In order to evaluate the reliability of cold tolerance identification indicators and analytical methods for different potato germplasm resources,and to screen different cold-tolerant potato materials,this study used conductivity method and field natural frost method to identify and analyze the cold tolerance of 103 potato germplasm resources by membership function method and clustering analysis method.The results showed that the semi-lethal temperature and frost phenotypic classification combined with membership function method and clustering analysis method could effectively evaluate the cold...
