Abstract (English):
From the genus bentgrass (Agrostis L.) red top (A. gigantea Roth.) is the most adaptive species. Red top varieties Chara and Alba have been created and registered in the State Register of Breeding Achievements Approved for Use in the territory of the Russian Federation in the Federal Scientific Center "VIK named after V.R. Williams". The varieties are characterized by high adaptive potential and unpretentiousness. They are characterized by competitiveness when cultivated in poly-species grass mixtures. In the conditions of the Central region of Russia, the Chara variety forms high yields of green mass in the mode of triple mowing, up to 47.2 t/ha, dry weight 12.1 t/ha, which is 25.4 and 38.3% higher than the standard. The yield of seeds of the Chara variety from grass stands of the first year of use is 400 kg/ha, which is 36.8% higher than the standard. The Alba variety is characterized by increased drought resistance. Designed for lawn and pasture use. In the conditions of the Central Chernozem region, the yield of green mass is 27.3–34.5 t/ha, seeds — depending on the year of use of the herbage, 412–194 kg/ha. When lawn varieties are used, the density of shoots in the herbage of the second year of life can reach 76.0 thousand pcs/m2. In conditions of sufficient moisture, with the observance of lawn care technology, a high density of shoots can be maintained for 6 years. The varieties are resistant to disease.
