Abstract. In recent years, there has been an increasing of interest among farmers for cultivation of durum wheat varieties in Northern Kazakhstan. Due to the growth of export sales of durum wheat grain to countries of the Mediterranean basin. To increase gross grain harvests, new high-yielding varieties of durum wheat with grain quality that meets the requirements of modern grain processing production are needed. The purpose of the research is to evaluate the yield and grain quality of varieties and lines to identify promising genotypes for breeding of durum wheat in conditions of Northern Kazakhstan. Methods. In the competitive variety trial of scientific and production center of grain farming released varieties and promising lines of durum wheat were studied in 2021–2023 with usage field and laboratory research methods. Scientific novelty. New scientific data were obtained on the formation of yield and technological traits of grain by released varieties and promising lines of spring durum wheat under conditions of Northern Kazakhstan. The relationship between yield and economically valuable traits was studied to improve the efficiency of selection of breeding material for development of durum wheat varieties. According to research results, it is recommended to select breeding material based on number of grain per, grain weight per spike and plant, taking into account the risk of reducing the yield of semi-dwarf varieties. Lines 156-11-10, 270-16-13, and 28-16-15 with yield of 19.7–21.5 c/ha, characterized by gluten of the 1st quality group (51–66 units), protein and gluten content of 16.2–17.3 % and 33.3–36.9 % were selected. These lines are recommended for transfer to State Variety Trial and as initial material for development of high-yielding varieties of durum wheat with high grain quality.
