species triticale – KG 20 and Knjaz,which also had the highest values for most parameters of productivity.Therefore, these genotypes of wheat can be recommend for organic production
