SO4 is interspecific hybrids within the Americas, whose parents are winter grapes and riparian grapes. SO4 is a multi-resistant rootstock that is resistant to root nodules and aphids. It is nearly immune to root-knot disease, resistant to nematode disease, has strong drought resistance and strong moisture resistance. It is acid tolerant and lime-resistant soil with 17% to 18% salt tolerance. 4%, anti-iron deficiency chlorosis, root resistance to low temperature -9 ℃, anti-fungal disease is very strong, experimental motherland SO4
