University of Florida Potato Variety Trials Spotlight: Elkton

‘Elkton’ is a white-flesh potato variety suitable for chipping directly from the field (Figures 1 and 2). ‘Elkton’ was selected from the USDA-ARS breeding program in Beltsville, Maryland, by Dr. Haynes in 1997. In 2003, seed of ‘Elkton’ was made available for field evaluation under Florida growing conditions. In 60 trials conducted between 2003 and 2018, ‘Elkton’ yielded 112% in comparison with ‘Atlantic’ (Table 1). In these trials, ‘Elkton’ demonstrated resistance to internal heat necrosis and hollow heart, which are common tuber physiological disorders under high temperature growing conditions.https://edis.ifas.ufl.edu/hs1237 This is a minor revision.

Trastornos fisiológicos de la papa – Necrosis por calor interno

La necrosis por calor interno (NCI) es un trastorno fisiológico que causa un pardeamiento inaceptable del tejido del tubérculo y puede causar pérdidas económicas para el productor. Las tres principales causas de la NCI en los tubérculos es la alta temperatura en el suelo, la humedad inadecuada del suelo y la nutrición sub-óptima de la planta, o la combinación de estos factores.

Potato Physiological Disorders – Internal Heat Necrosis

HS-1145, a 3-page illustrated fact sheet by Christine M. Worthington and Chad M. Hutchinson, describes this physiological tuber disorder, IHN, that causes an unacceptable browning of the tuber tissue and can increase economic loss to the grower. Includes references.
