Abstract  Thirty tree samples of `Gala' apples (Malus domestica L.) were used to determine distribution and standard deviations (SD) of individual fruit weight in orchards throughout New Zealand. A positive correlation was found between average fruit weight and the SD. The coefficients of variation (CV), the ratio of SD to average fruit weight, showed less variation than SD. The recorded fruit size distributions were used to estimate the percentage of fruit in each count size. An example table for three mean fruit weights and five CVs is provided.

Keywords  Malus domestica L.; apple; standard deviation; CV
