“…Therefore, the hazelnut oil can play a significant role in lowering blood cholesterol levels when consumed regularly as part of the diet. As a comparison, the fatty acid compositions of the two kinds of hazelnut oil had similar degrees of unsaturation, however, this profiles was no significant difference with previous reports about American hazelnut oil 3.1 palmitic, 1.6 stearic, 80.6 oleic, and 14.5 linoleic acid 28 and Turkish hazelnut oil 0.03 myristic, 5.58 palmitic, 0.26 palmitoleic, 0.04 heptadecanoic, 0.07 heptadecenoic, 2.47 stearic, 83.85 oleic, 7.35 linoleic, 0.10 linolenic, 0.11 arachidic and 0.14 gadoleic 1 .…”

The lipid contents of two locations of wild hazelnuts were all over 50 , and they were similar to American hazelnut 28 and Turkish hazelnut 1,2 . The contents of crude protein and ash of two locations of wild hazelnuts were similar, meanwhile, there were all higher than American hazelnut 28 and Turkish hazelnut 1,2 .The crude fiber, ash and the crude lipids contents of HN2 were slightly higher than HN1.The differences in different varieties of the same origin and the different origin among the main composition may be due to the local growing condition such as climates and soils 29 .…”

Introduction Hazelnut is one of the four major arboroid nuts in the world. There are about 20 species of hazelnuts, several species of hazelnuts such as C. America, C. avellana and C. colurna were widely cultivated in Asia, Europe and North America. Turkey is the world s leading producer of hazelnuts with a production of 400 000 tones, followed by European Union 145 000 tones , USA 37 200 tones and Azerbaijan 35 000 tones 1. In China, Hazelnut large area of cultivation is less, but there are wild varieties in the northeast and north of the mountains, Varieties are mainly Corylus heterophylla Fisch. and Corylus mandshurica Maxim. The main distribution of Corylus mandshurica Maxim is Hilly mountain in Heilongjiang, Liaoning and Jilin provinces of China. The average single weight and diameter of Corylus mandshurica Maxim is about 0.9 g and 1.37 cm, respectively, which is smaller than other species of hazelnuts. Currently, Hazelnuts are mainly used in the manufacture of food products including candy, chocolate, biscuits and pastries 2. In addition, other widely consumed product from hazelnuts is hazelnut oil 3. Hazelnut oil could be used

“…Due to the high levels of synteny across the genomes described above, direct use of Illumina sequence data to infer variable degrees of interspecific hybridization, using tools such as sppIDer (Langdon et al, 2018), is limited. Biallelic SNPs were, therefore, identified using the TASSEL GBSv2 pipeline (Bradbury et al, 2007) and filtered for missing data (<10% across all samples), minor allele frequency (>0.05), linkage disequilibrium (r 2 < 0.75) and allele depth (80% of samples with a depth >8) using bcftools (Danecek et al, 2021). Population structure analysis using principal components analysis (Price et al, 2006) has been shown to be a simple and efficient alternative to more complex modelbased approaches such as STRUCTURE (Falush et al, 2007) and ADMIXTURE (Alexander et al, 2009).…”

SummaryThe native, perennial shrub American hazelnut (Corylus americana) is cultivated in the Midwestern United States for its significant ecological benefits, as well as its high‐value nut crop. Implementation of modern breeding methods and quantitative genetic analyses of C. americana requires high‐quality reference genomes, a resource that is currently lacking. We therefore developed the first chromosome‐scale assemblies for this species using the accessions ‘Rush’ and ‘Winkler’. Genomes were assembled using HiFi PacBio reads and Arima Hi‐C data, and Oxford Nanopore reads and a high‐density genetic map were used to perform error correction. N50 scores are 31.9 Mb and 35.3 Mb, with 90.2% and 97.1% of the total genome assembled into the 11 pseudomolecules, for ‘Rush’ and ‘Winkler’, respectively. Gene prediction was performed using custom RNAseq libraries and protein homology data. ‘Rush’ has a BUSCO score of 99.0 for its assembly and 99.0 for its annotation, while ‘Winkler’ had corresponding scores of 96.9 and 96.5, indicating high‐quality assemblies. These two independent assemblies enable unbiased assessment of structural variation within C. americana, as well as patterns of syntenic relationships across the Corylus genus. Furthermore, we identified high‐density SNP marker sets from genotyping‐by‐sequencing data using 1343 C. americana, C. avellana and C. americana × C. avellana hybrids, in order to assess population structure in natural and breeding populations. Finally, the transcriptomes of these assemblies, as well as several other recently published Corylus genomes, were utilized to perform phylogenetic analysis of sporophytic self‐incompatibility (SSI) in hazelnut, providing evidence of unique molecular pathways governing self‐incompatibility in Corylus.

“…As a woody perennial crop, hazelnuts have substantial potential to provide ecosystem services such as reduced soil erosion and nutrient runoff (Demchik et al, 2014), while also sequestering carbon in above and belowground biomass (Granata et al, 2020). Expanding the climatic conditions under which commercially viable hazelnut varieties can be grown would not only make production more resilient in the face of changing climates, but provide high-value alternative crops to producers across wider geographies.…”

The native shrub American hazelnut (Corylus americana) is currently used in breeding programs that are aiming to develop commercially viable hazelnut varieties for the U.S. Upper Midwestern U.S. This species provides significant ecological benefits as it is a perennial crop and well-adapted to this region. Breeding cycles for perennial species are long, and may benefit from the use of predictive methods such as genomic selection to reduce cycle time and increase the efficiency of field trials. High-quality reference genome assemblies are very useful for the implementation marker-assisted selection and genomic prediction, and we therefore developed the first chromosome-scale reference assemblies for C. americana, using the accessions 'Rush' and 'Winkler'. Initial draft assemblies were created using HiFi PacBio reads and Arima Hi-C sequencing to assemble genomes into 11 pseudomolecules. We then utilized Oxford Nanopore reads and a high-density genetic map in order to perform error correction. N50 scores were calculated to be 31.9 Mb and 35.3 Mb for 'Rush' and 'Winkler', respectively, while 97.1% (for 'Winkler') and 90.2% (for 'Rush') of the total genome was assembled into the 11 pseudomolecules. Gene prediction was performed using both RNAseq libraries as well as protein homology data. 'Rush' had a BUSCO score of 99.0 for its assembly and 99.0 for its annotation, while 'Winkler' had corresponding scores of 96.9 and 96.5, indicating extremely high-quality assemblies. These two independent, de novo assemblies enable unbiased assessment of structural variation across the genome, as well as patterns of syntenic relationships within C. americana and the Corylus genus. These assemblies are also an important first step in providing a resource for using next-generation sequencing data in the improvement of C. americana. We demonstrate this utility through the generation of high-density SNP marker sets from genotyping-by-sequencing data for 1,343 C. americana, C. avellana, and C. americana x C. avellana hybrids, in order to assess population structure in natural and breeding populations. Finally, the transcriptomes of these assemblies, as well as several other recently published Corylus genomes, were utilized to perform phylogenetic analysis of sporophytic self-incompatibility (SSI) in hazelnut, providing further evidence of unique molecular pathways governing self-incompatibility in Corylus not exhibited in other well-studied SSI systems. We hope these assemblies will aide in the application of modern breeding methods to the development of commercially viable hazelnut varieties for the U.S. Upper Midwest.
