Abstract

TheMaineChip potato variety is medium-maturing and has round, whiteskinned, white-fleshed tubers with shallow eyes, high specific gravity and moderate yields. Its major use is expected to be as a storage chipping variety since sugar build-up in storage is slow, and reconditioning is possible. This variety can be chipped directly from 7 C storage.MaineChip does not show the net necrosis caused by potato leafroll virus and is moderately tolerant to verticillium wilt (Verticillium alboatrum) and rhizoctonia (Rhizoctonia solani). It is also moderately resistant to blackspot and shatter bruise. Hollow heart is its major internal quality defect, being a problem in ten of the twenty-nine regional tests conducted over five years.

Compendio

La variedad de papa Mainechip es de maduración semitemprana y tiene tubérculos redondos de piel y carne blancas, con ojos superficiales, alta gravedad especícifica y rendimientos moderados. Se espera que su uso principal sea como una variedad de fritura a la inglesa para ser procesada directamente después de su almacenamiento desde que el incremento de azúcar es bajo, siendo posible su reacondicionamiento. Esta variedad puede ser frita directamente a la inglesa al salir de un almacenamiento de 7 C°. Mainechip no muestra la necrosis en red causada por el virus del enrollamiento de la hoja (PLRVB) y es moderadamente tolerante a la marchitez por Verticillium (Verticillium albo-atrum) y a la rhizotoniasis (Rhizoctonia solani). Ella es también moderadamente resistente a la mancha negra y a las magulladuras por golpes. El corazón vacío es su principal defecto interno de calidad, siendo un problema en diez de las veintinueve pruebas conducidas en cinco anos.
