The postharvest quality of 3 strains (Naga-fu 2, 6 and 12) of Fuji apples from 2 growing locations (Washington and Oregon) was evaluated over 4 storage seasons. Fruit quality was determined at harvest, after 90 days of regular atmosphere (RA) storage and after 210 days of controlled atmosphere (CA) storage at 1% O2 + 1% CO2, 1% O2 + 3% CO2 and 1% O2 + 5% CO2. Strains of Fuji apples had very little influence on quality at harvest or after RA storage. After CA storage some quality differences were evident between strains, particularly, for red colour development, which was greater in Naga-fu 2. Growing location had an influence on quality parameters of Fuji apples at harvest and after storage. These quality differences determined for Fuji apples between growing locations may offer an explanation of the differences reported for Fuji apple quality of the same strain. Carbon dioxide level in the storage atmosphere had a direct influence on fruit quality. Fruits stored at 5% CO2 displayed more interna

l breakdown at cavity development and less scald development than fruits stored at 1% and 3% CO2. Fuji apples stored well and maintained good quality at 3% CO2, which would be less costly to maintain than 1% CO2, the standard recommendation for the CA storage of Fuji apples.
