Pear and Quince Clone Rootstocks

It was evolved by crossbreeding the Old Home X Farmigdale pear species in Oregon State of USA.
It is a semi-dwarf rootstock and form a tree crown at 55-60% of the generative pear rootstock.
It is resistant to fire blight bacterial disease but sensitive to pear decline and pear woolly aphid.
It is partly resistant to heavy textured soils and this rootstock shouldn't be preferred in soils with a high rate of lime.
It positively affects the crop of the specie on it.
It isn't as effective as the quince origin rootstocks in early yielding.
Semi-dwarf rootstocks OH F 40, OH F- 87 and OH F- 97 are available.
In gardens to be established by the stocks grafted onto this rootstock, gaps on the line can be 3-3.5m and gaps between lines can be 5m.
If funicle cultivation system will be applied, plant spacing on the line should be reduced to 1.2m, 1.5m.

It is a quince origin rootstock regenerated in France and doesn't have an incompatibility with pear specie.
Densely planted gardens can be established on these rootstocks.
4x1.2m or 4x1,5m gaps and spaces can be applied.
It is partly sensitive to fire blight.
I can be reproduced with Stool Bed (ditch dipping) and cutting.
It can also be used for quinces.

They are quince origin rootstocks and the most common one is Quince A clone.
In addition, Quince B and C rootstocks are available. The most dwarf one is the Quince C.
Quince rootstocks don't fertilize some pear species.
Beurre Hardy or Old Home pear species should be intergrafted for the species having a grafting inconformity with Quince A rootstock.
The species compatible with Quince A rootstock are Bartlet (Williams), Beurre Bosc, Conference, Coscia, Farmingdale, Dr. Jule Guyot, Deveci ve Asya pears.
Species ompatible with the Quince A specie are Beurre Hardy, Old Home, Abete Fetel, Santa Maria, Conference, Passe Crasssane, Akça pears.
Quince origin MC, Sydo etc. have been tried in western countries and these rootstocks suitable for dense planting started to be used.
MC is a rootstock moderately growing and has a shallow root system and yielding early.
Fruit is collected in 2nd year following the planting and crop is very productive.
