Truncation selection involves selecting and breeding individuals that exhibit traits above a certain threshold, in this case, heavier peaches. If the trait (peach weight) is heritable, meaning it can be passed from parents to offspring, then selecting for heavier peaches should increase the average weight in the next generation.
