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.

小麦、黑麦和小黑麦种群抗虫性的遗传基础

这篇综述描述了小麦-黑麦和小黑麦遗传种群的黑麦染色体中的 8 个基因和 21 个抗害虫基因座。提供了黑麦染色体供体、插入的染色质类型、分子标记(如果存在)以及用于在育种中部署抗性的小麦和/或小黑麦品系的详细信息。主要的昆虫抗性因子由 1R 染色体决定,其次是 6R,以小麦-黑麦染色体易位或取代的形式确定。大多数基因对俄罗斯小麦蚜虫和黑森蝇具有抗性。记录的遗传资源可以有效地充当小麦和小黑麦改良的重要桥梁。由此提供的数据将帮助研究人员通过经典和标记辅助育种有效地利用黑麦染色质的抗性。
