Abstract. The purpose of the article is to analyze the study of samples of variable and blue alfalfa in the nursery of competitive variety testing (2022–2023) for a set of economically valuable traits. The Nicolene variety was taken as a standard as one of the most cultivated in the republic. Based on the study of the data of measurements of the root system and height of plants, the relationship between the development of the aboveground and underground parts of plants was revealed. The Vison-P and Vison-C lines, having a more developed root system (32 and 36 cm), were also distinguished by a greater height of 62 and 63 cm, respectively. In the nursery of the competitive variety testing, for the collection of seeds, the sample Vison-Synthetic (1.98 c/ha) was distinguished, which exceeded the variety of Nikolen – st. (1.07 c/ha) by 84.1%. On average, for three years, the yield of green mass was 90.4–115.3 c / ha, which exceeded the standard by 0.1–27.5 %. The highest results were noted in the lines of Vison-M, Vison-D. Dry matter collection amounted to 40.9–44.9 c/ha (standard 40.8 c/ha), exceeding 0.3–10.0 %. According to this indicator, the following samples were distinguished:  Vison-M, Vison-B.  According to the indicators of biometric records and a set of economically valuable characteristics (yield of green mass, collection of seeds and dry matter per hectare), 3 promising numbers were identified – Vizon-M, Vison-D and Vison-Synthetic.
