Abstract
Full-sib russet and smooth-skinned selections from each of thirty-two families were evaluated for storage losses due to shrink (weight loss and rot). Smooth-skinned selections showed slightly less weight loss during one of the two storage seasons but skin type did not influence losses due to rot. Family influence on storage losses due to both weight loss and rot was significant. Selection of skin type to improve storability may be marginally effective, but selection within families with good storability should provide rapid improvement.
Compendio
Se evaluaron selecciones bien relacionadas de papa de piel arrosetada y de piel lisa de cada una de treinta y dos familias, para pérdidas en almacenamiento debidas a la contractión por pérdida de peso y por pudrición. Las selecciones de piel lisa mostraron una pérdida de peso ligeramente menor durante una de las dos temporadas de almacenamiento, pero el tipo de piel no influyó sobre las pérdidas debidas a pudrición. La influencia de la familia sobre las pérdidas en almacenamiento debidas tanto a la pérdida de peso como a la causada por pudrición, fue significativa. La selección del tipo de piel para mejorar la capacidad de almacenamiento puede ser marginalmente efectiva, pero las selecciones dentro de las familias con una buena capacidad de almacenamiento habrán de acelerar el proceso de mejoramiento.
