Leaf-rust highly resistant introgressive wheat lines have been studied genetically using effective Lr genes from Thatcher’s isogenic lines and “Kazakhstanskaya 126” monosomic lines. Resistance genes Lr9, Lr19, Lr9, Lr24 and Lr26 in line L-344 were shown not to be allelic. Lr9 and Lr26, allelic genes conferring resistance to leaf rust have been identified in line L-345. The “leaf rust” resistance gene in the L-344 line is localized on a morphologically marked 5A chromosome, while the same gene in the L-345 line is located on 2B and 4B chromosomes.References
