Abstract
A southern highbush blueberry (Vaccinium corymbosum L.) variety particularly distinguished by a very low chilling requirement (200 hours below 7° C.) with prolific early-spring leafing, a vigorous bush, a very early ripening (50% ripe berries in north Florida about April 21), and berries that are firm, sweet, and aromatic in flavor.
Description
The present invention was supported in part by funds from the U.S. Government. The U.S. Government therefore may have certain rights in the invention.
Genus and species: Vaccinium corymbosum L.
Variety denomination: ‘FL02-40’.
The invention relates to a new and distinct variety of southern highbush blueberry (Vaccinium corymbosum L.) hybrid plant named ‘FL02-40.’ ‘FL02-40’ is a southern highbush blueberry clone distinguished by its very low chilling requirement, its prolific early-season leafing, and firm, sweet, aromatic berries that ripen during April when grown in north Florida. Several hundred plants of ‘FL02-40’ have been propagated by softwood cuttings at Gainesville, Fla., and the resulting plants have all been phenotypically indistinguishable from the original plant. Contrast is made to ‘Star’ (U.S. Plant Pat. No. 10,675), an important variety widely planted in Florida and Georgia for early-season blueberry production. The new variety is important because it has a lower chilling requirement than ‘Star,’ ripens earlier in the season, and has a sweeter, more aromatic berry.
‘FL02-40’ originated as a seedling from the cross ‘FL95-54’ (unpatented)בFL97-125’ (unpatented) made as part of the University of Florida breeding program in a greenhouse at Gainesville, Fla. in February 1999. The seedling was first fruited in a high-density field nursery in the spring of 2001. After the second year of fruiting in the field, in the spring of 2002, ‘FL02-40’ was propagated by softwood cuttings, and an experimental 15-plant test plot was established as part of a variety test at Windsor, Fla. in February 2003. Based on the early-season ripening and high berry quality of this plot, ‘FL02-40’ was repropagated by softwood cuttings in June 2005, and new test plots were planted the following winter at Windsor, Waldo, and Haines City, Fla. These plots, and the original plot, have been observed annually from flowering through fruit ripening each year, and no mutations or off-type plants have been observed.
The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Florida.
-
- 1. A very low chilling requirement with prolific early-spring leafing;
- 2. A vigorous bush;
- 3. Very early ripening (50% ripe berries in north Florida about April 21); and
- 4. Berries that are firm, sweet, and aromatic in flavor.
The color chart used in this specification is “The Pantone Book of Color” (by Leatrice Eiseman and Lawrence Herbert; Harry N. Abrams, Inc., Publishers, New York, 1990). Where colors in the drawings differ from the Pantone color designations in the descriptions, the Pantone color designations are accurate. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.
The following detailed description sets forth the distinctive characteristics of ‘FL02-40.’ The data which define these characteristics were collected from asexual reproductions carried out in Florida. The plant history was taken on 3½-year-old plants. The following descriptions relate to plants grown in the field in north Florida (Windsor, Fla.). Color designations are from “The Pantone Book of Color” (by Leatrice Eiseman and Lawrence Herbert, Harry N. Abrams, Inc., Publishers, New York, 1990). Where the Pantone color designations differ from the colors in the drawings, the Pantone colors are accurate.

- Weight of well-developed dried seed.—0.6 mg per seed.
- Length of well-developed dried seed (mean).—0.2 cm.
-
- Resistance to diseases, insects, and mites: ‘FL02-40’ is highly vigorous, but has shown only medium survival in the field in northeast Florida. Because it flowers and leafs very early, it is subject to damage during late freezes. ‘FL02-40’ should be planted on well-drained soil and is best adapted in areas where January and February freezes are less severe than in Gainesville. ‘FL02-40’ is expected to grow well in blueberry growing areas with low summer rainfall. The reaction of ‘FL02-40’ to the fungal species that cause summer leaf spots is typical of other southern highbush cultivars, and fungicide applications may be needed after harvest to reduce foliar diseases.
‘FL02-40’ differs from the proprietary female (seed) parent ‘FL95-54’ (unpatented) in that ‘FL02-40’ has a larger berry, more prolific early-spring leafing, and a somewhat more spreading growth habit than ‘FL95-54.’
‘FL02-40’ differs from the male (pollen) parent ‘FL97-125’ (unpatented) in that ‘FL02-40’ has a more vigorous bush, larger leaves, a larger berry, and a sweeter, more aromatic flavor than ‘FL95-54.’
‘FL02-40’ differs from the commercial variety ‘Star’ (U.S. Plant Pat. No. 10,675), an important variety widely planted in Florida and Georgia for early-season blueberry production, in that ‘FL02-40’ has a lower chilling requirement, ripens earlier in the season, and has a sweeter, more aromatic berry than ‘Star.’
