Abstract
The purpose of the research is to evaluate different varieties of alfalfa according to a complex of economically valuable characteristics. The study was carried out in the conditions of a foothill zone of the Central Caucasus in the fields SKNIIGPSH VNC RAN. The object of the study is 8 varieties of alfalfa Sarga (control), Manycheskaya, Kizlyarskaya, Sinegibridnaya, Vega 87, Lada, Nakhodka, Mira. The tab of experiments, observations and records were carried out according to generally accepted methods. Results and practical significance. The article presents a comparative characteristic of four varieties of alfalfa according to the main economically valuable characteristics and seed productivity. As a result of the research, it was found that in terms of the yield of green mass and leafiness, the varieties of alfalfa Sinegibridnaya and Kizlyarskaya surpassed other varieties by 5-7%. High seed productivity among the tested varieties of alfalfa was possessed by the variety – Kizlyarsky. The Kizlyarsky variety combines high yield indicators of green mass, dry matter and weight of 1000 seeds. Scientific novelty. Improvement of existing and creation of new varieties of alfalfa with high seed productivity for the conditions of the foothill zone of the Central Caucasus. Methods. Records and observations were carried out according to the method of VIR and the V. R. Williams Feed Research Institute.
Highlights
The purpose of the research is to evaluate different varieties of alfalfa according to a complex of economically valuable characteristics
Alfalfa belongs to the legume family and has the inherent ability to accumulate more or less nutritious nitrogenous substances due to the vital activity of nodule bacteria that settle on its roots
In the Republic of RSO-Alania, the area of alfalfa crops is expanding, the demand for seeds is increasing, but their production remains at a low level

Improvement of existing and creation of new varieties of alfalfa with high seed productivity for the conditions of the foothill zone of the Central Caucasus. Alfalfa belongs to the legume family and has the inherent ability to accumulate more or less nutritious nitrogenous substances due to the vital activity of nodule bacteria that settle on its roots It is a high-yielding and high-protein forage crop. In the Republic of RSO-Alania, the area of alfalfa crops is expanding, the demand for seeds is increasing, but their production remains at a low level. This is due to the lack of adaptive, highly productive varieties of alfalfa that are resistant to diseases, lodging and insufficient knowledge of a number of issues of its cultivation technology for seeds [5, 8, 9, 11, 15, 18, 19]
