CAB 6P (Prunus cerasus)
Clone of Prunus cersus selected by the University of Bologna. Rootstock for sweet and sour cherries. Trees in the nursery are moderately vigorous. Plant performance is very good. Trees enter early into dormancy and early grafting is recommended. Grafting compatibility is very good with sweet and sour cherry varieties. The root system is moderately developed with good anchorage in the ground. It has some tendency to suckering. Adapts well to heavy soils with low permeability. Resistant to calcareous soils (9% active lime), namatodes and suitable for replanting. Medium sensitive to Armillaria mellea, tolerant to Phytophtora cactorum and Verticillium dahlia; slightly sensitive to Agrobacterium tumefaciens. All cherry varieties grafted on this rootstock show lower vigour (30% lower than those grafted on sweet cherry seedlings), earlier cropping, better fruit quality and colour and higher yield efficiency compared to those grafted on seedlings. Flowering and ripening time are 2-3 days earlier than plants grafted on seedlings. Fruits are of good size and optimal quality. The rootstock is semi-dwarfing, very efficient suitable for specialized and irrigated cherry orchards of medium to medium-high density. Particularly recommended for heavy soils. Produces suckers.
OHF 333 (Old Home x Farmingdale)
Pear rootstock. Needs careful management (irrigation and fertigation) to facilitate plant growth. No suckering. Resistant to Fire Blight (Erwinia amylovora), nematodes and Phytophtora cactorum. Tolerant to drought, heavy and calcareous soils and to low temperatures. Suitable for replanting. The grafted plants develop deep root system with no need for support. All pear varieties show perfect grafting compatibility, 30-35% lower vigour then plants grafted on seedlings. Suitable for medium and low vigour pear varieties.
GF 677 (P. pescica x P. amygdalus)
Hybrid of Prunus persicaXPrunus amygdalus. Rootstock for peach, plum and almond varieties. Vigorous, resistant to calcareous soils (more than 11% active lime) and drought conditions. Sensitive to aterlogging (but less than peach seedlings). Suitable for poor soils and tolerant to replant diseases. Fairly resistant to Fusicoccum and Coryneum, medium sensitive to Verticilium and Phytophtora cactorum, very susceptible to Stereum purpureum, Agrobacterium tumefaciens, Armillaria mellea and to root-knot nematodes. All varieties show perfect grafting compatibility and high yield efficiency. Trees grafted on this rootstock need summer pruning to control shoot growth and to reduce competition between fruits and shoots. It is the standard rootstock for poor, dry and calcareous soils and for heavy soils if permeable and well-drained.
Myrabolano 29 C (Prunus cerasifera)
Clone selected from a progeny of Prunus cerasifera. Rootstock for plums and most apricot varieties. Suitable for all soil types, adapts well to dry soils and heavy soils with low permeability. Moderately resistant to Agrobacterium tumefacens, Verticillium and Leptonecrosis, susceptible to Pseudomonas syringae and resistant to root-knot nematodes. Resistant to calcareous soils( 8-9% active lime).Suitable for replanting. All plum varieties show perfect grafting compatibility and high yield efficiency. With plum varieties this rootstock reduces vigour by 15-20% compared to “Myrabolano B”. Suckering activity is generally low.
SL 64/Santa Lucia 64 (Prunus mahaleb)
Clone of Prunus mahaleb, found and selected by the INRA Experimental Station, Bordeaux, France. Plants grafted on this rootstock are 20% more vigorous than those grafted on CAB 6P and 10-20% less than those grafted on cherry seedlings, depending on soil fertility and orchard practices. Deep root system with good anchorage, composed of vigorous, long, hairy roots which penetrate fairly deeply in the ground. Suitable for poor, permeable and calcareous soils. This is the best rootstock for semi-arid areas characterised by high evaporative demand and low water availability for irrigation. It is sensitive to Phytophtora cactorum, Armillaria mellea, Rosellinia necatrix and Verticillium dahliae, tolerant to bacterial canker (Pseudomonas syringae) and shows low sensitivity to crown gall (Agrobacterium tumefaciens) Tolerance to nematodes is medium. Plants grafted on SL 64 generally crop later than those grafted on ‘CAB 6P’. Yield efficiency is high 4-5 years after planting. It is suitable for specialised cherry orchards of medium-low (300-400 trees/ha) or medium-high (up to 700 trees/ha) densities.
