Abstract

The Mainestay potato variety is high-yielding and late-maturing producing attractive, round, white-skinned, white-fleshed tubers with medium-shallow eyes. Its major use is expected to be as a maincrop tablestock variety. Mainestay appearance ratings are similar to those of Katahdin, and greening in Mainestay tubers is less than in Kennebec. Most boil and bake qualities were rated equal to Katahdin in at least half of the tests, and Mainestay usually has a low incidence of internal defects. However, purple streak, heat necrosis, vascular discoloration, and heat sprouts have been seen on occasion. Mainestay tubers do not show the net necrosis caused by potato leafroll virus, and have shown very little hollow heart or blackspot bruising. Mainestay is susceptible to common scab and acid scab, but moderately resistant to verticillium wilt (Verticillium, albo-atrum andV. dahliae), early blight (Alternaria solani), rhizoctonia (Rhizoctonia solani), dry rot (Fusarium sambucinum), and pink rot (Phytophthora erythroseptica). It is moderately susceptible to the common race of late blight (Phytophthora infestans). Mainestay tubers are slow to mature after vine kill, and additional time is required prior to harvest in order to allow for proper periderm development and to reduce storage losses.

Resumen

Mainestay es una variedad de papa de alto rendimiento y maduración tardía que produce atractivos tubérculos de forma redonda con cáscara y pulpa blanca y con ojos medianamente profundos. Se espera que su uso principal sea para el consumo directe. La calificación para la apariencia de Mainestay es similar a la de la variedad Katahdin y el verdeamiento de sus tubérculos es menor al de Kennebec.

La mayorá de sus cualidades para la cocción y ebullición fueron calificadas como iguales a las de Katahdin en al menos la mitad de las pruebas efectuadas, pero Mainestay por lo general tiene una incidencia baja de defectos internos. Sin embargo, se han observado ocasionalmente estrías púrpuras, necrosis causada por el calor, descoloración vascular y brotamientos causados por el calor. Los tubérculos de Mainestay no muestran la necrosis reticulada causada por el virus del enrollamiento de la papa, y han mostrado muy pocos síntomas de corazón vacío o manchas negras causadas por golpes. Mainestay es susceptible a la sarna o sarna ácida, pero se muestra moderadamente resistente a la verticilosis (Verticillium albo-atrum yV. dahliae), rhizoctoniasis (Rhizoctonia solani), pudrición seca (Fusarium sambucinum) y pudrición rosada (Phytophthora erythroseptica). Es moderadamente susceptible a la raza común del tizón tardío (Phytophthora infestons). Los tubérculos de Mainestay tienen una maduración lenta luego de la muerte del follaje y se necesita un tiempo adicional previo a la cosecha para permitir el desarrollo adecuado de la peridermis y para reducir las pérdidas de almacenamiento.
