To expand the gene pool and introduce new traits to the tetraploid cultivars of Vaccinium corymbosum from wild diploid species V. This work contributes to genetic variation data and provides important insights into the phytochemical properties of cultivated lingonberries, which can be useful for choosing and developing lingonberry genomes for commercial cultivation and targeted application. Multivariate data analysis clustered the investigated samples into distinct groups, which differed by their country of origin. ![]() An abundance of identified compounds was determined in lingonberry raw materials of cultivars ‘Kostromička’, ‘Kostromskaja rozovaja’, ‘Rubin’, and V. In general, leaves of cultivars were richer in the content of most phenolics, while fruits stood out with their higher content of triterpenoids. Results showed that phytochemical profiles were significantly different among lingonberry cultivars and intraspecific taxa based on the levels of individual phytoconstituents and their distribution throughout lingonberry parts. ![]() Fifty-nine specialized metabolites, belonging to subgroups of phenolics and triterpenoids, were identified and quantified using validated chromatographic methods. The present study aimed to distinguish between ten selected cultivars, one variety, and one subspecies of lingonberry raw materials. Cultivation of this horticultural crop however is still in its infancy with a small commercial industry established. Leaves and fruits of lingonberries (Vaccinium vitis-idaea L.) are important raw materials for the food and health care industries, gaining notoriety as “superfoods”. Altogether, the present study provides new resources that can be used to breed for desirable traits in lingonberry. The identified candidate genes containing the SNPs need further studies on their potential role in local adaptation of lingonberry. This resource might prove useful in high-density quantitative trait locus analysis, and association mapping. The putative SNPs discovered are the first genomic resource for lingonberry. To obtain insights on the function of the genomic sequences containing the SNPs likely to be associated with the environmental or phenotypic variables, we performed a sequence-based functional annotation and identified homologous protein-coding sequences with functional roles related to abiotic stress response, pathogen defense, RNA metabolism, and, most interestingly, phenolic compound biosynthesis. We found 132 SNPs likely associated with at least one of the environmental or phenotypic variables. ![]() We identified 1586 high-quality putative SNPs using the UNEAK pipeline available in TASSEL. We also searched for an association between the identified SNPs and two phenotypic traits: the total phenolic content (TPC) and antioxidant capacity (AC) of fruit. To elucidate a potential adaptation to environmental conditions we searched for genotype-environment associations by applying three distinct approaches to screen the identified single nucleotide polymorphisms (SNPs) for correlation with six environmental variables. We used Genotyping-by-Sequencing (GBS) to analyze the genetic variation of 56 lingonberry samples from across Newfoundland and Labrador, Canada. However, no genomic resources are available for this species. Genetic markers can facilitate the selection of berries with desirable climatic adaptations, agronomic and nutritious characteristics to improve cultivation programs. Lingonberry (Vaccinium vitis-idaea L.), one of the least studied fruit crops in the Ericaceae family, has a dramatically increased worldwide demand due to its numerous health benefits. ![]()
