Abstract
Freedom Russet was developed from a cross between ND14-1, a parent with scab resistance, and W1005rus, a parent with good processing quality. It is a mid-season cultivar and can be used for dual purposes for both fresh market and processing. The tubers of Freedom Russet are oblong-long with medium-dark russet skin, and have an attractive appearance. Freedom Russet tubers have better external and internal qualities than Russet Burbank tubers. The total and US No. 1 yield of Freedom Russet is equal to or higher than Russet Burbank in most environments. The specific gravity of Freedom Russet is similar or 1–3 unit less than Russet Burbank. Freedom Russet produced better fry color than Russet Burbank when processed after storage at 10, 8.9, and 7.2°C. It showed similar susceptibility to both early blight and late blight compared to Russet Burbank. Freedom Russet is resistant to common scab and moderately resistant to powdery scab. It is similarly susceptible to soft rot and pink rot as Russet Burbank, and clearly expresses bacterial ring rot symptoms. Freedom Russet is tolerant to Verticillium wilt and showed better yield potential than Russet Burbank under early dying pressure.
