Why is it important to propagate fruit tree clones from superior plants?

Propagating fruit tree clones from superior plants is essential because it ensures that every new plant in a group—a clone—is genetically identical to the parent, thereby retaining the desired varietal characteristics, such as high productivity and product quality.1

Because many fruit and nut crops do not breed true from seed, relying on seeds would lead to significant variation in character and quality. By using vegetative propagation methods like grafting, budding, or cuttings, growers can reliably multiply successful varieties that have been selected for their market quality and yield.12

Furthermore, this practice is critical for maintaining the integrity of existing varieties. Because there is a risk of accidentally multiplying degenerate or low-quality mutations, it is vital to propagate only from superior individuals to prevent the spread of undesirable traits. In some cases, such as with citrus, these precautions are especially necessary due to the higher frequency of mutation.1
