The article presents the results of a three-year field study (2023–2025) on the comparative assessment of ornamental quality, initial sod formation rate, and winter hardiness of turfgrass stands from perennial ryegrass (Lolium perenne L.) varieties of foreign breeding (Accent II, Goal Keeper II, Revenge GLX, Jacklin Seed, USA) and reproductive seeds of Russian production (MosAgroGroup LLC). The aim of the study was to assess the ornamental qualities and winter thinning of turfgrass from perennial ryegrass varieties of foreign and domestic breeding under the urbanized conditions of Moscow. The experiment was conducted at the the Edelstein Scientific and Practical Center of Horticulture and Vegetable Growing of the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy. Grass quality was assessed according to the method of A.A. Laptev using a 30-point scale, considering shoot density and projective cover area; winter hardiness was determined by the percentage of thinning in spring. In the first year of the study, the Accent II and Goal Keeper II varieties significantly surpassed the other variants in grass stand density (8700 shoots/m2), which was 61.11% higher than Revenge GLX and 7.82% higher than the variant with reproductive seeds. In the third year of the field experiment, the highest projective cover area was recorded for the variant with reproductive seeds (96%), which was 7.87% higher than Accent II (89%), 15.66% higher than Revenge GLX (83%), and 1.05% higher than Goal Keeper II (95%). Based on the comprehensive quality assessment, in the first year all variants except Revenge GLX (poor – 3 points) were rated as mediocre; in the second year, the variant with reproductive seeds and Goal Keeper II achieved excellent quality (25 points); in the third year, the variant with reproductive seeds and Goal Keeper II received the highest score (30 points). The thinning of L. perenne grass in the variant with reproductive seeds after winter periods was 29.49–30.25%, while in the cultivar variants it ranged from 41.98% to 53.26%.
