Certified seed potatoes are grown from carefully selected tested certified stock; officially inspected in the field

Irish Cobbler has for years held the reputation of being the best quality early potato for both home use and 
market. We have found that Certified Cobbler seed grown on Prince Edward Island, Canada, will yield more 
bushels per acre than is possible from seed grown farther South. 
Bliss Triumph is a very early pink-skinned variety. Bliss does not usually yield as well as Irish Cobbler 
but is earlier. 
Katahdin and Chippewa are comparatively new midseason varieties that have found favor in many localities. 
Sebago is very popular in areas which formerly grew Smooth and Russet Rurals. 
The new Ontario has created wide interest in the whole Northeast. Ontario not only yields well, but is very 
resistant to Potato Scab. 
Essex is a new blight resistant potato that is not only highly blight resistant but also yields very well.
