However, different varieties have different storage tolerance, among which late-maturing varieties are more resistant to Tibetan than early-middle-ripening varieties, and middle-maturing varieties are more resistant to Tibetan than early-maturing varieties. The late-maturing varieties such as Red Fuji and Guoguang have not changed greatly in hardness and quality during storage, and have strong disease resistance and are suitable for long-term storage. Medium-ripe varieties such as Red Star, Marshal, Ruby, Jonagold, and Beidou are easy to mature and have large changes in quality during storage.
