True Potato Seed: An Option for Availability of Good Seed

Growing potatoes from true potato seeds is fun and you can discover some very good new varieties, but it is not as reliable as growing potatoes from tubers. Potato is a genetically diverse crop and the seedlings do not grow true. That means that every seedling grown from TPS is genetically unique and will produce tubers with different characteristics than the parent. Every potato plant grown from seed is a new variety. There are thousands of potato varieties with different colors and forms found in the Andes, but these types are a challenge to grow in North America because they do not form tubers until very late in the growing season. Andean potatoes are more readily available as TPS than as tubers.
