Citation: Interpretive Summary: Russet Legend is a new russet skinned potato variety that has recently been released by the Tri-State Potato Variety Development Program in the Pacific Northwest. The cross was made in Colorado. The selection was first made in Oregon. Initial testing was done in Oregon, and later large scale testing, seed production and fresh market and processing evaluations were done in Oregon, Idaho, and Washington. Russet Legend is suited for both frozen French fry production and fresh market use. It has better shaped tubers and a more attractive skin color than Russet Burbank for fresh market use, and has more usable tubers and better fry color for frozen French fry use.
Technical Abstract: Russet Legend, a moderately late maturing variety especially suitable for frozen French fry processing but also acceptable for tablestock use (boiling, and baking), was jointly released by the Agricultural Experiment Stations of Oregon, Colorado, Idaho, and Washington, and the U.S. Department of Agriculture in 1998. In three years of regional trials at up to 13 locations in seven western states, Russet Legend averaged 47.3 Mg/ha marketable yield compared with 36.5 Mg/ha for Russet Burbank and 33.6 Mg/ha for Russet Norkotah. Russet Legend has consistently achieved lighter fry color and higher specific gravity than Russet Burbank. Russet Legend is less susceptible to Verticillium wilt than Russet Burbank or Russet Norkotah. It is susceptible to PLRV and net necrosis, and expresses PVY foliar symptoms clearly. Russet Legend is less susceptible to tuber infection and decay caused by Phytophthora infestans than Ranger Russet and Russet Norkotah. Russet Legend is less susceptible to hollow heart, brown center, growth cracks, and sugar ends than Russet Burbank.
