Nectarine is a smoothskinned peach

The nectarine is a smoothskinned peach. Experiments show that nectarines may grow from peach stones, and peaches from nectarine stones. Peach trees can produce nectarines by budvariation and nectarine trees also produce peaches, and the fruit so produced will come true to seed. Also, either peach or nectarine trees may produce a fruit half peach and half nectarine, and subsequently produce a true peach. The trees, leaves, and seeds of these fruits are indistinguishable.
