  abstract = {{T}he endemic palm from the {C}anary {I}slands, {P}hoenix canariensis, is one of the most distinctive elements of the {C}anarian vegetation landscape, contributing to cultural, economic and environmental aspects. {O}ne of the main conservation problems facing this iconic palm is anthropogenic hybridization with other {P}hoenix species, particularly {P}hoenix dactylifera, which has been introduced extensively throughout its geographical range. {T}herefore, it is important to obtain a genetic tool that addresses different issues that may have an impact on the protection of {P}. canariensis, including ornamental applications and wild population conservation purposes. {O}ur main goals were to detect a molecular tracer that could reliably distinguish between {P}hoenix canariensis and {P}. dactylifera in the {C}anary archipelago and to characterize the presence and extent of genetic hybridization events between the two species. {W}e used 19 nuclear microsatellites and 1 chloroplast minisatellite set and analysed a large sample size ({N} = 433) of plants using both {B}ayesian methods and ordination techniques. {O}ur data showed that a set of 13 nuclear markers revealed diagnostic alleles for {P}. canariensis, which were defined as the {C}anarian nuclear genotype ({CNG}). {M}oreover, {P}. canariensis exhibited an exclusive chlorotype of 266 bp that together with the {GNC} serve as an indicator of genetic purity in the {C}anarian palm. {T}hese markers are sufficient to detect any hybrid, even if it is not related to morphological differences. {T}he occurrence of a considerable number of specimens with different degrees of hybridization is discussed in terms of the existence of different generations of hybrids and different types of crosses. {T}hus, the genetic tracers represent an invaluable tool to address any proposal for the genetic conservation of {P}hoenix canariensis.},
