| 1 | Validation of SNP markers for fruit quality and disease resistance loci in apple (Malus × domestica Borkh.) using the OpenArray® platform显示文摘Genome mapping has promised much to tree fruit breeding during the last 10 years.Nevertheless,one of the greatest challenges remaining to tree fruit geneticists is the translation of trait loci and whole genome sequences into diagnostic genetic markers that are efficient and cost-effective for use by breeders,who must select genetically optimal parents and subsequently select genetically superior individuals among their progeny.To take this translational step,we designed the apple International RosBREED SNP Consortium OpenArray v1.0(IRSCOA v1.0)assay using a set of 128 apple single nucleotide polymorphisms(SNPs)linked to fruit quality and pest and disease resistance trait loci.The Thermo Fisher Scientific OpenArray®technology enables multiplexed screening of SNP markers using a real-time PCR instrument with fluorescent probe-based Taqman®assays.We validated the apple IRSCOA v1.0 multitrait assay by screening 240 phenotyped individuals from the Plant&Food Research apple cultivar breeding programme.This set of individuals comprised commercial and heritage cultivars,elite selections,and families segregating for traits of importance to breeders.In total,33 SNP markers of the IRSCOA v1.0 were validated for use in marker-assisted selection(MAS)for the scab resistances Rvi2/Vh2,Rvi4/Vh4,Rvi6/Vf,fire blight resistance MR5/RLP1,powdery mildew resistance Pl2,fruit firmness,skin colour,flavour intensity,and acidity.The availability of this set of validated trait-associated SNP markers,which can be used individually on multiple genotyping platforms available to various apple breeding programmes or re-designed using the flanking sequences,represents a large translational genetics step from genomics to crop improvement of apple. | David Chagné Stijn Vanderzande Chris Kirk Natalie Profitt Rosemary Weskett Susan E.Gardiner Cameron P.Peace Richard K.Volz Nahla V.Bassil | 2019 | Horticulture Research2019，6，1： | 3 |
