The cultivation of alfalfa varieties that are relatively resistant to the effects of negative biotic and abiotic environmental factors sharply reduces crop losses and the cost of forage. Work on the study of productivity, disease susceptibility of alfalfa, longevity, as well as the creation of a promising source material has been carried out by us for more than 30 years under natural conditions and against an artificial background, in clean sowing and in a grass mixture, on acidic soils and at normal acidity. Long-term work made it possible to identify and create in this culture sources of resistance to fusarium, brown spot with increased productivity and use them in further breeding work.
