Tuber shape is an important agronomic trait in many commercial crops, with a significant impact on the market value and economic benefits. In this study, the genetic and environmental factors controlling tuber shape were systematically analyzed, and the localization and functional annotation of major genes and loci in quantitative traits (QTL) were revealed. We further explored the mechanism of genetic and environmental interaction, and found that gene expression is significantly responsive to environmental signals, and that genetic and environmental factors jointly influence the formation and stability of tuber shape. In polyploid genomic crops, genetic regulation exhibits complexity and requires further resolution of its contribution to phenotypic variation. The results deepen the understanding of the mechanism of tuber shape formation, and provide the theoretical basis and practical guidance for the accurate breeding of tuber shape in commercial crops. The analysis also points out the technical bottlenecks in the current research, and explores the application prospects of high-throughput omics technology and multi-environment data integration in future research, emphasizing the need for international collaboration and data sharing. This study is important to improve the market competitiveness and breeding efficiency of tuber crops.
