The present paper presents the results of a three-year experiment on a good rye complex soil which investigated the yielding potential of five lentil cultivars and the content of five basic organic compounds and minerals in seeds. The highest yield was recorded for Izka cultivar and Krak 2 strain. The highest content of protein was found in Anita seeds. The cultivar, just like the Canadian genotype, contained the greatest amount of nitrogen-free extractable compounds. The seeds of Anita and Izka showed the most favourable content of basic macro- and microelements. ’Anita’ and ’Izka’, developed at the Lublin and Cracow Agricultural Universities, are the first domestic lentil cultivars.
