Potato (Solanum tuberosum L.) tuber size and yield are influenced by multiple genetic and environmental factors. This study reviews key genes and regulatory networks affecting tuber traits, including quantitative trait loci (QTL) analysis and transcription factor networks involved in tuber development. The application prospects of gene-editing technologies for improving tuber yield and quality are also explored. Existing research highlights the significant gene-environment interactions on tuber traits, while high-throughput genome-wide association studies (GWAS) and marker-assisted selection (MAS) have become effective tools for optimizing breeding strategies. The study further analyzes the impact of different genetic mechanisms on polygenic traits and the integration potential of traditional and modern molecular breeding techniques to address challenges in yield improvement and stress-resistant breeding. By reviewing recent research progress, this work aims to provide theoretical support for cultivating high-yield and high-quality potato varieties and proposes future research directions.
