The study was conducted to evaluate the change of qualities of newly bred cultivar ‘Hongro’ and ‘Gamhong’ apples by different storage methods with PE film package and CA conditions. ‘Hongro’ and ‘Gamhong’ apples grown at the Geochang-city in the southern part of Korea were harvested in September in 2002 for storage study. Each cultivar was divided into two groups of maturity based on the harvest date. Immature fruits were harvested on the early periods of 10 days compared to mature fruits with proper maturity. A typical climacteric respiration pattern was observed in new variety ‘Hongro’ and ‘Gamhong’ apples stored at room temperature. Fruit weight, ethylene production, firmness, and skin color were used as quality indicators for the stored apples. The results indicated that overall fresh qualities of the stored fruits in CA condition was better than apples in no package (control) and PE film package during storage. Quality of apples was changed little in CA storage of 3% CO₂ and 1% O₂. CA storage was effective in maintaining the freshness of ‘Hongro’ and ‘Gamhong’ for 16 weeks.
