Of the genus Pyrus communis for pear trees
General information
Obtained by
Dipartimento di Colture Arboree dell’Università di Bologna (Italy)
Species
Pear tree, Pyrus communis
Origin
Selections resulting from the open pollination of the varieties 'Volpina' x 'Mora'.
Agronomic Characteristics
Vigour
Vigor equal to or slightly greater than quince Provence BA-29.
Compatibility
Perfect compatibility with all varieties of the Pyrus genus. Ideal for medium-vigor varieties with compatibility issues like ‘Limonera’ or ‘Williams.’
Root System
Broad exploration capacity, abundant fine roots, optimal anchorage—no support structure needed.
Suckers
Not prone to producing suckers.
Plantation Suitability
Suitable for medium-density plantations.
Fruit Size
Fruit size equal to or slightly less than BA-29, depending on the crop load.
Soil Adaptation
Good adaptation to calcareous soils.
Water Sensitivity
Sensitive to waterlogging, like all seedling rootstocks.
Based on the information presented in the FOX 9 catalog and the available results from both experimental and commercial farms in Italy and Spain, it can be concluded that the Fox 9 rootstock is an interesting option for the future of pear cultivation in warm areas such as the Ebro Valley, Murcia Region, or Extremadura. Specifically for the varieties 'Limonera', 'Williams', 'Abate Fetel', and 'Conference'.
This is due to its good adaptability to Mediterranean climates and calcareous soils with high pH. It induces medium vigor, with a balanced tree of optimal fruiting and good production, being a Pyrus. The in vitro clonal propagation ensures perfect homogeneity of the plantation and guaranteed sanitary status.
