Abstract

A new and distinct low-chill, tetraploid highbush blueberry (Vaccinium) variety of complex ancestry, based largely on V. corymbosum L. with some genes from V. darrowi Camp. Its novelty consists of the following unique combination of features: 1. Produces fruit which, when chilled to 10° C., has a distinct crisp or crunchy texture. 2. Flowers and leafs vigorously in Florida in areas where the mean temperature of the coldest month is 58° F. or colder. 3. Ripens its fruit 60 days after flowering in north-central Florida. 4. Ripens 80% of its fruit between April 20 and May 15 in north-central Florida. 5. Produces fruit that are large, firm, have a good picking scar, and a good flavor. 6. Produces a bush that is semi-upright and vigorous, with good resistance to Phytophthora cinnamomi and Botryosphaeria dothedia. 7. Can readily be propagated by softwood cuttings.
