Abstract

A new and distinct cultivar of Vaccinium plant named ‘TO-3097’, characterized by a combination of unique pink-colored fruit, mid-season flowering and ripening, large berries with good firmness and flavor, high quality fruit production in conventional production areas, and a chilling requirement of about 450-500 hours below about 45° F.

Description

Botanical designation: Vaccinium virgatum.
Cultivar denomination ‘TO-3097’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of rabbiteye blueberry plant, botanically know as Vaccinium virgatum, and hereinafter referred to by the cultivar name ‘TO-3097’.
The new Vaccinium virgatum ‘TO-3097’ was first identified in 2016 in Griffin, Ga. The new pink-fruited variety ‘TO-3097’ is mid-season, has large berries with unique pink color and good flavor and firmness, with no observed notable diseases or other pest problems beyond those also common for other varieties, and a chilling requirement of about 450-500 hours below about 45° F.
‘TO-3097’ is a product of a cross of ‘T-459’ (non-patented breeding selection) X ‘T-743’ (another non-patented breeding selection) made by D. Scott NeSmith in 2014. The new blueberry plant variety ‘TO-3097’ has been tested in asexually propagated (by vegetative cuttings) plantings in Alapaha, Ga. since 2018 where it was established for testing and comparing to industry standards. Observations of the resulting ‘TO-3097’ progeny have shown that the unique features of this new Vaccinium virgatum ‘TO-3097’ are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The new Vaccinium cultivar ‘TO-3097’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, water and fertility levels, soil types, and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique and distinguishing characteristics of the new Vaccinium virgatum cultivar named ‘TO-3097’. In combination, these traits set ‘TO-3097’ apart from all other existing varieties of rabbiteye blueberry known to the inventors.
    • 1. unique pink fruit color in various shades of pink, from wine-colored to lavender
    • 2. large fruit with good flavor
    • 3. mid-season for flowering and ripening in mid chill production regions
    • 3. no significant diseases or pests not also common to other rabbiteye varieties.
    • 4. high quality fruit production in conventional production areas with supplemental irrigation
Comparison: As compared to the female parent ‘T-459’ and male parent ‘T-743’, plants of the new Vaccinium cultivar ‘TO-3097’ have a chilling requirement of about 450-500 hours, which is intermediate to ‘T-459’ (500 to 600 hours) and ‘T-743’ (300 to 400 hours). Both parents have typical medium to light blue fruit when mature, whereas, ‘TO-3097’ has the atypical pink hued, wine-colored fruit described earlier. ‘TO-3097’ flowers and ripens some 5 to 7 days later than ‘T-743’ and 5 to 7 days earlier than ‘T-459’. Berry size of ‘TO-3097’ is similar to both parents.
Plants of the new Vaccinium virgatum can also be compared to other early season rabbiteye blueberry cultivars ‘T-1101’ Krewer™ (U.S. Plant Pat. No. 28,623) and ‘T-959’ Titan™ (U.S. Plant Pat. No. 24,135). The selection ‘TO-3097’ is mid-season and begins flowering around the same time as ‘T-1101’ Krewer™ but before ‘T-959’ Titan™ in South Georgia. It ripens near the time of ‘T-959’ Titan™ and after ‘T-1101’ Krewer™. ‘TO-3097’ has large berries, but smaller than both ‘T-959’ Titan™ and ‘T-1101’ Krewer™. ‘TO-3097’ has very good flavor and firmness (Table 1). Fruit color is very different than the medium to light blue fruit typical for Rabbiteye blueberries, including both ‘T-959’ Titan™ and ‘T-1101’ Krewer™. Instead, ‘TO-3097’ develops a mature fruit color that is various shades of pink, wine-colored, and lavender (see drawings). No notable diseases or other pest problems have been observed for the new variety that are not also common for other varieties. The new variety is estimated to have a chilling requirement of 450-500 hours, more or less, below 45° F. (based on comparison of flowering dates with those of known standard cultivars) when produced under typical mid chill production regions. Studies suggest that ‘TO-3097’ produces high quality fruit when grown in conventional production areas. Additional comparison data of ‘TO-3097’ with ‘T-959’ Titan™ and ‘T-1101’ Krewer™ are presented in the table below.

 DETAILED BOTANICAL DESCRIPTION
The following traits have been consistently observed in the original plant of this new variety and in asexually propagated progeny grown in Alapaha, Ga., and, to the best knowledge of the inventors, their combination forms the unique characteristics of the new variety Vaccinium virgatum ‘TO-3097’.
Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. Color names beginning with a capital letter designate values based upon The R.H.S. Colour Chart, 5th edition published by The Royal Horticultural Society, London, England in 2007, except where general terms of ordinary dictionary significance are used.
The aforementioned photographs and following observations, measurements, and values describe plants of the Vaccinium virgatum cultivar named ‘TO-3097’. Data were collected between the years of 2019-2020 from a horticulture farm and nursery in Alapaha, Ga. from 3 to 4-year-old plants (planted in the field with supplemental irrigation). The average low temperature for the year ranges from about 54° F. to 58° F., and the average high temperature for the year ranges from about 78° F. to 82° F.
