Abstract
Red Companion is a medium-early maturing variety with round tubers, stable red skin, and white flesh. Its intended use is as a tablestock variety. Red Companion has consistently outyielded Dark Red Norland in state and regional trials. The vines are more vigorous and mature 10 days later than those of Dark Red Norland. Red Companion has a higher specific gravity and longer tuber dormancy than does Dark Red Norland. The sloughing of Red Companion potatoes after boiling is less than for Dark Red Norland or Red Pontiac. Less shatter bruise was found when handled in cold storage. Red Companion is less susceptible to soft rot (Erwinia carotovora) and corky ring spot (Tobacco Rattle Virus) than Dark Red Norland and has a medium resistance to early blight (Alternaria solani).
Resumen
Red Companion es una variedad de maduración media con tubérculos redondos, cáscara firme de color rojo y pulpa blanca. Se propone su uso como variedad para consumo. En ensayo regionales y estatales, Red Companion ha obtenido mejores rendimientos que Dark Red Norland. El follaje es mucho más vigoroso y madura diez días después que el de Dark Red Norland. Red Companion tiene una gravedad específica más alta y una dormancia más larga que la Dark Red Norland. El escaramiento de la papa Red Companion después del hervido es menor que el de Dark Red Norland o Red Pontiac. Se encontraron menos fragmentes magullados cuando se manejó el almacenamiento en frío. Red Companion es menos susceptible a la pudrición blanda (Erwinia carotovora) y a la mancha de anillo corchosa (virus cascabel del tabaco) que la variedad Dark Red Norland y tiene una resistencia mediana al tizón temprano (Alternaria solani).
