Abstract

‘Patrecia’ is a new and distinct southern highbush blueberry (Vaccinium corymbosum L.) variety distinguished by a low chilling requirement, upright-spreading growth habit, and early maturing, firm, juicy fruit that are sweet with balanced acidity.

Description

Latin name of the genus and species of the plant claimed: Vaccinium corymbosum L.
Variety denomination: ‘Patrecia’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct hybrid variety of southern highbush blueberry (Vaccinium corymbosum L.) named ‘Patrecia’. ‘Patrecia’ is a blueberry clone distinguished by its low chilling requirement, vigorous, upright-spreading bush habit, and large, firm berries that ripen from mid-April through May when grown as a deciduous plant in north central Florida and south Georgia. Several thousand plants of ‘Patrecia’ have been propagated by softwood stem cuttings in Waldo, Fla., and the resulting plants have all been phenotypically indistinguishable from the original plant. Contrast is made to ‘Emerald’ (U.S. Plant Pat. No. 12,165), an important variety widely planted in the southeastern United States. The claimed plant is important because it has a more upright-spreading growth habit, and has larger, sweeter fruit than ‘Emerald’. ‘Patrecia’ blooms later and fruit matures earlier than that of ‘Emerald’.
‘Patrecia’ originated as a seedling from a cross made in February 2007 between ‘Star’ (U.S. Plant Pat. No. 10,675) as the female (seed) parent and ‘Springhigh’ (U.S. Plant Pat. No. 16,404) as the male (pollen) parent. The seedling was planted in the field in May 2008 and the first fruit were evaluated in April 2009. After the first evaluation, in the spring of 2009, ‘Patrecia’ was first asexually propagated by softwood stem cuttings in Waldo, Fla., and multiple experimental test plots were established as part field plantings in Waldo and Windsor, Fla., in 2010 through 2012. Based on the growth, yield, and fruit quality of these plots, ‘Patrecia’ was repropagated by softwood stem cuttings and experimental test plots up to 500 plants were established near Homerville, Ga. in 2013. These plots have been observed during flowering and ripening each year, and no mutations or off-type plants have been observed.
‘Patrecia’ differs from the parent ‘Star’ (U.S. Plant Pat. No. 10,675) in that ‘Patrecia’ has a more spreading growth habit, and has more numerous, larger berries that mature earlier. ‘Patrecia’ differs from the parent ‘Springhigh’ (U.S. Plant Pat. No. 16,404) in that ‘Patrecia’ has a more spreading growth habit, and has larger, firmer fruit. ‘Patrecia’ differs from the commercial variety ‘Emerald’ (U.S. Plant Pat. No. 12,165), an important variety widely planted in the southeastern United States, in that ‘Patrecia’ has a more upright-spreading growth habit and blooms later. ‘Patrecia’ berries ripen earlier and are larger and sweeter than ‘Emerald’ berries.
SUMMARY OF THE INVENTION
Blueberry variety ‘Patrecia’ exhibits outstanding and distinguishing characteristics when grown under normal horticultural practices in Florida, including:
    • (1) a low chilling requirement, particularly for the flower buds;
    • (2) a vigorous, upright-spreading growth habit;
    • (3) early ripening (50% ripe berries in North Florida around April 20); and
    • (4) firm, large, sweet berries.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying photographs show typical bush, flower, and fruit characteristics for ‘Patrecia’. Colors shown are as true as can be reasonably reproduced by photographic procedures and may differ from those cited in the detailed description, which accurately describes the colors of ‘Patrecia’.
FIG. 1—Shows several clusters of opening ‘Patrecia’ flowers.
FIG. 2—Shows clusters of ‘Patrecia’ berries during the fruit ripening season.
FIG. 3—Shows a close-up of harvested ‘Patrecia’ berries.
FIG. 4—Shows a close-up of mature ‘Patrecia’ fruit with a scale bar.
FIG. 5—Shows several three-year-old ‘Patrecia’ plants in February with the vigorous, upright-spreading plant architecture visible.
DETAILED BOTANICAL DESCRIPTION
The following detailed description sets forth the distinctive characteristics of ‘Patrecia’. The data that define these characteristics were collected from asexual reproductions carried out in Florida. The plant history was taken on a plot of 150 three-year-old plants growing in a commercial field near Windsor, Fla. Certain characteristics may vary with plant age. ‘Patrecia’ has not been observed under all possible environmental conditions, and the measurements given may vary when grown in different environments. Where means are given, the sample size was 20. Color descriptions are based on The Royal Horticultural Society (R.H.S.) Colour Chart by The Royal Horticultural Society, London, Fifth Edition, 2007. When the RHS color designations differ from the accompanying photographs, the RHS color designations are accurate.

  • Use: ‘Patrecia’ produces southern highbush blueberries suitable for both the fresh and processed fruit markets.
  • Resistance to diseases, insects, and mites: ‘Patrecia’ has grown vigorously and shows excellent bush survival in the field. It appears to be tolerant to stem blight (Botryosphaeria spp.) and root rot (Phytophthora cinnamons), with very few young plants dying soon after planting. The reaction of ‘Patrecia’ to the various fungal species that cause summer leaf spots is typical of other southern highbush varieties, and fungicide applications may be needed after harvest to reduce foliar diseases and retain leaves into the fall for maximum flower bud set. Similarly, susceptibility to typical blueberry insect and mite pathogens such as spotted wing drosophila (Drosophila suzukii), blueberry gall midge (Dasineura oxycoccana) and blueberry bud mite (Acalitus vaccini) is similar to other southern highbush cultivars.
