Emmer wheat, Triticum dicoccum SCHRANK (SCHUEBL), is an old species of cereal which has been traditionally grown in arid areas. The renewed interest in this variety has its origin in favourable quality parameters of emmer wheat grain and a beneficial effect on human organism. This article deals with a study of quality parameters and storage protein composition of 6 varieties of emmer wheat (which have been chosen from the collection of gene bank at the Research institute of Crop Production in Prague-Ruzyně and in České Budějovice). High crude protein content in grain was proved during the trials. Nevertheless, such a characteristic is not suitable for the classical bakery processing (production of leavened products). The analysed genotypes contain more than 10% of high molecular weight glutenins (HMW glutenins), approximately 70% of low molecular weight glutenins + gliadins (LMW glutenins + gliadins), and almost 20% of residual albumins and globulins. Thanks to high share of albumins and globulins, emmer wheat grain is very valuable raw material for the production of healthy diet. The level of stability of storage proteins composition destines the suitability of emmer wheat for organic and low input farming in Less Favoured Areas.

Cereals, the yield of which is strongly influenced by a well-selected variety, belong to the most important crops of organic farming, grown on arable land. At first a questionnaire study was executed among organic farmers in 2006 to gain information concerning the choice of variety, structure of growing, and yield of cereals in the Czech Republic. The actual cultivars of wheat are bred to be suitable for intensive farming. Therefore, not all the actual cultivars are suitable for organic farming. The methodology of tests of the suitability of cultivars for organic farming was elaborated and tested in 2006. Particular morphological, biological and agricultural features were evaluated. Selected Austrian cultivars, which were recommended for in organic farming system and breeded strains were tested. It is difficult to achieve sufficient protein content in grain in the organic farming system. The fact that the protein content in landraces of wheat is higher than the protein content in modern breeded varieties was confirmed. These varieties adapted to local conditions very well. Most of the evaluated varieties contain more crude protein in grain than modern varieties and may achieve a very good-quality production, but on a lower yield level the same as varieties of emmer.
