Hybrids were obtained in the 1940s at the University of Minnesota, and have been used in subsequent breeding, such as in the parentage of a plum called 'Minnesota No.

[1] In that work, hybrids were also obtained between the Canadian wild plum (Prunus nigra) and the peach.

[1] Another such hybrid was produced at an orchard near Broadus, Montana in the mid 1980s.

A leaf from this tree is included in the Purdue University book "Fruit Breeding", Volume 1.

[2] The hybrid at Broadus, Montana has never fruited as the flowerbuds have all winterkilled.
