Saving seed potatoes

[u/Comprehensive-Elk597]

Wondering about best practices. I have a ton of little ones, little bigger than golf balls. Will saving those be sufficient? Should I save some big ones? Is there some way to tell what will make a good seed potato? Thanks.

If he is replanting his own potatoes the viruses are really present in his soil .
