Abstract:

Low temperature stress is one of the important environmental factors affecting potato growth  and development, restricting the healthy and stable development of potato industry. In recent years, some  achievements have been made in the research of potato cold resistance. In this study, the differences between different methods of cold resistance identification and their application in the screening of cold-resistant varieties were emphatically expounded. The more convenient and reliable evaluation methods of  cold resistance and varieties of cold-resistant potato will be selected. The cold resistance physiological research and prevention measures of potato frost damage were summarized, the practical production reference of potato frost resistance will be provided. In addition, the molecular mechanism and QTL mapping  of potato cold resistance were reviewed, providing abundant genetic resources and theoretical basis for  the genetic improvement of potato cold resistance traits.

Key words: potato; low temperature stress; variety identification; cold resistance mechanism
