Table 2.
Single nucleotide polymorphism (SNP) with the largest effect (phenotypic variance explained by the SNP; R2) on various pear fruit quality traits (firmness: FIRM; crispness: CRIS; juiciness: JUIC; sweetness: SWET; sourness: SOUR; flavour intensity: FINT; fruit scuffing: SCUF; shape: SHAP; russet: RUSS; fruit weight: AVFW). The allele substitution effect (ASE), measured in phenotypic standard deviation units, of the largest-effect SNP is also presented. Statistical significance of SNP effect is shown using −log10p values.
