Rootstock Characteristics
By Phil Nicholas - South Australian Research and Development Institute, Loxton Centre (1999)
This table has been prepared as a guide for selecting a suitable rootstock. It summarises information from local experience and many other sources and will be modified as more local trials are assessed.

Additional information |
||||||||||
| Phylloxera - the above rootstocks generally have high resistance to phylloxera, but K51-40 has not been tested. | ||||||||||
| Groups - A = V. riparia x V. rupestris crosses, B = V. berlandieri x V. riperia crosses, C = V. berlandieri x V. rupestris crosses, D = V. champini x V. riparia crosses and E = V. champini. | ||||||||||
| Rootstock - note older SO4 plantings now identified as 5C Teleki and older 5A Teleki plantings identified as 5BB Kober. | ||||||||||
| Scion vigour - given as a guide only as relative vigour of rootstocks varies in different environments eg different soil types or water availability. | ||||||||||
| Vegetative cycle - indicates comparative length of growing season, which affects time of scion wood maturity and may influence time of grape maturity. | ||||||||||
| Nematodes - refers to root-knot nematode resistance. Note that nematode populations of the same species can vary in aggressiveness in different regions. Also populations can develop in a vineyard which gradually overcome resistance. | ||||||||||
| Lime - Group A only tolerate about 10% active lime. 140 Ruggeri has higher tolerance than others in Groups B and C. | ||||||||||
| Acid soil - choice may change if lime is applied prior to planting. More local trial data required to better define suitability. | ||||||||||
| Salinity - indicates performance in saline soil. Interaction with drought is not considered here (rootstocks susceptible to drought may have higher salt uptake in drought situation). | ||||||||||
| Magnesium uptake - low magnesium uptake by some rootstocks, especially SO4, in some soils may cause bunch stem necrosis, particularly with Cabernet Sauvignon and Merlot. | ||||||||||
| Drought - Group B is slightly more tolerant than Group A. | ||||||||||
| Water- logging - refers to spring waterlogging of vines several years old. Note that some rootstocks eg 101-14 may be susceptible to water-logging in early years, but more tolerant in later years. | ||||||||||
| Compatibility - incompatibility is rare, but the rootstocks 3309 , 101-14 and 5BB Kober are more susceptible than others to compatibility problems, particularly where scion wood contains virus. Ramsey is incompatible with Muscat Gordo. | ||||||||||
