“…Moreover, the null alleles generated using SSR markers may also be attributable to the positive value of F IS [44]. The overall F ST value in our study (from 0.0068 to 0.3063) indicated significant differentiation among provenances, which is comparable with data for S. purpurea (from 0.064 to 0.420) [23] and S. arbutifolia (from 0.01 to 0.41) [29], but much higher than that reported for S. viminalis (from 0.040 to 0.119) [21], S. psammophila (from 0.008 to 0.016) [22], S. alba (F ST = 0.07) [25], and several Populus species [44]. As described by Wright [46], F ST > 0.25 represents an enormous genetic differentiation, 0.25 > F ST > 0.15 indicates a comparatively large genetic differentiation, 0.15 > F ST > 0.05 shows a moderate genetic differentiation, and F ST < 0.05 is negligible.…”

Chosenia arbutifolia (Pall.) A. Skv. is a unique and endangered species belonging to the Salicaceae family. It has great potential for ornamental and industrial use. However, human interference has led to a decrease in and fragmentation of its natural populations in the past two decades. To effectively evaluate, utilize, and conserve available resources, the genetic diversity and population structure of C. arbutifolia were analyzed in this study. A total of 142 individuals from ten provenances were sampled and sequenced. Moderate diversity was detected among these, with a mean expected heterozygosity and Shannon’s Wiener index of 0.3505 and 0.5258, respectively. The inbreeding coefficient was negative, indicating a significant excess of heterozygotes. The fixation index varied from 0.0068 to 0.3063, showing a varied genetic differentiation between populations. Analysis of molecular variance demonstrated that differentiation accounted for 82.23% of the total variation among individuals, while the remaining 17.77% variation was between populations. Furthermore, the results of population structure analysis indicated that the 142 individuals originated from three primitive groups. To provide genetic information and help design conservation and management strategies, landscape genomics analysis was performed by investigating loci associated with environmental variables. Eighteen SNP markers were associated with altitude and annual average temperature, of which five were ascribed with specific functions. In conclusion, the current study furthers the understanding of C. arbutifolia genetic architecture and provides insights for germplasm protection.

“…The "epitype" LE 01065618 was collected in Turkey. Salix alba is common in Turkey (Skvortsov & Edmondson, 1982;Degirmenci & al., 2019;Marchenko, 2019), which also supports our above conclusion that the specimen annotated as the "epitype" of S. euxina belongs to S. alba. Belyaeva's (2009) statement about the origin of S. fragilis in Asia Minor is doubtful; we analyzed the cited specimens of the pure S. fragilis from that region (Skvortsov, 1973;Skvortsov & Edmondson, 1982) and reported that the identification of none of them can be confirmed (Table 3) (Marchenko & Kuzovkina, 2020b).…”

We evaluated the recent replacements of Salix fragilis L. with S. еuxina I.V.Belyaeva, and S. ×rubens Schrank with S. ×fragilis L. (S. alba L. × S. euxina). The specimens of S. еuxina, identified by Belyaeva, were analyzed. The morphological characters did not coincide with those in the species description, and the ovule number was different in all specimens. This makes the application of the name S. еuxina impossible and precludes the possibility of replacing S. fragilis for S. euxina. Also, the original Linnaean descriptions of S. fragilis, the related S. alba, and S. pentandra, as well as Linnaeus's herbarium specimens, were examined. Each of the three protologues describes the characteristics of the pure species as well as their hybrids: S. pentandra × S. fragilis (in the protologues of S. pentandra and S. fragilis) and S. alba × S. fragilis (in the protologue of S. alba). Our study of the morphology, geographic data, and ovule number demonstrates that the recent replacements of S. fragilis with S. еuxina, and S. ×rubens with S. ×fragilis (S. alba × S. euxina) were erroneous. We propose continuing to use S. fragilis as the name for a glabrous crack willow and S. ×rubens for its hybrid with S. alba.

“…The large population was crossed between two S. viminalis × (S. viminalis × S. schwerinii) hybrid by using AFLP and SNPs (Hanley et al, 2006). In Turkey the microsatellite markers (SSR) were used to determine the genetic variation of Salix alba (Değirmenci et al, 2019). Molecular breeding tools are important to provide powerful approaches for gene discovery, however, genetic linkage maps with technology of mapping of QTL have greater impact on bioenergy (Brunner et al, 2007).…”

Salix L. species are economically excellent candidates for sustainable bioenergy production. Especially, shrubs of Salix L. are used in agroforestry for their characteristics of quick growth, wide distribution and resistance to disease and stress. The shrubs of subgenera Salix and Vetrix under Salix L. commonly found in riparian or wetland habitats of Turkey have great potential as bioenergy crops with high biomass yield. This review study will provide information to determine the potential of willows species native to Turkey for bioenergy and to contribute to energy production by using the biomass of fast-growing shrub willows as renewable energy resources. Firstly, botanical description, habitat, growth, traditional breeding efforts and genetic composition were summarized concerning about the bioenergy potential of willows from results of existing studies. Secondly, the titles, establishing willow plantations, biomass reducing the greenhouse gas emissions responsible for climate change and development of willow as bioenergy crop in worldwide and Turkey were reviewed. Lastly, the future of bioenergy potential estimation of willows was proposed to provide some instructions for bioenergy development in Turkey.
