“…Later studies laid the evidence of the population structure of peach to be exploited facilitating the genome-wide similarity and relationship studies. Lim et al (2016) conducted a study using 5SSR markers that are highly polymorphic in nature, to report the genetic diversity among 160 strawberry accessions. They discovered 60 distinct alleles, with allele frequencies ranging from 0.006 to 1 and similarity ratings ranging from 0.034 to 0.963 (average: 0.507).…”

Genetic improvement of temperate fruit and nut crops through conventional breeding methods is not sufficient alone due to its extreme time-consuming, cost-intensive, and hard-to-handle approach. Again, few other constraints that are associated with these species, viz., their long juvenile period, high heterozygosity, sterility, presence of sexual incompatibility, polyploidy, etc., make their selection and improvement process more complicated. Therefore, to promote precise and accurate selection of plants based on their genotypes, supplement of advanced biotechnological tools, viz., molecular marker approaches along with traditional breeding methods, is highly required in these species. Different markers, especially the molecular ones, enable direct selection of genomic regions governing the trait of interest such as high quality, yield, and resistance to abiotic and biotic stresses instead of the trait itself, thus saving the overall time and space and helping screen fruit quality and other related desired traits at early stages. The availability of molecular markers like SNP (single-nucleotide polymorphism), DArT (Diversity Arrays Technology) markers, and dense molecular genetic maps in crop plants, including fruit and nut crops, led to a revelation of facts from genetic markers, thus assisting in precise line selection. This review highlighted several aspects of the molecular marker approach that opens up tremendous possibilities to reveal valuable information about genetic diversity and phylogeny to boost the efficacy of selection in temperate fruit crops through genome sequencing and thus cultivar improvement with respect to adaptability and biotic and abiotic stress resistance in temperate fruit and nut species.

“…Moreover, it has been reported that genomic selection could contribute significant improvement for yield and biomass of fruits ( Gezan et al., 2017 ). To identify the QTLs, DNA markers, such as simple sequence repeats (SSR) and single nucleotide polymorphism (SNP), have been used ( Lim et al., 2017 ; Verma et al., 2017 ; Nagamatsu et al., 2021 ; Fan et al., 2022 ). In particular, several metabolic studies to targeting specific strawberry VOCs, such as mesifurane and γ-decalactone, have facilitated enhancing strawberry quality with improved aromatic profiles ( Zorrilla-Fontanesi et al., 2012 ; Oh et al., 2021 ).…”

IntroductionThe strawberry industry in South Korea has witnessed a significant 65% growth over the past decade, surpassing other fruits and vegetables in production value. While sweetness and acidity are well-recognized flavor determinants, the role of volatile organic compounds (VOCs) in defining the desirable flavor profiles of strawberries is also crucial. However, existing research has predominantly concentrated on a limited range of commercial cultivars, neglecting the broader spectrum of strawberry varieties.MethodsThis study embarked on developing a comprehensive VOC database for a diverse array of strawberry cultivars sourced both domestically and internationally. A total of 61 different strawberry cultivars from Korea (45), the USA (7), Japan (8), and France (1) were analyzed for their VOC content using Tenax TA Thermo Desorption tubes and Gas Chromatography-Mass Spectrometry (GC-MS). In addition to VOC profiling, heritability was assessed using one-way ANOVA to compare means among multiple groups, providing insights into the genetic basis of flavor differences.Results and discussionThe analysis identified 122 compounds categorized into esters, alcohols, terpenes, and lactones, with esters constituting the majority (46.5%) of total VOCs in Korean cultivars. ‘Arihyang’, ‘Sunnyberry’, and ‘Kingsberry’ exhibited the highest diversity of VOCs detected (97 types), whereas ‘Seolhong’ showed the highest overall concentration (57.5mg·kg-1 FW). Compared to the USA cultivars, which were abundant in γ-decalactone (a peach-like fruity aroma), most domestic cultivars lacked this compound. Notably, ‘Misohyang’ displayed a high γ-decalactone content, highlighting its potential as breeding germplasm to improve flavor in Korean strawberries. The findings underscore the importance of a comprehensive VOC analysis across different strawberry cultivars to understand flavor composition. The significant variation in VOC content among the cultivars examined opens avenues for targeted breeding strategies. By leveraging the distinct VOC profiles, particularly the presence of γ-decalactone, breeders can develop new strawberry varieties with enhanced flavor profiles, catering to consumer preferences for both domestic and international markets.

“…There have been several attempts to differentiate strawberry cultivars at the DNA level using various molecular markers. Reported methods include randomly amplified polymorphic DNA (RAPD) markers [7,[10][11][12], amplified fragment length polymorphism (AFLP) markers [13][14][15], cleavage amplified polymorphisms (CAPS) [9], simple sequence repeats (SSR) [16,17], and combinations of these markers [18][19][20]. A more recent molecular method of cultivar discrimination is the use of single nucleotide polymorphism (SNP) markers.…”

BACKGROUND: Commercial strawberry production in the Philippines is done by smallholder farmers in La Trinidad, Benguet, where the climate is conducive for optimal growth of this temperate crop. However, these farmers are not cognizant of the importance of proper cultivar identification, particularly during runner propagation, distribution, and transplanting.Thus, there is a high likelihood that misidentification of commonly grown cultivars has taken place. OBJECTIVE:The study aimed to develop single nucleotide polymorphism markers and use them to detect possible misidentification among strawberry cultivars. METHODS:Leaf samples from several cultivars were obtained from farmers and the germplasm collection of a local university in La Trinidad, Benguet, Philippines. Expressed sequence tags from the ANR gene were screened for putative SNPs. Eleven SNP markers were developed and used to discriminate among the collected samples. RESULTS:The SNP markers grouped the cultivars into five genotypic clusters with seven distinct genotypic identities. Clustering analysis revealed inconsistencies between the farmers' identification and the molecular classification. 'Sweet Charlie' samples were assigned to four genotypic clusters and 'Strawberry Festival' samples were grouped into three separate clusters. CONCLUSION:There is a high probability that cultivar misidentification has indeed occurred. The molecular markers developed in this study could assist in future cultivar verification efforts, germplasm management, and breeding programs.
