Pacific Russet: An early maturing, attractive Russet cultivar with excellent culinary quality

Pacific Russet is a high-yielding, early maturing, oblong russet fresh market cultivar with excellent tuber appearance and culinary quality. In trials conducted in western Canada the yield of the new cultivar was generally superior to Russet Burbank, Ranger Russet, and Atlantic at 80, 90, and 110 days after planting. In the North Central Regional Variety Trial the yield of Pacific Russet exceeded that of Russet Norkotah in four of the eight sites in 2000 and three of the eight sites in 2001. In trials conducted in Ontario (Canada) Pacific Russet exceeded the yield of Goldrush at both sites in 2001 and in 2002 at two of the three sites that included both cultivars. External and internal defects occur at very low levels. The new cultivar is resistant to common scab and moderately resistant to Verticillium and Fusarium wilt, but susceptible to Fusarium dry rot and late blight (foliar). Pacific Russet shows clear foliar but not tuber symptoms when infected with bacterial ring rot.
