We dedicate this report to Frank Barrett who passed away December 31, 2010. Frank was a longtime grower/cooperator with the Texas Potato Breeding and Variety Development Program.

Frank was born Oct. 29, 1922, in Wendell, Idaho, to Fred and May Roberts Barrett. He grew up in Wendell, working on his father's potato farm and graduating from high school in 1940.

After the 1940 potato harvest, he moved with his parents, four brothers and three sisters to Hereford to help establish the family's potato growing and shipping business in the Texas Panhandle.

He remained active in the potato business until his last days, with 2010 constituting the family's 101st consecutive year to produce a potato crop. In 2004, he was named to the Texas Fruit and Vegetable Growers Hall of Fame. He will be missed.
