BACKGROUND OF THE NEW CULTIVAR
The present invention relates to a new and distinct cultivar of Gerbera hybrida (“Gerbera”) cultivar named ‘UFGE 7031’.
Gerbera plants are ornamental plants from the family Asteraceae frequently used as a decorative garden plant or for cut flowers. The inflorescence of the Gerbera plant is a large capitulum with a plurality of florets, which are often brightly colored. The florets may include outer ray florets, trans florets, and central disk florets.
The new Gerbera cultivar ‘UFGE 7031’ is a product of a planned breeding program conducted by the Inventors in Wimauma, Fla. The objective of the breeding program is to develop new Gerbera cultivars with good plant vigor, moderate lengths of peduncles, numerous inflorescences, attractive inflorescence colors, large inflorescence sizes, and moderate to high levels of powdery mildew resistance.
The new Gerbera cultivar ‘UFGE 7031’ originated from a cross made in Wimauma, Fla., in 2005 between the female or seed parent ‘UFGE 5004’ (unpatented) and the male or pollen parent ‘UFGE 5015’ (unpatented). ‘UFGE 5004’ was a Gerbera breeding line that was selected by the inventors in Wimauma, Fla., from progeny of a cross made in Bradenton, Fla., in 2004 between the Gerbera breeding lines ‘UFGE 31-19’ (unpatented) and ‘UFGE 5-23’ (unpatented). The male parent ‘UFGE 5015’ was progeny of a cross between the commercial cultivar ‘Sunburst Fuchsia’ (unpatented) and a Gerbera breeding line ‘UFGE 3714’ (unpatented). The new Gerbera cultivar ‘UFGE 7031’ was selected by the inventors from the progeny of the stated parentage in summer 2007 in Wimauma, Fla.
The first asexual reproduction of the new Gerbera cultivar ‘UFGE 7031’ was accomplished by crown division in late 2007 in Wimauma, Fla. Since then, the new Gerbera has been asexually propagated by crown division and/or tissue culture for more than four generations. Asexually propagated plants of the new Gerbera have remained true to the original plant, and all characteristics of the new Gerbera have been transmitted and retained through three successive asexual vegetative generations.
Plant Breeder's Rights for this cultivar have not been applied for. The new Gerbera cultivar has not been made publicly available more than one year prior to the filing of this application.
SUMMARY OF THE INVENTION
Plants of the new Gerbera cultivar ‘UFGE 7031’ have not been observed under all possible environmental conditions. Its phenotype may vary significantly with variations in environment such as light intensity, temperature, and day length, and cultural practices such as fertilization and irrigation, without any variance in genotype.
The following traits are the most outstanding and distinguishing characteristics of this new and unique Gerbera cultivar when grown in Wimauma, Fla., under normal horticultural practices in greenhouse conditions which closely approximate those generally used in commercial practice:
    • 1. Freely flowering habit;
    • 2. Medium peduncle length of approximately 40 cm;
    • 3. Single inflorescence type;
    • 4. Orange-red (RHS 30C) ray florets;
    • 5. Greyed-purple (RHS 187A) discs before opening of disc florets;
    • 6. Inflorescence diameter of approximately 12 cm;
    • 7. High level of resistance to powdery mildew; and
    • 8. Good heat tolerance.
Plants of the new Gerbera cultivar ‘UFGE 7031’ differ from the female parent ‘UFGE 5004’ (unpatented) in the following characteristics:
    • 1. Plants of the new Gerbera cultivar ‘UFGE 7031’ and the female parent ‘UFGE 5004’ differ in ray floret color as plants of the female parent have light pink ray florets; and
    • 2. Plants of the new Gerbera ‘UFGE 7031’ and the female ‘UFGE 5004’ parent differ in disc floret color as plants of the female parent have yellow-green disc florets.
Plants of the new Gerbera cultivar ‘UFGE 7031’ differs from the male parent ‘UFGE 5015’ (unpatented) in the following characteristics:
    • 1. Plants of the new Gerbera cultivar ‘UFGE 7031’ and the male parent ‘UFGE 5015’ differ in inflorescence form as plants of the male parent have semi-double inflorescences;
    • 2. Plants of the new Gerbera cultivar ‘UFGE 7031’ and the male parent ‘UFGE 5015’ differ in ray floret color as the plants of the male parent have dark rose ray florets;
    • 3. Plants of the new Gerbera cultivar ‘UFGE 7031’ and the male parent ‘UFGE 5015’ differ in disc floret color as the plants of the male parent have dark rose disc florets; and
    • 4. Plants of the new Gerbera cultivar ‘UFGE 7031’ and the male parent ‘UFGE 5015’ differ in powdery mildew resistance as the plants of the male parent are highly susceptible to powdery mildew.
