In a collaboration between the Chinese Academy of Agricultural Sciences and the James Hutton institute, a study of a diploid wild potato with a high resistance to P. infestans led to the discovery of new resistance genes

A key requirement for a longtime potato storage is that the storage conditions match the needs and end use of the crop. These requirements of can be assessed before harvest by doing several test digs which allow to determine the distribution and level of tuber infection.
