Abstract

Hollow heart (HH) when found in potatoes is predominately in the largest tubers. Various tuber lots of cv Norgold Russets ranged from 3.4 to 55.9% HH by weight. In the lot with the least HH approximately 43% of the tubers over 8.89 cm in diameter were hollow compared to 0.2% of those between 3.81 and 5.07 cm. By first removing the very largest, followed by successively smaller tubers there was a continuous reduction in HH in all tuber lots. There were only small differences among the five years in the effect of sizing on HH, and these appeared to be associated with yield differences among years. Figures illustrate the specific effect of removing progressively smaller tubers on the amount of HH remaining.

Resumen

Corazón hueco se encuentra predominantemente en los tubérculos más grandes. Varias muestras de tubérculo de la variedad Norgold Russet variaron entre 3,4 a 55,9% de coraz⤵ hueco en peso. En las muestras con menor corazón hueco aproximadamente 43% de los tubérculos sobre 8.99 cms de diámetro estaban huecos comparado con 0,2% de aquellos entre 3.81 y 5.07 cms. Removiendo primeramente los más grandes, seguido sucesivamente por tubŕculos mas pequeños hubo una continua reducción de corazón hueco en todas las muestras de tubérculos. Hubo solamente pequeñas diferencias entre los 5 años en el efecto del tamaño en corazón hueco y éstos parecen estar asociados con diferencia de rendimientos entre años. Figuras ilustran el efecto de la remoción progresiva de los pequeños tubérculos sobre la cantidad de corazón hueco remanente.
