Pluots, apriums, apriplums, or plumcots, are some of the hybrids between different Prunus species that are also called interspecific (or IS) plums. In the United States and Canada, these fruits are known by most regulatory agencies as interspecific plums.
Whereas plumcots and apriplums are first-generation hybrids between a plum parent, and an apricot, pluots and apriums are later-generations. Both names "plumcot" and "apriplum" have been used for trees derived from a plum seed parent, and are therefore equivalent.
Pluots are later-generations that show more plum than apricot characteristics; the fruit's exterior has smooth skin closely resembling that of a plum. Pluots were developed in the late 20th century by Floyd Zaiger, and "Pluot" is a registered trademark of Zaiger's Genetics.
