摘要：

This review describes eight genes and 21 loci for resistance to pests localized in rye chromosomes of wheat-rye and triticale genetic stocks. Detailed information is given for the rye chromosome donor, the type of chromatin inserted, the molecular marker, if present, and resulting wheat and/or triticale lines for deployment the resistance in breeding. The main insect resistance factors are determined in chromosome 1R, followed by 6R, in the form of wheat-rye chromosome translocations or substitutions. Most of the genes provide resistance to Russian wheat aphid and Hessian fly. The recorded genetic stocks can efficiently serve as important bridges for wheat and triticale improvement. The data thus provided will help researchers to competently use resistances of rye chromatin through classical and marker-assisted breeding.
