摘 要：Eremurus species,better known as‘Foxtail Lily’or‘Desert Candle’,are important worldwide in landscaping and the cutflower *** of the centers of highest diversity of the genus Eremurus is Iran,which has seven ***,little is known about the genetic diversity within the genus *** the advent of genotyping-bysequencing(GBS),it is possible to develop and employ single nucleotide polymorphism(SNP)markers in a costefficient manner in any species,regardless of its ploidy level,genome size or availability of a reference *** structure and phylogeographic analyses of the genus Eremurus in Iran using a minimum of 3002 SNP markers identified either at the genus level or at the species level from GBS data showed longitudinal geographic structuring at the country scale for the genus and for the species *** and ***,and at the regional scale for *** analyses furthermore showed a close genetic relatedness between *** and *** to the extent that they should be considered subspecies within an ***/stenophyllus species *** close genetic relatedness may explain why crosses between these two(sub)species have been found in the wild and are exploited extensively as ***,current species identification,while robust,relies on flower morphology.A subset of seven SNPs with species-specific(private)alleles were selected that differentiate the seven Eremurus *** markers will be especially useful for cultivar protection and in hybrid production,where true hybrids could be identified at the seedling stage.
