The southern highbush blueberry (Vaccinium, mostly corymbosum) cultivars Jubilee, Pearl River, and Magnolia and the rabbiteye cultivars Climax and Premier were stored for 4 weeks at 1-2 °C. Berries were held in pint “clam shell” plastic retail units and were evaluated weekly for physical and compositional quality. As groups, the rabbiteyes were higher in SSC, SSC/TA, glucose and fructose, anthocyanins, and malic, quinic, and succinic acids. `Jubilee' was the southern highbush and `Climax' the rabbiteye least affected by the storage. `Pearl River' and `Magnolia' were less firm and more shriveled than the other cultivars. `Magnolia' had the highest incidence of decay; decay was slight overall.
