Peach was domesticated in China more than four millennia ago and from there it spread world-wide. Since the middle of last century, peach breeding programs have been very dynamic generating hundreds new commercial varieties, however, most cases such varieties derive a limited collection parental lines (founders). This is one reason for observed low levels variability gene pool, implying that knowledge extent distribution genetic critical to allow choice adequate parents confer enhanced...
Maturity date (MD) is a crucial factor for marketing of fresh fruit, especially those with limited shelf-life such as peach (Prunus persica L. Batsch): selection several cultivars differing MD would be advantageous to cover and extend the season. Aims this work were fine mapping identification candidate genes major maturity locus previously identified on linkage group 4. To improve genetic resolution target two F2 populations derived from crosses Contender x Ambra (CxA, 306 individuals)...
High-quality genotypic data is a requirement for many genetic analyses. For any crop, errors in genotype calls, phasing of markers, linkage maps, pedigree records, and unnoticed variation ploidy levels can lead to spurious marker-locus-trait associations incorrect origin assignment alleles individuals. High-throughput genotyping requires automated scoring, as manual inspection thousands scored loci too time-consuming. However, SNP scoring result that should be corrected ensure recorded are...
Highly polygenic traits such as fruit weight, sugar content and acidity strongly influence the agroeconomic value of peach varieties. Genomic Selection (GS) can accelerate yield quality gain if predictions show higher levels accuracy compared to phenotypic selection. The available IPSC 9K SNP array V1 allows standardized highly reliable genotyping, preparing ground for GS in peach. A repeatability model (multiple records per individual plant) genome-enabled eleven European populations is...
Double flowers with supernumerary petals have been selected by humans for their attractive appearance and commercial value in several ornamental plants, including Prunus persica (peach), a recognized model Rosaceae genetics genomics. Despite the relevance of this trait, knowledge underlying genes is limited. Of two distinct loci controlling double-flower phenotype peach, we focused on dominant Di2 locus. High-resolution linkage mapping five segregating progenies delimited to an interval...
Fruit quality traits have a significant effect on consumer acceptance and subsequently peach (Prunus persica (L.) Batsch) consumption. Determining the genetic bases of key fruit is essential for industry to improve increase Pedigree-based analysis across multiple pedigrees can identify genomic basis complex direct implementation in marker-assisted selection. This strategy provides breeders with better-informed decisions improves selection efficiency and, subsequently, saves resources time.
Peach is one of the most important fruit crops in world, with global annual production about 24.6 million tons. The United States fourth-largest producer after China, Spain, and Italy. consumption has decreased over last decade, likely due to inconsistent quality on market. Thus, marker-assisted selection for traits highly desired fresh market peach breeding programs major goals RosBREED project. ability use DNA information select desirable would enable breeders efficiently plan crosses...
Brown rot, caused by Monilinia spp., is one of the most important diseases on stone fruit worldwide. Severe yield loss can be pre- and post-harvest decay. Although some degree tolerance has been reported in peach almond, genetic resistance cultivars still lacking. To date, only few genomic regions associated with brown rot response skin flesh have detected peach. Previous studies suggested being a polygenic quantitative trait. More information needed to uncover genetics behind identify this...
Abstract Genomic regions associated with ripening time (RPT) and soluble solids concentration (SSC) were mapped using a pedigreed population including multiple F 1 2 families from the Clemson University peach breeding program (CUPBP). RPT SSC QTLs consistently identified in two seasons (2011 2012) average datasets (average of seasons). A target region spanning 10,981,971–11,298,736 bp on chromosome 4 reference genome used for haplotype analysis revealed four haplotypes significant...
Highly saturated genetic linkage maps are extremely helpful to breeders and an essential prerequisite for many biological applications such as the identification of marker-trait associations, mapping quantitative trait loci (QTL), candidate gene identification, development molecular markers marker-assisted selection (MAS) comparative studies. Several high-density maps, constructed using 9K SNP peach array, available peach. However, each these is based on a single population has limited use...
Abstract In peach, a long peduncle can help minimize mechanical damages/physical injuries in the fruit at harvest and also be useful postharvest handling transportation. view of genetically dissecting length (PL) we have performed Quantitative Trait Locus (QTL) mapping study for PL using F 2 progeny 117 individuals from cross ‘PI 91459 [NJ Weeping]’ x ‘Bounty’ (WxBy). The was phenotyped three years (2011, 2012 2014) QTL analysis four methods: Kruskall-Wallis, Interval Mapping, Multiple...
Abstract Background Environmental adaptation and expanding harvest seasons are primary goals of most peach [ Prunus persica (L.) Batsch] breeding programs. Breeding perennial crops is a challenging task due to their long cycles large tree size. Pedigree-based analysis using pedigreed families followed by haplotype construction creates platform for QTL marker identification, validation, the use marker-assisted selection in Results Phenotypic data seven F 1 low medium chill full-sib were...
Understanding the relationship between composition and taste is of pivotal importance for fruit quality improvement. This study aims to shed a light on complex apricot (both flesh skin) sensory perception. For this purpose, total 23 cultivars breeding selections were characterized range fruit-quality-related traits (maturity date, fresh weight, firmness, soluble solids content, titratable acidity polyphenols content) ten organic acids pattern in both skin. Fruit analytical data correlated...

Brown rot, caused by <i>Monilinia</i> spp., is one of the most important postharvest diseases stone fruits worldwide. rot resistance in peach a polygenic trait controlled multiple genes with small effect. In this study, we assessed feasibility genomic prediction (GP) for brown using eight contrasting methods (GBLUP, rrBLUP, BayesA, BayesB, BayesC, Bayesian Ridge Regression, Lasso and RKHS). A testing panel 38 cultivars/advanced selections 288 F<sub>1</sub> individuals from 27...
