The aim of the research was to judge the effect of variety and cultivation locality on the content of starch and other indicators of technological quality and to pay an attention particularly to the possibilities of cultivation of starch-making wheat in marginal regions. The variety Contra excelled by the highest content of starch in grain in the evaluated set followed by the varieties Siria, Estica, Sarka, Samara and Versailles. These varieties were also marked by the satisfying content and good washing out of gluten, what is another factor that should be taken into account. An important fact with respect to the aims of research is suitability of all the above-mentioned varieties into the so-called marginal or submarginal regions, respectively (cereal-, potato- and forage-growing regions). Except suitable varieties in distribution of starch-making wheat production capacity of cultivation localities and hence yield capacities of wheat and starch production of starch per 1 hectare should be taken into account. This is economically acceptable in regions with a production potential of soil above 55-60 points in cereal- and potato-growing region. Good yields can be obtained by the proposed varieties in these conditions.
