aref2 2 The purpose of the work is to identify varieties of spring durum wheat on a complex of features, the most adapted to the conditions of Northern Kazakhstan, as well as the conjugacy of relations between the elements of the structure of yield and grain yield. The research material was an expanded set of promising and registered varieties of spring durum wheat: Damsinskaya yubileynaya, Damsinskaya 90, Sharifa, Khorosan, Solnechnaya 573, Altayka, Korona, Sid 88. The article presents the results of the study on the features of the interphase periods in varieties and the growing season as a whole, identifies economic and valuable features and elements of the structure of the yield of spring durum wheat in the steppe zone of Akmola region, as well as the technological evaluation of grain. Results. The vegetation period of spring durum wheat varieties averaged 76 days within the group, the longest vegetation period was observed in the standard variety Damsinskaya yubileynaya - 82 days, the shortest in the varieties Altayka and Khorosan - 71 days. The highest yield showed the kind of Sheriff - 2.3 t/ha compared to the standard Damsinskaya yubileynaya of 2.1 t/ha. For technological assessment grade Khorasan showed the best indicator of gluten to 38.4 % in comparison with the standard Damsinskaya yubileynaya - 36,2 %. The correlation between the growing season and yield of spring durum wheat varieties was revealed. Scientific novelty. In the steppe zone of Akmola region, a set of new promising varieties of spring durum wheat, characterized by good yield, high adaptive capacity, in comparison with zoned varieties, the technological assessment of grain is determined.
