One was developed in 1934 by a William Pollack in Renfrewshire, Scotland.
It is round, with pink skin, and pale yellow flesh. It is a floury potato, from a plant that delivers high yields.
The other cultivar of potatoes called “Redskin” was developed by the United States Department of Agriculture (USDA) at its Agricultural Experimental Stations in Beltsville, Maryland and in College Station, Texas, from a cross between Pontiac potatoes and a potato referred to as “USDA seedling B400-1”, and released in 1960.
It has red skin. The plant delivers high yields in a late harvest.
