At A Glance
Colorado cultivars and clonal selections accounted for 36% of the 7,858 acres of Colorado certified seed accepted for certification in 2018; while releases accounted for 37% of the estimated 51,900 acres planted to fall potatoes in Colorado for 2017. Primary Colorado cultivars planted were Canela Russet (10.4%), Russet Norkotah-S8 (10.4%), Russet Norkotah-S3 (7.5%), Centennial Russet (4.3%), and Rio Grande Russet (4.2%).
Four of the top 20 russet cultivars grown for seed in the U.S. [Silverton Russet (#7), Canela Russet (#11), Centennial Russet (#12), Rio Grande Russet (#18)] in 2018 were developed by the Colorado program. Twenty-nine percent of the Russet Norkotah acreage (including line selections) was attributed to Colorado Russet Norkotah Selections 3 and 8.
