Comparative trials with durum‐wheat landraces and cultivars in different ecological environments in the mediterranean region Durum‐wheat landraces (local varieties) and cultivars (released varieties) were examined for grain yield and some qualitative traits in three environments in 1985 and 1986. The purpose of this research was the preservation of the local genetic material and its use in durum‐wheat breeding programmes in mediterranean countries. It was confirmed that, during the graining period (heading to yellow ripeness), the landraces were more resistant to drought and high temperatures than the cultivars. A short graining period led to a sharp rise in the percentage of protein. On the other hand, the protein content decreased when the grain yield increased. Contrary to the cultivars, the vitrousness of some landraces was not negatively influenced by high soil moisture during the graining period. These landraces combined high grain yield with a high percentage of vitrous kernels and can be considered as valuable gene material for breeding purposes.
