Abstract

Potato selection for high dry-matter can be made in the first-year seedling generation reducing the time required to complete a breeding cycle to one year. Yielding capacity of first-year seedlings can be as good as that of plants from tubers of clonal generation and from commercial varieties.

Resumen

En un programa tradicional de mejoramiento de papa, la selección inicial para material seca es generalmente hecha 3 a 4 años después de la hibridación. De 1973 a 1975, más de 20,000 plánutlas procedentes de cruces entre 4 variedades comerciales y 4 clones seleccionadas, fueron investigados. Los resultados indican que la selección de papa para materia seca alta puede ser efectuado aún en el primer ano de la generación de plántulas.

El tiempo requerido para completar un ciclo de mejoramiento pude ser acortado a un año cuando plantas de papa de semilla verdaderas, son crecidas bajo conciciones de campo. La capacidad de rendimiento de plántulas del primer año pueden ser tan alta como de plantas de tubérculos de generación clonal y variedades comerciales.
