Abstract: Wheat accessions were genotyped with molecular markers linked to wheat leaf rust resistance genes Lr9 , r10 , Lr19, Lr24 , Lr26 , Lr34 , and Lr37 . They included 1920 wheat plants and 46 commercial varieties bred at the Lukyanenko Institute. Basically, the analyzed varieties had the inef fi cient gene Lr10 , poorly ef fi cient Lr26 and Lr34, or their combinations. The highly ef fi cient genes Lr9 and Lr24 were not detected. The Lr19 gene, effective in the Krasnodar region, was identi fi ed in varieties Pallada and Yara. The resistance gene Lr37 was found in variety Morozko. Within a short time, F2 and F3 plants with introgression of genes Lr9 , Lr19 , Lr24 , Lr37 were obtained. Accessions with combinations Lr24 + Lr37 , Lr24 + Lr19 , Lr24 + Lr9 , Lr19 + Lr37 , Lr37 + Lr9 , Lr19 + Lr9 were identi fi ed. Seven plants with the combination of three genes Lr37 + Lr19 + Lr9 and one with Lr37 + Lr24 + Lr9 were selected.
