  abstract = {{T}he development of cultivars resistant to coffee leaf rust caused by the fungal pathogen {H}emileia vastatrix is a priority in coffee breeding. {H}owever, only very few descendants of interspecific hybrids between {C}offea arabica and diploid relative species have been used as resistance source. {I}dentification of new sources of resistance appeared therefore particularly worthwhile. {H}ybrid plants derived from interspecific hybridization between {C}. arabica and {C}offea canephora and found in neo-natural coffee tree populations of {N}ew {C}aledonia were therefore investigated. {A}mplified {F}ragment {L}ength {P}olymorphism and micro-satellites amplification were used to evaluate the genetic diversity of 14 hybrid plants, and rust resistance was evaluated by inoculation with a panel of rust races representing a large variability in virulence. {A}n important genetic diversity was characterized in hybrid plants originating from introgressions into {C}. arabica from various {C}. canephora progenitors. {O}n the 14 plants tested for leaf rust resistance, eight appeared resistant to all races investigated. {S}uch plant material should represent a highly valuable resource for {C}. arabica breeding against coffee leaf rust.},
