2009 Annual Report

1. Release of Potato Variety, Classic Russet The sector of the potato industry involved in the production and sale of potatoes for fresh consumption are in need of improved, early-maturing, varieties relative to the industry standard, Russet Norkotah. ARS scientists in Aberdeen, ID, developed a new potato variety, Classic Russet that is an earlier maturing variety with attractive tuber type, a low incidence of defects, and a high protein content relative to industry standard varieties. Classic Russet has comparable or higher yields of marketable tubers than Russet Norkotah and has been rated highly for its culinary attributes. In addition, unlike Russet Norkotah, it can be used as an early harvest variety by the processing industry. The release of Classic Russet provides the U.S. potato industry with an earlier-maturing variety useful for both fresh-pack and processing.

2. Release of Potato Variety, Alpine Russet Russet Burbank is an industry standard for the processing industry, primarily because its long tuber dormancy allows it to be stored for long periods following harvest and then processed into frozen potato products. ARS scientists in Aberdeen, ID, developed a new potato variety, Alpine Russet. This variety also displays the long tuber dormancy of Russet Burbank, but is higher yielding than Russet Burbank and has superior processing characteristics following long-term storage. Alpine Russet provides the U.S. potato processing industry with an improved alternative to the industry standard, Russet Burbank.

3. Release of Potato Variety, Clearwater Russet Improved potato varieties are important in maintaining the competiveness of the U.S. potato industry. ARS scientists in Aberdeen, ID, developed a new potato variety, Clearwater Russet that addresses this need with its high marketable yield, attractive tuber type, and excellent processing characteristics including resistance to sugar ends. This variety also has a higher protein content than standard russeted varieties currently by the U.S. industry. It’s attractive tuber type coupled with its processing characteristics makes Classic Russet a good dual-purpose variety for use by both the fresh-pack and processing sectors of the U.S. potato industry.
