PEAR AND QUINCE ROOTSTOCKS - Kahraman Fidancılık

OHF -333 ROOTSTOCK
– It was obtained by hybridizing Old Home X Farmigdale pear varieties in Oregon, USA.
– It is a semi-dwarf rootstock and creates a tree crown volume between 55-60% of the standard pear seedling rootstock.
– It is resistant to fire blight bacterial disease, and is sensitive to Pear decline and pear woolly aphid.
– It is partially resistant to heavy soils, and this rootstock should not be used in soils with high lime content.
– It has a positive effect on the yield of the variety on it.
– It is not as effective in early fruit bearing as quince-based rootstocks.
– There are OH F 40, OH F- 87 and OH F- 97 rootstocks that have semi-dwarf rootstock characteristics.
– In gardens to be established with varieties hung on this rootstock, 3-3.5m spacing and distance should be left on the row and 5m between the rows.
– If the cordon training system is to be applied, the planting distance on the row is reduced to 1.2m, 1.5m.

BA-29 ROOTSTOCK
– It is a quince-origin rootstock improved in France and does not have any incompatibility problems with most pear varieties.
– Dense planting gardens can be established on these rootstocks, as in M9 rootstocks for apples.
– 4 x 1.2m or 4x 1.5m spacing and distances can be applied.
– It is partially sensitive to fire blight.
– It can be propagated with Stool Bed (trench dip) and green cuttings.
– It can be used for quinces.

QUINCE ROOTSTOCKS
– They are rootstocks of quince origin and the most common one is the Quince A clone rootstock.
– Apart from this, there are Quince B and C rootstocks. The most dwarf rootstock among these rootstocks is Quince C.
– Quince rootstocks are incompatible with some pear varieties.
– For varieties that are incompatible with Quince A rootstock, Beurre Hardy or Old Home pear varieties should be used as intermediary rootstocks.
– Varieties that are incompatible with Quince A rootstock are Bartlet (Williams), Beurre Bosc, Conference, Coscia, Farmingdale, Dr. Jule Guyot, Deveci and Asian pears.
– Varieties that are incompatible with Quince A rootstock are; Beurre Hardy, Old Home, Abete Fetel, Santa Maria, Conference, Passe Crasssane, Akça pears.
– Quince-based rootstocks such as MC and Sydo have been tried in western countries and these rootstocks suitable for dense planting have started to be used.
– MC rootstock is a medium-strength rootstock with a shallow root system that makes the variety on it bear fruit early.
– The crop is started to be harvested in the 2nd year following planting and successful results have been obtained in terms of yield.

FOX 11
It is a Pyrus Communis selection obtained by Prof. Marangoni in Bologna. It encourages medium-high strength growth. It has excellent settlement. It has the feature of being adaptable to various soils. It is resistant to calcareous soils. It is a new rootstock that has been determined to be productive in all varieties.

MC
It is a dwarf rootstock. Its development is less vigorous. It is not resistant to calcareous and heavy soils. It definitely needs water. Although it is ideal for full dwarf side-by-side planting, it is recommended in lands where soil properties have been well studied. Planting distance is 3.50 x 0.75 meters.
