The interference color of Akoya pearls from Pinctada fucata is one of the important factors which determine their quality. Interference color is determined by pearl crystal thickness of the aragonite layer. We established two oyster lines by selective breeding of donor oysters with average shell crystal thicknesses of 300 and 360 nm, respectively. A pallial piece of mantle tissue from the donor oysters and a nucleus were grafted into the gonad of recipient oysters (n=383) and cultured for 15 months. Pearl crystal thickness in recipient shells was correlated with the nacreous crystal thickness of the donor shell at all time points between 7 and 15 months after grafting (p <0.010.05). Although the relationship was weak, it is suggested that the recipient shell crystal thickness was also correlated with the crystal thickness of the pearl. Additionally, the shell crystal thickness was negatively correlated with growth. These results suggest that the interference color of pearls can be improved by selective breeding of donor oysters.
