This study systematically analyzes the development and effectiveness of genetic mapping and marker-assisted selection (MAS) in potato breeding, focusing on the application of these methods in disease resistance, agronomic trait improvement, and yield enhancement, as well as the significant results achieved. The findings indicate that MAS has greatly improved the selection efficiency for resistance to major diseases such as late blight and PVY virus and has shown positive outcomes in enhancing complex agronomic traits like drought tolerance. Practical applications of MAS in breeding disease-resistant potato varieties further confirm its efficacy in developing resistant cultivars, with notable breakthroughs in combating polygenic diseases. This study also explores the challenges faced in implementing MAS, analyzing current limitations in the study of complex traits. It anticipates that innovations in genomics and bioinformatics tools will drive MAS applications in polygenic traits, aiming to further enhance breeding efficiency.
