The historical and new winter wheat cultivars bred in 20th century were compared in field experiment in 2001-03. Investigated cultivars were divided into three main groups: I - contained 4 old cultivars bred to year 1939: Dankowska Selekcyjna, Wysokolitewka Kleszczynskich, Sobieszynska 44 and Eka, II - included cultivars selected in 1970-89: Grana, Begra, Emika, Jawa, Almari. Modern cultivars: Kobra, Sakwa, Kaja, Korweta, Zyta, Tonacja and British cultivar Kris were placed in a group III. The genotypes were grown in three different nitrogen rates: 0, 80, and 170 kg N/ha. This study shown that grain yield increased during 20th century and was higher by 49.8 percent modern winter wheat cultivars
