Yield and agronomic traits of Khorasan wheat (Triticum turanicum Jakubz.)
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' which were never the subject of modern plant breeding programmes. Khorasan or Oriental wheat (Triticum turanicum) is a neglected and underutilised tetraploid wheat species, which probably survived over the centuries in subsistence farming systems in the Near East and Central Asia. In the present study the agronomic potential of Khorasan wheat was evaluated under eastern Austrian conditions. Fourteen accessions of Khorasan wheat were investigated together with check durum wheat cultivars over a period of 4 years in the Marchfeld region, north-east of Vienna. The crops were sown both in autumn and spring. The investigated material was inferior to modern durum wheats in most agronomic traits. No accession was found to tolerate soil temperatures below -5 °C. Tolerance to drought and fungal diseases was limited and/or modest, and grain yields were significantly lower. While the best performing turanicum accessions yielded in average 385.8 and 233.8 g m-2 for autumn and spring sowing, respectively, the check winter durum yielded 466.5 g m-2 and the check spring durums between 351.5 and 391.8 g m-2. Several characteristic and interesting features were obsered which permit successful marketing of pure Khorasan grain or as a component in grain blen
