Abstract
A radiation induced mutant of Russet Burbank was recovered that is more susceptible to blackspot bruise than the original cultivar. The mutant was evaluated and characterized for several agronomic and biochemical traits. Compared to Russet Burbank the mutant had slightly lower tuber yield, smaller average tuber weight, a higher number of tubers per plant, higher percent tuber dry matter, similar total tuber dry matter yield, lower tuber protein and higher free tyrosine content. Vine growth and appearance was indistinguishable from Russet Burbank. This mutant should provide an excellent tool for better understanding the tuber characteristics contributing to blackspot bruising in potatoes.
Compendio
Un mutante de Russet Burbank inducido por radiación fue recuperado y resultó ser más susceptible al daño por la mancha negra que el cultivar original. El mutante fue evaluado y caracterizado para varios atributos agronómicos y bioquímicos. Comparado con Russet Burbank el mutante tuvo un rendimiento ligeramente menor en tubérculos, un promedio menor de peso de tubérculo, un mayor numéro de tubérculos por planta, porcentaje más alto de materia seca en el tubérculo, similar rendimiento de materia seca para el total de tubérculos, menor contenido de proteína en el tubérculo y un contenido más alto de tirosina libre. El crecimiento de la parte aérea y su apariencia fue indistingible de los de Russet Burbank. Este mutante proveerá un excelente instrumento para entender mejor las características de los tubérculos que contribuyen al dano por la mancha negra en la papa.
