Two selected collections of spring wheat were investigated in order to determine the technological quality of grain, dry matter and crude protein yields per 1 ha, 1000-grain weight and plant height. Technological analyses involved crude protein content, microsedimentation value of groats, wet gluten content in flour, gluten swelling and extensibility. In the three-year trial, the crude protein content was highest in the Tr. durum cultivar Arcour from France (16.5 g per 100 g grain dry matter), followed by the Czechoslovak cultivar Maja (15.6 g) French cultivars Ventura (15.3 g) and Lobo (15.2 g). The Ventura cultivar had the highest microsedimentation value (8.1 ml). Grain and crude protein yields per 1 ha were highest in the Czechoslovak cultivars Maja (5.3 t and 837.7 kg), Saxana (5.3 t and 763.7 kg), Sandra (5.3 t and 760.9 kg), Jara (5.1 t and 759.3 kg) and in the Polish cultivar Eta (5.1 t and 746.3 kg). In the two-year trial, the American cultivar Treasure had the best quality, as well as good yields. In the three-year trial the 1000-grain weight was highest in the advanced line Pato (45.2 g) and in the Sigma cultivar from Poland (43.7 g). In the two-year trial, the highest 1000-grain weight was determined in the Messa pia cultivar of Tr. durum from Italy (46.0 g). In both trials, the values were influenced by individual years.
