Peach breeders need rapid, non-destructive methods to rate fruit quality changes after picking in order to select genotypes that can be delivered to the consumer with the maximum quality. Changes in ground color and firmness over time can be quantified by use of a bouncemeter (which measures coefficient of restitution) in conjunction with a colormeter. During 1991 and 1992, the ripening patterns of over 100 peach and nectarine varieties and selections were measured, allowing comparisons between different genotypes. Ten fruit, picked when firm ripe, were measured both before and after storage for 5 days at 5°C followed by 2 days at 20°C. Soluble solids (%) for each fruit were then measured with a refractometer, followed by determination of titratable acidity on 2 pooled samples. In general ground color changed from green to yellow and firmness decreased over time, but genotypes varied widely in the relationship of ground color and firmness. There also appeared to be differences in rates of change of these parameters.
