Field trials were conducted in the years 2017&ndash:2019 at the Małopolska Plant Breeding in the Plant Breeding Stations in Polanowice, Nieznanice and Palikije. The trials were designed to determine the yield of some timothy genotypes in the context of chemical composition under different habitat conditions. The present evaluation of the strain quality shows a high potential for breeding. The analyzed genotypes produced high dry matter yields, which differed by as much as 53%. The experimental plots also differed in the crude protein content, which varied from 104.5 to 230.1 g kg&minus:1 d.m., depending on the crop and year of harvest. For crude fiber, these values ranged from 173.9 to 274.8 g kg&minus:1 d.m., depending on the crop and harvest year. The analysis of the mineral composition also revealed significant large variation.
