Lodging is an important limiting factor in the production of rye (Secale cereale L.), especially in high-input planting systems, which seriously affects yield stability and grain quality. Improving lodging resistance has become an important goal in the genetic improvement of rye. This study systematically analyzed common molecular marker types, such as SSR, SNP and AFLP, as well as their applications in the mapping of anti-lodging related QTLS and candidate genes. The combination of MAS with QTL mapping and genome-wide association analysis (GWAS) provides strong support for analyzing the key genetic loci that affect stem structure and lignin synthesis. It also explores the feasibility of integrating MAS with early generation selection, multi-trait joint breeding and other strategies. Through breeding cases in Germany, Poland and northern China, It demonstrated the successful application of MAS technology in the improvement of rye varieties resistant to lodging. Although it still faces challenges such as group background dependence and environmental interaction at present, MAS remains an important direction for precision breeding. This study aims to enhance the integrated application of genomic selection (GS), high-throughput phenotypic analysis and molecular design breeding to improve breeding efficiency and the accuracy of resistance expression.
