  abstract = {{T}he genetic diversity of the date palm wilt pathogen #{F}usarium oxysporum$ f. sp. #albedinis$ in {A}lgeria was assessed using vegetative compatibility, restriction fragment length polymorphism ({RFLP}) of mitochondrial {DNA} (mt{DNA}), and random amplified polymorphic {DNA} ({RAPD}). {N}inety-eight isolates were collected from the main infested regions, {T}ouat, {G}ourara and {M}zab, and 6 isolates from {M}orocco were added for comparison. {A}ll isolates were vegetatively compatible and belonged to {VCG} 0170. {N}o variation was detected in the mt{DNA} of a subset of 73 isolates and the {RAPD} analysis indicated that they were genetically very closely related. {H}owever, some geographic substructuring was apparent, suggesting that local diversification of the pathogen might have occurred. {T}hese results provide evidence that the {A}lgerian isolates of #{F}. oxysporum$ s. sp. #albedinis$ belong to a same clonal lineage and support the hypothesis that they were probably founded by a single virulent clone that originated from the {M}oroccan oases where the date palm wilt ({B}ayoud disease) was first detected. {B}ased on similarity of {RAPD} patterns occurring in different oases, and on historical records of the {B}ayoud disease in {A}lgeria, spread of the pathogen in the different regions is discussed.
