Kalkaska: A Round White Chip-Processing Potato Variety with Common Scab Resistance

Abstract

Kalkaska is a high yielding, round white potato with an attractive appearance with shallow eyes. Kalkaska has a vigorous vine and a late maturity. This variety has resistance to Streptomyces scabies Thaxter (common scab of potato) similar to Pike. Kalkaska has industry approved chip-processing storage characteristics (light color and low incidence of defects) and it also has better tolerance to blackspot bruise than Snowden. Specific gravity in Michigan averages 1.083, ranging from 1.075 to 1.096. Kalkaska also has a higher marketable yield than Pike and does not express heat necrosis in the tubers. The name Kalkaska was chosen to acknowledge a town located in the Michigan seed growing region.

Resumen

Kalkaska es una papa de alto rendimiento, redonda blanca con un aspecto atractivo con ojos superficiales. Kalkaska tiene una planta vigorosa y una madurez tardía. Esta variedad tiene resistencia a Streptomyces scabies Thaxter (roña común de la papa), similar a Pike. Kalkaska tiene características de almacenamiento para el procesamiento de hojuelas fritas (color claro y baja incidencia de defectos) aprobadas por la industria, y también tiene una mejor tolerancia a la mancha negra por magulladura que Snowden. La gravedad específica en Michigan promedió 1.083, con un rango de 1.075 hasta 1.096. Kalkaska también tiene un rendimiento comercial mayor que Pike y no expresa necrosis debido al calor en tubérculos. El nombre Kalkaska fue elegido para reconocer una ciudad situada en la región de producción de semilla en Michigan.
