Funtastic™ Gerbera Daisy Varieties for Large Containers
and Flower Gardens1
Zhanao Deng2
Gerbera daisy is a popular flower throughout the world
(Tjia, Black, and Park Brown 2008). Many people enjoy
growing this flower in gardens or large containers. Six new
varieties have been released recently by the University of
Florida/IFAS gerbera breeding program at the Gulf Coast
Research and Education Center in Wimauma, Florida
(Deng and Harbaugh 2010). These varieties have been
selected and tested specifically for use in large containers
and flower gardens and can produce high-quality plants
with numerous bright-colored flowers (Table 1). Flower
stems (peduncles) of these varieties are 12–18 inches long
and are ideal for eye-catching color displays in the garden
and large containers, or for use as cut flowers, either alone
or as part of a larger arrangement. Greenhouse trials have
shown that these new varieties bloom earlier and produce
more flowers than existing commercial varieties. Additionally, these varieties seem to be more resistant to or tolerant
of powdery mildew, the most common and damaging
fungal disease in gerbera (Moyer and Peres 2012).

Table 1 describes quality and flower production for six new
gerbera varieties and two commercial varieties (checks)
evaluated in winter 2008 and spring 2009 (Experiment 1)
and summer and fall 2009 (Experiment 2) in Wimauma,
Florida. Tissue culture liners of these varieties from AgriStarts, Inc., Apopka, Florida, were planted in gallon plastic
containers filled with Fafard 3B potting mix amended with
15-9-12 Osmocote® controlled release fertilizer (9 lb. per
cubic yard) and MicroMax trace element fertilizer (1.8 lb.
per cubic yard). Plants were grown in the greenhouse and
sprayed with insecticides or fungicides as necessary.
Powdery Mildew Resistance
Two experiments (Experiments 3 and 4) were conducted
to evaluate the resistance or susceptibility of these gerbera
varieties to powdery mildew and their flower production
under natural powdery mildew disease pressure. Experiment 3 was performed in winter 2008 and spring 2009, and
Experiment 4 was performed in summer and fall 2009. The
causal agent of powdery mildew at the experiment sites
was Podosphaera (syn. Sphaerotheca) fusca (Fr.) S. Blumer
(Moyer and Peres 2008).
‘Funtastic™ Blush’ had the lowest powdery mildew severity
ratings (averaged 3.6), significantly lower than the ratings
of the two commercial varieties (checks) (8.0–8.6), thus
indicating a considerable level of powdery mildew resistance in this variety (Table 2). Its powdery mildew severity
rating was also significantly lower than that of the other
Funtastic™ gerberas.
‘Funtastic™ Fire Orange’ and ‘Funtastic™ Mango’ were less
susceptible to powdery mildew than the checks (Table
2). ‘Funtastic™ Fire Orange’ and ‘Funtastic™ Mango’ were
the most floriferous in Experiment 4 and moderately
floriferous in Experiment 3 when natural powdery mildew
disease pressure existed. Similarly, ‘Funtastic™ White’ was
significantly less susceptible to powdery mildew than the
checks in Experiment 4 throughout the evaluation. It had
lower severity ratings than the checks in Experiment 3, but
the differences were not statistically significant. ‘Funtastic™
White’ remained more floriferous than the checks in both
Experiments 3 and 4.
‘Funtastic™ Yellow’ and ‘Funtastic™ Canary’ had lower
powdery mildew severity ratings than the checks in Experiment 4 (6.0–6.1 vs. 9.4–9.8), but their ratings in Experiment
3 were close to those of the checks (Table 2). In both tests,
‘Funtastic™ Yellow’ and ‘Funtastic™ Canary’ produced more
flowers than the checks.

Note: Scores before and after the slash indicate data collected from Experiments 1 and 2, respectively. A dash indicates that data were
not collected. Plant quality was rated using a scale of 1–5, where 1 = few leaves or long petioles, very poor, and unacceptable, 3 = fair, and 5
= excellent, full, attractive, symmetrical plants. Flower quality was rated on a scale of 1–5, where 1 = very poor, 3 = fair, some blemishes, but
acceptable, and 5 = excellent, bright, uniform, and no blemishes.

Note: Plants were grown under natural powdery mildew pressure in winter 2008 and spring 2009 (Experiment 3) and summer and fall 2009
(Experiment 4) in Wimauma, Florida. Powdery mildew severity was rated on a scale of 1–10 (Hausbeck, Quackenbush, and Linderman 2002),
where 1 = no disease, 2 = trace to 10% of leaf surface covered with powdery mildew, 3 = 10%–20%, 4 = 20% –30%, 5 = 30%–40%, 6 = 40%–50%, 7 =
50%–60%, 8 = 60%–70%, 9 = 70%–80%, and 10 = 80%–100%.
