薯片和薯条是风靡全球的马铃薯加工食品，但低温糖化长期困扰着马铃薯加工产业的发展。块茎的低温糖化是一个复杂的数量性状，分子遗传学的发展使得马铃薯数量性状的遗传定位得以实施。近年来，马铃薯低温糖化的遗传研究也取得了不错的进展，包括马铃薯遗传图谱构建和低温糖化相关性状的QTL定位，不同代谢途径上的候选基因的标记与低温糖化QTL共定位，这些研究成果将为进一步明确马铃薯低温糖化机制以及利用遗传定位候选基因标记构建马铃薯低温糖化分子标记辅助选择体系奠定基础。

Fried products such as chips and French fries of potato are extremely popular food in the world, but cold-induced sweetening (CIS), a complex quantitative trait, is a main restraining factor for processing. Advances in molecular genetics make it possible to identify CIS-associated genes and develop genetic markers for trait selection through constructing linkage maps and detecting the chromosome regions where the quantitative trait locus (QTLs) located. The main progress in linkage map construction, QTL mapping and the candidate gene identification were reviewed, which lays foundation for understanding molecular mechanism of CIS and approaching the potentials of candidate gene markers in marker-assisted selection.
