Bud sport

A bud sport is a part of a plant or tree, for example, a leaf, shoot or flower, which due to a genetic mutation clearly differs from the rest of the plant, and which can also be grafted to grow new plants which retain this genetic difference as a new cultivar.

An example of a bud sport is the nectarine, which developed from a bud sport from a peach.

Bud sports can also happen to garden plants, where for example a pink flower can appear on a genetically white-flowered plant.
