Vigorous, resists root-knot nematode. Excellent for well-drained soils. In poorly-drained soil, plant on a hill. For nectarines, apricots, plums, prunes, almonds.
More tolerant of wet soils than Nemaguard. Also more cold hardy. Susceptible to nematodes in sandy soils. For plums, peaches, nectarines, apricots, prunes, almonds.
Advantages: extremely vigorous, nematode resistance similar to Nemaguard, productive, increases fruit size. Disadvantages: may be intolerant of wet soil conditions, delays fruit maturity in some varieties. (Zaiger)
Advantages: vigorous, precocious tree, nematode resistance similar to Nemaguard, productive, increases fruit size, shows tolerance of wet soil conditions. (Zaiger)
Titan almond x Nemaguard peach hybrid seedling. Advantages: extremely vigorous, may have root-knot nematode resistance, considered well anchored, tolerant of calcareous soil conditions. Disadvantages: trees may be excessively vigorous on good soil, may delay maturity of fruit, more susceptible to crown rot than peach seedling rootstocks, intolerant of wet soil conditions. Not presently used by Dave Wilson Nursery.
Shallow root system, much more tolerant of wet soils than Lovell or Nemaguard. Resistant to oak-root fungus, root-knot nematodes. Mature trees comparatively small. For apricots, plums, most almonds.
Shallow but vigorous root system. Tolerates wet soils. Immune to root-knot nematodes, some resistance to oak-root fungus. Trees reach larger size compared to Marianna 26-24. For apricots, plums, most almonds.
Peaches and nectarines dwarfed to 8 to 14 feet. Apricots and plums dwarfed to 3/4 of standard. Very tolerant of wet soil, induces early dormancy in dry soil. Very winter hardy. Resists root-knot nematodes. Trees bear at young age. (Zaiger)
St. Julian "A"
Semi-dwarf rootstock for cold areas with fluctuating spring temperatures due to inconsistent spring weather conditions. Preferred over Citation in north coastal mountains and Oregon.
Advantages: Very vigorous, with excellent anchorage and few root suckers. Disadvantages: Needs well drained soils. Very susceptible to bacterial canker, phytopthora and oak root fungus.
*Important note: trees on peach x almond hybrid rootstocks including Atlas and Viking are very sensitive to dehydration. While planting keep roots damp; irrigate after planting.
