Abstract

Reeves Kingpin is a mid-season processing potato variety developed and selected at the University of Maine’s Aroostook Research Farm in Presque Isle, Maine. Its main attribute is its high-yielding potential, giving an average yield of 47 mt/ha. Reeves Kingpin is suitable for processing into french fries due to its large tubers, high specific gravity, and acceptable fry color. The average specific gravity of Reeves Kingpin is 1.085 which is comparable or better than ‘Russet Burbank’ and ‘Shepody’. Reeves Kingpin has received good baking scores, which may qualify it for fresh market; however, its tuber appearance generally does not meet fresh market standard. The tubers have netted to lightly russeted skin and are long and blocky in shape. The tubers rarely exhibit the pointed and knobby characteristics of Russet Burbank. The incidence of misshapen tubers, sunburn, and growth cracks can be high under some conditions; however, hollow heart, internal heat necrosis, and vascular discoloration are not usually a problem. Tubers of Reeves Kingpin are relatively tolerant to shatter and black spot bruise. The plants of Reeves Kingpin are relatively taller, with greener leaves, more flowers, and moderate to heavy fruit set compared to Russet Burbank. The late-season vigor of Reeves Kingpin is an advantage compared to Shepody, but its haulms can be hard to kill prior to harvest, particularly if over-fertilized. Reeves Kingpin is resistant to tuber net necrosis and moderately resistant to verticillium wilt and early blight. However, it is susceptible to golden cyst nematode, late blight, bacterial ring rot, and corky ring spot virus and moderately susceptible to common scab.

Resumen

Reeves Kingpin es una variedad de papa para procesamiento de madurez medianamente temprana, desarrollada y seleccionada en la Granja Experimental Aroostook de la Universidad de Maine en la Isla Presque, Maine. Su mayor atributo es el tener un alto rendimiento potencial con un promedio de 47 t/ha. Reeves Kingpin es apropiada para papa frita por tener tubérculos grandes, gravedad específica alta y color de fritura aceptable. Tiene un promedio de gravedad específica de 1.085, comparable o mejor que Russet Burbank y Shepody. Reeves Kingpin tiene buen puntaje de papa para horneado que la calificaría para su mercadeo en fresco, a pesar de que la apariencia del tubérculo no alcanza los estándares exigidos para este fin. Los tubérculos tiene la piel reticulada a ligeramente rosada, son alargados, de forma cúbica y rara vez exhiben las características de aguzados y nudosos propios de Russet Burbank. La incidencia de tubérculos deformes, rajaduras de crecimiento y por rayos solares, pueden ser altas bajo determinadas condiciones, pero generalmente no presentan problemas de corazón vacío, necrosis interna por calor y descoloramiento vascular. Los tubérculos de Reeves Kingpin son relativamente tolerantes a las rajaduras y magulladuras por mancha negra. Las plantas de Reeves Kingpin son relativamente altas con hojas más oscuras, mayor número de flores y fructificación moderada a alta en comparación con Russet Burbank. El vigor tardío de Reeves Kingpin es una ventaja cuando se compara con Shepody, pero sus rastrojos pueden ser difíciles de destruir antes de la cosecha, particularmente si las plantas han sido sobre fertilizadas. Reeves Kingpin es resistente a la necrosis en red del tubérculo y moderadamente resistente a la marchitez por Verticillium y tizón temprano, pero es susceptible al nematodo dorado, tizón tardío, pudrición bacteriana en anillo y al virus de la mancha corchosa en anillo y moderadamente susceptible a la sarna común.
