Abstract

In 1963, a project was started to shift the short day length adaptation of Andean tetraploid varieties to the long day adaptation of North American varieties. The method followed was recurrent selection. The purpose was to add diversity to the available breeding clones. The initial base for selection came from the Commonwealth Potato Collection of Solanum tuberosum group andigenum. As selection reduced the diversity of original clones, a second introduction from multiple sources was integrated. Essentially ten cycles of selection were achieved in 20 years. In that period it was possible to test for resistance to various diseases such as late blight, scab, cyst nematodes, and viruses PVX and PVY. Gradually the emphasis shifted to making hybrids of the long day adapted clones (neotuberosum) with tuberosum varieties. In the next two decades, the earliest variety releases were generally marginally successful. The first significant release was Eva in 1999. Now three more have been named and three are in the process of release. It has been a satisfying 56 years.

Resumen

En 1963, se inició un proyecto para cambiar la adaptación de corta duración de las variedades de tetraploideando andino a la adaptación de largos días de variedades norteamericanas. El método seguido fue la selección recurrente. El propósito era añadir diversidad a los clones reproductores disponibles. La base inicial para la selección vino de la Colección Commonwealth Potato de Solanum tuberosum group andigenum. A medida que la selección redujo la diversidad de clones originales, se integró una segunda introducción de múltiples fuentes. Esencialmente se lograron diez ciclos de selección en 20 años. En ese período fue posible probar la resistencia a diversas enfermedades como la plaga tardía, la costra, los nematodos de quistes y los virus PVX y PVY. Poco a poco el énfasis se desplazó a la fabricación de híbridos de los clones adaptados de un largo día (neotuberosum) con variedades de tuberosum. En las siguientes dos décadas, las primeras versiones de variedades fueron generalmente marginalmente exitosas. El primer lanzamiento significativo fue Eva en 1999. Ahora se han nombrado tres más y tres están en proceso de liberación. Ha sido un satisfactorio 56 años.
