Abstract
the consumer's interest in natural, unconventional and nutritional foods led to the development of new specialty foods based on grain blends. components of such foods are often so-called 'ancient wheats' or 'primitive wheats' which were never the subject of modern plant breeding programmes. einkorn (triticum monococcum), emmer (t. dicoccum) and khorasan (syn. oriental) wheat (t. turanicum) are such neglected and underutilized wheat species, which probably survived over the centuries in subsistence farming systems in europe, the near east and central asia. in the presented study, agronomic and qualitative traits of gene bank accessions of einkorn, emmer and khorasan wheat were evaluated under eastern austrian conditions. some einkorn and winter emmer accessions were found to be adapted to the prevalent climatic conditions, resulting in yields above 4000 and 5000 kg of hulled grains ha-1, respectively. some khorasan wheats, on the other hand, reached acceptable yields above 3000 kg grain ha-1 only if sown in autumn. however, winter hardiness of these types is only moderate which can result in total yield losses in case of harsh winters. considering technological quality (farinograph, extensograph, alveograph) all accessions turned out to be significantly inferior compared to common wheat. however, einkorn was confirmed as source for high yellow pigment content, and all three wheats contained significantly higher protein contents. hence, ancient wheats can represent sources for the production of specialty and/or health-promoting foods. however, they also represent a great challenge for the farmer and food technologist to find out the best suitable genetic material, and the best production and processing techniques
