Huckleberry Gold: A Specialty Market Potato Cultivar with Purple-Skin, Yellow-Flesh, High Tuber Antioxidants, and Resistance to Potato Cyst Nematode (H1) and Potato virus X (Nb and Rx1)

Huckleberry Gold is a purple-skin, yellow-flesh fresh market cultivar with similar culinary qualities to the market standard Yukon Gold. It has lower specific gravity, sucrose and vitamin C content, but a significantly higher level of tuber antioxidants than Yukon Gold. Notable disease resistant characteristics are Potato virus X resistance based on the presence of molecular markers for the PVX resistance genes, Nb and Rx1. In addition it also has the H1 gene present which confers resistance to the potato cyst nematode, Globodera rostochiensis, which has been confirmed by bioassay to pathotype Ro1. The size profile of Huckleberry Gold is smaller than Yukon Gold, allowing a better fit into specialty markets that are geared to smaller size for fresh use. Huckleberry Gold represents the first purple-skin, yellow-flesh cultivar to come from the Northwest (Tri-State) Potato Variety Development program.This is the publisher’s final pdf.

Fresh Potato and Meat Preferences by U.S. Region

We develop an econometric model to identify factors that influence fresh-market demand for red, russet, Yukon, and organic potatoes. Explanatory variables include potato price, pork price, chicken price, steak price, consumer income, Body Mass Index, organic penetration rate, number of Whole Foods stores, and U.S. region. We find the strongest demand for organic and Yukon potatoes in New England, for russets in the East South Central region and for reds in the West North Central region. White meats were complements for Yukons and organics while red meats complemented russets and reds. Own-price elasticities ranged from −0.60 for reds to −1.50 for organic potatoes

Alpine Russet: A Potato Cultivar Having Long Tuber Dormancy Making it Suitable for Processing from Long-term Storage

Abstract Alpine Russet is a later maturing, oblong-long, lightly russeted potato cultivar, notable for having tuber dormancy comparable to Russet Burbank. Processing quality of Alpine Russet from long-term storage is superior to Russet Burbank, with low percent reducing sugars and uniform fry color due to a low percentage difference of sugars between the bud and stem ends. Alpine Russet yields were comparable to Russet Burbank in early harvest trials and were comparable or significantly larger in late harvest trials depending on the location. At two late season locations, Alpine Russet had the largest total and percent No. 1 yields and the largest percent mid-range No. 1 tubers compared to Ranger Russet and Russet Burbank. It has moderately high specific gravity and is resistant to most external and internal defects. Alpine Russet has been evaluated in public and industry trials throughout the Western U.S. for over 15 years. Resumen Alpine Russet es una variedad de papa de madures tardía, larga-oblonga, ligeramente como Russet, notable por tener una dormancia del tubérculo comparable a Russet Burbank. La calidad de procesamiento de Alpine Russet después de un almacenamiento prolongado es superior a Russet Burbank, con bajo porcentaje de azúcares reductores y color uniforme de freído debido a la baja diferencia en porcentaje de azúcares entre la yema apical y la base. Los rendimientos de Alpine Russet fueron comparables a Russet Burbank en ensayos de cosecha temprana y fueron comparables o significativamente mayores en ensayos de cosecha tardía, dependiendo del lugar. En dos lugares de ciclo tardío, Alpine Russet tuvo los mayores rendimientos totales y en porcentaje de No. 1, y el mayor porcentaje de tubérculos de amplitud media No. 1 comparada con Ranger Russet y Russet Burbank. Tiene moderadamente alta gravedad específica y es resistente a la mayoría de los defectos externos e internos. Alpine Russet ha sido evaluada en ensayos públicos y de la industria a lo largo del oeste de los E.U. por más de 15 años
