The alfalfa breeding laboratory, together with the laboratory of conservation and storage of feed, is con-ducting research on the development of an express method for the determination of sugars in the green mass of alfalfa. The aim of the study is to create promising alfalfa varieties and hybrids with a high content of water-soluble carbohydrates and a low buffer capacity to increase the silage capacity of this valuable protein crop. The research was carried out on varieties of alfalfa (Medicago varia Mart.) selected by the V.R. Williams Federal Research Center: Vega 87, Pastbishchnaya 88, Selena, Sonata, Taisiya, as well as 10 hybrids created by various breeding methods. An assessment is given on yield and chemical composition, sugar-buffer ratio and silage capacity, including the determination of sugars in juice. As a result of the re-search, a method for determining the amount of soluble sugars in alfalfa juice using a refractometer has been optimized. The presence of a statistically significant correlation (r = 0.60–0.89) between the sugar content determined by the Bertrand method and in the juice determined using a refractometer allows us to conclude that this method can be used for accelerated screening of a significant amount of alfalfa feedstock for the content of water-soluble carbohydrates.
