马铃薯抗低温糖化育种研究进展

摘要

马铃薯块茎储藏期间的低温环境可导致块茎的糖化,进而影响马铃薯炸片和炸条品质,培育抗低温糖化的马铃薯品种对于改良种质资源有着重要的意义。然而,低温糖化产生的生理学机制是一个很复杂的过程,近年国内外研究者在马铃薯低温糖化育种上取得了很大的成就,具体包括在低温糖化生理研究机制方面、育种材料的改良方面、传统育种和基因工程育种等方面,本文对这些显著成就进行综述,希望为马铃薯抗低温糖化育种提供参考。%Cold-induced sweetening（CIS） caused by sugar accumulated in tubers during storage at low temperatures can result in a poor-quality of chipping and French fries.Thus,it is important to improve potato breeding on CIS tolerance.However,physiological mechanism of CIS is a complicated progress,which is not very clear yet.In this paper,we reviewed the achievements of potato breeding for CIS tolerance,which contained researches of physiological mechanism of CIS,improvements of potato germplasm resource,achievements of traditional potato breeding and genetic engineering assisted breeding in recent years,and we hope to give helpful information to other breeders who worked on CIP breeding.
