Minnesota 78 is a variety of grapevine, developed at the University of Minnesota. ^[1] It was extensively used in breeding by Elmer Swenson, with its Vitis riparia background providing a degree of adaptation to the harsh climate of the upper Midwest.^{[ citation needed ]}

It has been recorded as a cross of Beta by Witt. ^[1] However, many have doubted this pedigree, and Swenson suggested that the male parent may be Jessica, a cross of Vitis labrusca by a variety of Vitis aestivalis .^{[ citation needed ]} Because Witt appears to have been lost, precluding genetic testing, the truth may not be known.^{[ citation needed ]}
