‘Southern Home’ has a complex background with
ancestry from several species including V. rotundifolia, V. munsoniana, V.
vinifera, and V. popenoei. ‘Southern Home’ is six generations removed from V.
vinifera, and is heavily muscadine in traits, although the leaf shape has a
distinctive maple leaf pattern making it highly ornamental. ‘Southern Home’ is
reported to be highly resistant to ripe rot, bitter rot, and black rot, and has shown
no symptoms of Pierce’s disease (Xylella fastidiosa Wells et al.).
‘Southern Home’ was selected from the cross ‘Summit’ x P9-15. ‘Southern Home’ is special among muscadine cultivars because the P9-15 parent is a complex hybrid between V. rotundifolia, V. popenoei, V. munsoniana, and V. vinifera. The first three species are all from the muscadinia subgenus, and V. vinifera is the standard wine bunch grape species. You can tell the hybrid nature of this cultivar by the cut leaf pattern of the leaves.
