The nectarine is a cultivar group of peach that has a smooth, fuzzless skin. Though fuzzy peaches and nectarines are commercially regarded as different fruits, with nectarines often erroneously believed to be a crossbreed between peaches and plums, or a “peach with a plum skin”, they belong to the same species as peaches. Several genetic studies have concluded in fact that nectarines are created due to a recessive gene, whereas a fuzzy peach skin is dominant.Nectarines have arisen many times from peach trees, often as bud sports.
As with peaches, nectarines can be white or yellow, and clingstone or freestone. On average, nectarines are slightly smaller and sweeter than peaches, but with much overlap.The lack of skin fuzz can make nectarine skins appear more reddish than those of peaches, contributing to the fruit’s plum-like appearance. The lack of down on nectarines’ skin also means their skin is more easily bruised than peaches.
