The narrow-leafed lupin (Lupinus angustifolius L.) is a valuable legumes crop used as forage and green manure which is adapted to wide spectrum of soil-and climatic conditions; the crop has short domestication history. The protein content in its seeds and in dry matter of green mass varies from 30.0 to 37.0% and from 16.0 to 22.0 % respectively and depends on ecotype and soil-and-climatic conditions. This lupin specie can accumulate to 300 kg/ha symbiotic nitrogen in biomass and assimilates phosphorus and potassium of heavy available soil layers. It is very technological suitable for common used machinery systems. The State List of breeding achievements of Russia recommends the following regions for lupin cultivation: the North, the North-West, the Central, the Volga-Vyatka, the Middle-Volga, the Central Chernozem, the Ural, the West Siberia and the East Siberia. The tests were carried out in 2017-2020 in the All-Russian Lupin Scientific Research Institute which is located in the South-West of the Central region. Ten varieties and breeding lines bred in the Institute are tested. The samples differ by early ripeness and anthracnose tolerance. The average experimental variety grain yield was 2.38 t/ha. The vars. Uzkolistny 53-02, USN 53-236, Bryanskiy kormovoy and SBS 56-15 have the highest yield and adaptivity (103-113 %). The index of year conditions was revealed; 2017 with the index 0.56 was the most favorable for implementation of grain productivity of the tested narrow-leafed lupin varieties. In the ecological varieties testing the soil-and-climatic conditions of Shatilovskaya experimental station (Orel region) were the most favorable for implementation of variety grain productivity (4.0-4.5 t/ha). Grain yield was 3.0-4.0 t/ha in ecological locations which differ in soil-and-climatic conditions: there are Kaliningrad region, Mordovia Republic, Krasnoyarsk region etc.
