Among perennial bluegrasses, cocksfoot (Dactylis glomerata L.) is one of the most valuable and widespread species used in forage production in the country. This species is characterized by high coenotic activity and competitiveness in grass mixtures, longevity, and tolerance to multiple cuttings. To increase the efficiency of this crop, it is necessary to develop new varieties with improved economically useful traits. In 2026, patent No. 14463 was received for the cocksfoot (Dactylis glomerata L.). Delta VIK. Patent holder: Federal Williams Research Center of Forage Production and Agroecology. The new variety is characterized by increased productivity throughout the entire cultivation period. The average green mass yield in the first cutting over three years of use was 35.52 t/ha, in the second — 12.37 t/ha, in the third — 8.98 t/ha, and in the fourth — 5.07 t/ha, which is on average 13% higher than this figure for the standard VIK 61 variety. The seed yield in the first two years of use was 0.4–0.5 t/ha, and in the third — 2.7–3.1 t/ha, which in different years exceeded this figure for the VIK 61 standard in the first two years of use by 8–20% and in the third by 15–32%. The green mass of the new variety of cocksfoot met the requirements of the technical specifications of GOST 55452-21 "Hay and haylage" class I in terms of crude protein and crude fiber content. The concentration of essential minerals (crude ash, phosphorus, and potassium) and crude fat, in the plant material met animal feed standards.
