Pomerelle Russet: An early maturing potato variety with high yield of U.S. No. 1 tubers suitable for fresh market and early processing and resistance to Potato mop-top virus and corky ringspot.

DOI: https://doi.org/10.1007/s12230-017-9593-1 Interpretive Summary: Pomerelle Russet is a potato variety released in 2015. It is a brown-russet skin fresh market variety with high early season yields. It also produces a high marketable yield of U.S. No. 1 tubers. Tubers are smooth, nicely shaped and have resistances to internal and external defects. It has a moderately long dormancy and stores well. It has resistances to Potato mop top virus, soft rot, corky ringspot and tuber infections of late blight. While it is a good fresh market variety, it can also be processed and produce acceptable fry color out of short term storage.
Technical Abstract: Pomerelle Russet is an early maturing fresh potato variety, which produces moderately high early-season yields of oblong-long tubers with brown-russet skin. It is notable for its very attractive, smooth tubers and resistances to internal and external defects with a high percentage of U.S. No. 1 tubers. Fresh merit ratings for Pomerelle Russet in trials conducted in Idaho, Oregon and Washington were consistently higher than Russet Burbank and Russet Norkotah. Early harvest yields for Pomerelle Russet are generally comparable to Russet Norkotah with a higher percentage of U.S. No. 1 tubers. Compared to Russet Burbank and Russet Norkotah, Pomerelle Russet has greater resistance to Potato mop-top virus, soft rot, corky ringspot and tuber infections from late blight. It also has much lower total glycoalkaloid concentrations and higher protein and vitamin C concentrations than Ranger Russet and Russet Burbank, indicating that it can provide an enhanced level of dietary protein and vitamin C relative to these standard potato varieties. Pomerelle Russet has moderate specific gravity and good resistance to sugar ends. It also has moderately long dormancy, about 30 days shorter than Russet Burbank. Average post-harvest processing ratings for Pomerelle Russet were similar to Ranger Russet and greater than Russet Burbank. Pomerelle Russet also can maintain acceptable fry color for about 180-200 days in storage at 8.9oC, indicating potential for processing out of short-term storage, with improved fry color uniformity relative to industry standards. However, its primary use appears to be as a high quality, early fresh variety.
