This article appears in the January 2018 issue of Potato Grower.

In this Smorgasbord, we take a look at Sierra Gold, a russet-skinned, yellow-fleshed variety developed at Texas A&M University’s Texas Agricultural Experiment Station. Used as an alternative to Yukon Gold, Sierra Gold offers great specialty table-stock market appeal.

Certified Sierra Gold seed is available from Cal-Ore Seed, Inc.

Many thanks to Creighton Miller and his team with the Texas A&M potato breeding and variety development program, as well as Amy Leo with Cal-Ore Seed for their help this month.
