Introduction and description
Peaches and nectarines are the same species, even though they are regarded commercially as different fruits.
In contrast to peaches, whose fruits present the characteristic fuzz on the skin, nectarines are characterized by the absence of fruit-skin trichomes (fuzz-less fruit); genetic studies suggest nectarines are produced due to a recessive allele, whereas peaches are produced from a dominant allele for fuzzy skin.
The peach or nectarine (Prunus persica) belongs to the genus Prunus which includes the cherry and plum, in the family Rosaceae. The peach is classified with the almond in the subgenus Amygdalus, distinguished from the other subgenera by the corrugated seed shell.
