The technical report presents a summary of results obtained in the leaf rust race surveys carried out in Czechoslovakia/Czech Republic in the years 1966-2001. The physiologic races were determined using the standard differentials Malakoff (Lr1), Carina (Lr2b), Brevit (Lr2c), Webster (Lr2a), Loros (Lr2c), Mediterranean (Lr3), Hussar (Lr11), Democrat (Lr3) and the additional differential Salzmünder Bartweizen (Lr26). Races 14, 77, 61, 53 and 2 successively dominated in the given period. They mostly appeared in two variants, avirulent and virulent to Lr26. Genes for virulence in the leaf rust races were compared with genes for resistance in the registered wheat cultivars listed in the report. Most frequent were the genes Lr3 and Lr26.
