Abstract


Winter wheat cultivars were significantly infected by Puccinia triticina causing leaf rust in seasons 2000-2002 in southern and also central regions of Poland. Resistance genes Lr9, Lr19 and Lr24 were found to be effective against dominating populations of the pathogen and typical isolates of P. triticina. Mentioned three resistance genes as well as genes Lr10 and Lr37 were identified using STS (Sequence Tagged Site) DNA - PCR markers in cultivars and resistance sources. Mentioned markers were found very useful in resistance breeding of wheat.

Keywords
