Narrative
From V. riparia x V. berlandieri. Type = rootstock. Per Winkler (see citation): "The phylloxera rootstock, SO4, is one of the seedlings arising from crosses by Teleki between V. berlandieri and V. riparia. In some respects it is similiar to the other Teleki hybrids, such as Teleki 5A, 5BB, etc. One principal difference, however, is its somewhat lower vigor. This underlies its popularity with growers in Northern Europe. It is quite tolerant to lime, is highly resistant to phylloxera, and roots fairly readily and grafts with ease. SO4 has only recently been placed in field trials in California vineyards. The moderate vigor of its scions indicates that it may not be suitable on high stress sites. For example, in a non-irrigated trial in Napa Valley, it has developed slowly, producing relatively small vines during the first few years. On the other hand, it may be quite satisfactory on irrigated, more fertile sites. This new stock to California deserves a thourough and intensive study in phylloxerated districts."
