Potato is the most widely grown non-grain crop and ranks as the third most significant global food crop following rice and wheat. Despite its long history of cultivation over vast areas, slow breeding progress and environmental stress have led to a scarcity of high-yielding potato varieties. Enhancing the quality and yield of potato tubers remains the ultimate objective of potato breeding. However, conventional breeding has faced challenges due to tetrasomic inheritance, high genomic heterozygosity, and inbreeding depression. Recent advancements in molecular biology and functional genomic studies of potato have provided valuable insights into the regulatory network of physiological processes and facilitated trait improvement. In this review, we present a summary of identified factors and genes governing potato growth and development, along with progress in potato genomics and the adoption of new breeding technologies for improvement. Additionally, we explore the opportunities and challenges in potato improvement, offering insights into future avenues for potato research.
马铃薯是种植最为广泛的非谷物作物，是仅次于水稻和小麦的全球第三大重要粮食作物。尽管其在大面积种植方面历史悠久，但育种进展缓慢以及环境胁迫导致高产马铃薯品种稀缺。提高马铃薯块茎的品质和产量仍然是马铃薯育种的最终目标。然而，由于四体遗传、高基因组杂合性和近亲繁殖衰退，传统育种面临挑战。马铃薯分子生物学和功能基因组学研究的最新进展为生理过程调控网络提供了有价值的见解，并促进了性状改良。在本综述中，我们总结了已确定的调控马铃薯生长发育的因素和基因，以及马铃薯基因组学进展和采用新育种技术进行改良的情况。此外，我们探讨了马铃薯改良中的机遇和挑战，为马铃薯研究的未来方向提供见解。
