Abstract

A pear rootstock breeding program was initiated at INRA, Angers, France in 1998 in collaboration with IRTA of Spain in order to select a pear rootstock adapted to cultivation in Mediterranean countries.
The programs goals were to develop genotypes showing high tolerance to iron chlorosis as well as tolerance to variation in water supply linked with good ability to propagate and be graft-compatible.
Crosses were made between the new INRA pear rootstock selection Pyriam and four Mediterranean Pyrus species: Pyrus communis cordata hybrid, P. amygdaliformis, P. amygdaliformis persica, and P. elaeagrifolia. Progenies of each cross were split into two groups.
The first group was selected in France for the ability to root, a straight growth habit and compatibility with Williams pear.
The second group was selected in Spain for the tolerance to iron chlorosis, low vigor and compatibility with Conference pear. P. communis cordata, P. amygdaliformis persica and P. elaeagrifolia offspring developed less leaf chlorosis, whereas Williams offspring had low vigor in comparison with the interspecific cross.
If low vigor and chlorotic adaptation were combined, all interspecific crosses and Williams offspring had a similar selection percentage of around 18% offspring without chlorotic symptoms and a vigor lower than 50% of BA 29 rootstock.
Among the crosses, P. communis cordata, P. amygdaliformis persica and Williams offspring had a slightly better selection percentage.
