摘 要：Many fruit quality traits in apple(Malus domestica Borkh.)are controlled by multiple small-effect quantitative trait loci(QTLs).Genomewide selection(genomic selection)might be an effective breeding approach for highly quantitative traits in woody perennial crops with long generation times like *** goal of this study was to determine if genomewide prediction is an effective breeding approach for fruit quality traits in an apple scion breeding *** apple scion breeding germplasm(nindividuals=955),high-quality single nucleotide polymorphism(SNP)data(nSNPs=977),and breeding program fruit quality trait data at harvest were *** parents‘Honeycrisp’and‘Minneiska’were highly *** to high predictive abilities were observed for most fruit quality traits at *** example,when 25%random subsets of the germplasm set were used as training sets,mean predictive abilities ranged from 0.35 to 0.54 across ***,training and test sets,family size for within family prediction,and number of SNPs per chromosome affected model predictive *** of large-effect QTLs as fixed effects resulted in higher predictive abilities for some traits(*** red overcolor).Postdiction(***)analyses demonstrated the impact of culling threshold on selection *** results of this study demonstrate that genomewide selection is a useful breeding approach for certain fruit quality traits in apple.
