Western Russet / A7961-1
Western Russet (A7961-1) is a multi-purpose variety released in 2004 by the USDA-ARS and the agricultural experiment stations of Idaho, Oregon, and Washington. This variety is medium to late maturing, and produces medium to high yields of oblong tubers with medium russet skin and moderate specific gravity.
Western Russet is resistant to sugar ends, tuber malformations and most external and internal defects. It is resistant to common scab and is moderately resistant to PVY, Verticillium wilt, foliar blight, tuber late blight, and PLRV-caused tuber net necrosis.
Western Russet is susceptible to soft rot, foliar infection by late blight and PLRV, and more susceptible to tuber early blight relative to Russet Burbank.
Previous tests have shown Western Russet to possess 63% higher vitamin C content compared to Russet Burbank.
