Abstract

Fruit size and shape are important external quality traits in commercial crops. To determine the genetic relationshipbetweenthe size andshape of apple fruits, quantitative traitloci(QTLs)for apple size (average weight), length, diameter, and shape (length/diameter ratio) were identified and mapped in progeny of a ‘Jonathan’ × ‘Golden Delicious’ cross. Fruit size, length, and diameter followed a normal distribution. There was no correlation between apple size and shape, but both variables were significantly correlated with length and diameter. Forty-five QTLs for apple size, length, diameter, and shape were mapped to 13 chromosomes ofthe twoparent cultivars. Ofthese, 12 QTLs for fruitlengthanddiameter either overlapped or were closely associated with QTLs for fruit size, whereas three co-localized with QTLs for fruit shape. No QTLs for fruit size mapped to the same or neighboring regions as QTLs for fruit shape, suggesting that size and shape are under independent genetic control.
