The purpose of researches: to create a grade of a lucerne with high productive and nitrogen-fixing in potential, powerful root system which will allow to use as much as possible biological nitrogen-fixing as a way of reception of gratuitous biological nitrogen and to raise a lucerne role as the predecessor in a crop rotation. Methods of researches: vegetations-field with use sandy's substrates with the minimum maintenance of nitrogen for studying nitrogen-fixing abilities against inoculation legume bacteria, shtam №404б. The basic method is field - for studying of adaptive properties and genetic potential of fodder and seed efficiency grades samples lucernes in various selection nurseries under irrigation. Results of researches: maximum effected symbiosis behind productivity of green weight (+220,5-229,5 %) selections from a grade of Serafima irrespective of crops term were characterised. Under action inoculation changes of indicators of morphological signs of root system were observed also, but they were various level depending on a genotype. High numerical indicators of signs characterised selections at grades of Serafima and Zorjana: after diameter of a root (+38,8-48,7 %), air-dry weight (+72,2-218,2 %), volume of root system (+116,7-119,4 %), and also nitrogenazes activity in 4,5-5,6 times. The developed technique of selection of a lucerne on the raised level of accumulation of root weight (St. №132134), with its help the perspective selection material of a lucerne (H/MQ-89, Ж/ЦП-11, MQ-87, RГ-90, Vr/01) which unites high fodder and seed efficiency is created. Behind the data industrial variety test the grade of lucerne Vr/01 under the name of Anzhelika in 2010 is transferred on state variety test with productivity drying substances 11,4, seeds of 0,42 t/ha with the long period of autumn vegetation.
