  abstract = {{P}lant-parasitic nematodes ({PPN}) are the most destructive of all plant pathogens. {T}hey are an economically important group of soil pathogens, causing significant annual damages of up to 25% of world crop production. {M}orocco is considered to be a highly productive country for the colorant/medicinal/spice saffron ({C}rocus sativus {L}.). {T}aliouine and {T}aznakht regions are the most productive areas of this valuable neutraceutical. {D}ue to its metabolic profile, and growth forms, saffron is susceptible to many plant diseases, including plant-parasitic nematodes ({PPN}). {T}his work aims to assess the diversity of {PPN} communities in soils of {T}aliouine and {T}aznakht regions to facilitate understanding of links between their assemblages with biotic and abiotic parameters. {H}erein, nematode communities were characterized in 163 soil samples collected from 11 rural communes characterized by altitudinal gradients in {T}aliouine and {T}aznakht regions. {F}ifteen {PPN} genera belonging to 12 families were identified, among which the four genera {D}itylenchus, {A}phelenchoides, {P}ratylenchus and {H}elicotylenchus, potentiate serious limiting factors in saffron production. {T}heir frequencies are respectively 92, 49, 48 and 36% in the area of {T}aliouine, while in {T}aznakht they represent 95, 69, 33, and 28% respectively. {R}egarding the assessment of diversity at different sites, the genus richness ({R}) index ranges from 2 to 10 distinct genera, whereas the {S}hannon diversity ({H}') index varies from 0.9 to 1.5 and the {E}venness ({E}) index tends to 1. {T}he {C}o-inertia analyses revealed a substantial relationship between nematode communities and soil types. {S}oil texture is the major factor influencing the presence and the abundance of a considerable portion of genera. {M}ultivariate analyses ({MBPLS}) indicated links between humidity, rainfall, minimum temperature and {PPN} taxa, though maximum temperature did not have an impact. {D}itylenchus, {H}elicotylenchus, {P}ratylenchus and {P}aratylenchus were related to the humidity and silt soil that developed in {T}aliouine. {A}phelenchoides, {T}ylenchus, {T}ylenchorynchus and {D}orylaimus were more prevalent in rainy locations and clay soils of {T}aznakht. {S}uitable nematode controlling approaches may be applied and preventative measures should be considered at nursery and field level.},
