Abstract : A study on the influence of sowing rates on the yield and grain quality of winter wheat varieties was conducted in the climatic zone of Akhaltsikhe. Among the tested varieties of winter soft wheat—Akhaltsikhe Red Doli, Tbilisuri 15, and Sauli 9—the latter two stood out for their yield and grain quality. Under Akhaltsikhe conditions, their yield exceeded the control (Akhaltsikhe Red Doli) by 0.4 t/ha. At the same time, the protein content in the grain of Tbilisuri 15 and Sauli 9 winter wheat exceeded the control by an average of 0.2–1.1%, while the gluten content was 0.6–3.9% higher. For all winter wheat varieties in the study region, the 1000-grain weight and test weight (hectoliter weight) were best when sowing 5 million viable seeds per hectare. According to the research results, the optimal sowing rate for achieving high yields of high-quality grain is 4–5.0 million viable seeds per hectare.
