Table 1 Genetic parameters of 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). Diagonals are estimated narrow-sense heritability and off-diagonals are genetic correlations. Significant (p < 0.0001) correlations are marked with*.
