Abstract

The translocation between the short arm of chromosome 1R of rye and the long arm of chromosome 1A, 1B or 1D of wheat represents practically the most common introduced foreign genes into the genome of hexaploid wheat. 1RS chromosome arm represents a source of different useful genes, associated with increased disease resistance, improved adaptability, stress tolerance, and increased stability and level of yield. On the other hand, translocation is associated with poor technological quality of wheat as a result of the presence of secalin and reduced number of gluten loci. The aim of this study was to determine the prevalence of 1RS translocation among some Croatian winter wheat varieties using molecular markers. The study included 40 varieties of which 23 Croatian. Four pairs of primers: RIS, SCM9, RYE-NOR and PAW161 were used for determination of translocation. The presence of translocation was determined in 12 of 40 (30%) varieties, while among the Croatian wheat varieties translocation had 8 of 23 (34.78%) varieties (Zlatna Dolina, Barbara, Nova Žitarka, Marija, Prima, Kuna, Koleda and Dea).
