The collection of 33 winter spelt wheat cultivars Triticum spelta was submitted to the electrophoretic analysis in the polyacrylamide gel and the results were evaluated on the qualitative and quantitative biochemical level. Following estimation of high-molecular-weight glutenin subunits composition detected that 27 cultivars have been uniform in this parameter and six cultivars have been non-uniform. The most often represented biotype appeared was the D biotype with 1, 6 + 8, 2 + 12 high-molecular-weight glutenin subunits composition and 6 Glu-score value. This one was determined by 19 cultivars (57.6 %). The most non-homogeneous cultivar of Swiss origin H 92-20 was proved, by which five unequal biotypes with the majoritarian representation of D biotype, the most repeatedly occurred biotype of the whole examined spelt wheat cultivars collection, was detected in the 24 singular grains. By all other mentioned non-uniform cultivars two or three biotypes were appointed.