The new Gerbera cultivar ‘UFGE 7031’ can be compared to Gerbera hybrida ‘UFGE 4141’, disclosed in U.S. Plant Pat. No. 23,346. Plants of the new Gerbera cultivar ‘UFGE 7031’ differ from plants of ‘UFGE 4141’ in the following characteristics:
    • 1. Plants of the new Gerbera cultivar ‘UFGE 7031’ and ‘UFGE 4141’ differ in inflorescence form as plants of ‘UFGE 4141’ have semi-double inflorescences;
    • 2. Ray florets of the new Gerbera cultivar ‘UFGE 7031’ are less red than the ray florets of ‘UFGE 4141’ (RHS 33B);
    • 3. Plants of the new Gerbera cultivar ‘UFGE 7031’ and ‘UFGE 4141’ differ in disc floret color as plants of ‘UFGE 4141’ have a yellow-green disc before opening of disc florets; and
    • 4. Plants of the new Gerbera cultivar ‘UFGE 7031’ have shorter peduncles as the peduncles of ‘UFGE 4141’ are approximately 52 cm.
The new Gerbera cultivar ‘UFGE 7031’ can be compared to Gerbera hybrida ‘UFGE 7034’, disclosed in U.S. Plant Pat. No. 23,433. Plants of the new Gerbera cultivar ‘UFGE 7031’ differ from plants of ‘UFGE 7034’ in the following characteristics:
    • 1. Plants of the new Gerbera cultivar ‘UFGE 7031’ and ‘UFGE 7034’ differ in inflorescence form as plants of ‘UFGE 7034’ have double inflorescences;
    • 2. Plants of the new Gerbera cultivar ‘UFGE 7031’ and ‘UFGE 7034’ differ in disc floret color as plants of ‘UFGE 7034’ have a yellow-green (RHS 151D) disc before opening of the disc florets; and
    • 3. Plants of the new Gerbera cultivar ‘UFGE 7031’ have higher levels of powdery mildew resistance than plants of ‘UFGE 7034’.

  • Resistance to diseases: Plants of the new Gerbera cultivar ‘UFGE 7031’ were observed in five experiments in which they were compared with plants of commercial Gerbera cultivars, ‘Bimini’ (unpatented), ‘Pensacola’ (unpatented), ‘FUNTASTIC™ Canary’ (‘UFGE 7032’), and/or ‘FUNTASTIC™ Fire Orange’ (‘UFGE 4141’), for the severity of powdery mildew, Podosphaera (syn. Sphaerotheca) fusca (Fr.) S. Blumer. Plants of the new Gerbera cultivar ‘UFGE 7031’ consistently showed a high level of resistance to powdery mildew. The five experiments were conducted in Wimauma, Fla.: Experiment 1 was conducted from winter 2008 to spring 2009, Experiments 2 and 3 were conducted from summer to fall 2009, and Experiments 4 and 5 were conducted from spring to summer 2012. In all experiments, tissue culture liners of the new Gerbera, ‘Bimini’, ‘Pensacola’, ‘FUNTASTIC™ Canary’, and/or ‘FUNTASTIC™ Fire Orange’ were transplanted into 2.7-L containers filled with commercial potting mix amended with controlled release fertilizer at the rate of 5.28 kg·m−3 and trace element fertilizer at the rate of 1.05 kg·m−3. In Experiments 1, 3 and 4, all plants were grown in a screen house in Wimauma, Fla., without temperature or photoperiod control but with approximately 45% light exclusion. In Experiments 2 and 5, plants were grown in a greenhouse in Wimauma, Fla. The greenhouse had approximately 30% light exclusion and temperature inside the greenhouse was between 21° C. (night) to 35° C. (day). Fungicides were not applied throughout the experiments to subject the plants to natural powdery mildew disease pressures. A randomized complete block design was used in these experiments, with five (Experiment 1), five (Experiment 2), six (Experiment 3), four (Experiment 4), or six (Experiment 5) replications. The experimental unit was a single containerized plant. Severity of powdery mildew on plants was assessed using a scale of 1 to 10 as described by Hausbeck et al. (2002) in March 2009 (Experiment 1), June 2009 (Experiment 2), October 2009 (Experiment 3), and August 2012 (Experiments 4 and 5). Plants of the new Gerbera cultivar received the lowest powdery mildew severity ratings in all experiments, and its rating was below 3.0 in four experiments. These results indicate a high level of powdery mildew resistance in the new Gerbera cultivar. No other disease resistance characterizations have been made. Table 1. Powdery mildew severity ratings of the new Gerbera cultivar ‘UFGE 7031’ and commercial Gerbera cultivars, ‘Bimini’, ‘Pensacola’, ‘FUNTASTIC™ Canary’, and/or ‘FUNTASTIC™ Fire Orange’, grown under natural powdery mildew pressure in five experiments in Wimauma, Fla.: Experiment 1 (winter 2008 through spring 2009), Experiments 2 and 3 (summer 2009 through fall 2009), and Experiments 4 and 5 (spring 2012 through summer 2012).
