Description

Genus and species: Caladium x hortulanum.

Cultivar denomination: ‘Pink Panther’.

BACKGROUND OF THE NEW CULTIVAR

The present invention relates to a new and distinct cultivar of Caladium, botanically known as Caladium x hortulanum, and hereinafter referred to by the name ‘Pink Panther’. Caladium plants are tuberous-rooted plants and typically have attractive heart-shaped or arrow-shaped leaves on long stalks rising directly from the tubers. Foliage may grow in a variety of colors and variegation patterns, and many species have been developed for aesthetic coloration, good container and landscape growth, drought tolerance, pest resistance, and other desirable characteristics.

Plant Breeder's Rights for this cultivar have not been applied for. The new Caladium cultivar ‘Pink Panther’ has not been made publicly available more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

The new Caladium cultivar ‘Pink Panther’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment and cultural practices such as temperature, light intensity, fertilization, irrigation, and application of plant growth regulators without any change in genotype.

The objective of the breeding program that produced the present cultivar was to develop cultivars that have novel foliar characteristics, produce multiple brightly colored leaves, have good tuber yield potential, and perform well in containers and the landscape. The present Caladium cultivar originated from a cross-pollination made in Balm, Fla., in the summer of 2012 between the Caladium x hortulanum cultivar ‘Carolyn Whorton’ (not patented), as the female or seed parent, and the Caladium x hortulanum proprietary breeding line UF4609 (not patented), as the male or pollen parent. The new Caladium cultivar was discovered and selected by the inventor as a single plant within the progeny of the stated cross-pollination in Balm, Fla., in the spring of 2014. Breeding line UF4609 was a progeny of a cross made in 2004 between the Caladium x hortulanum variety ‘Cranberry Star’ (U.S. Plant Pat. No. 20,792) and the Caladium x hortulanum variety ‘Florida Sweetheart’ (U.S. Plant Pat. No. 8,526; patent expired).

Asexual reproduction of the new cultivar ‘Pink Panther’ by tuber division has been performed annually since 2014. The unique features of this new Caladium cultivar are stable and reproduced true to type in successive generations of asexual reproduction.

The following traits have been repeatedly observed and are determined to be the unique characteristic of ‘Pink Panther’. These characteristics in combination distinguish ‘Pink Panther’ as a new and distinct cultivar of Caladium:

    • 1. Wide lance or strap-type leaves that have a large deep pink center, deep pink main and primary veins, and irregular blotches of variable sizes and shapes in light pink to white, and ruffled deep green margins;
    • 2. Upright and sturdy petioles and upright plant growth habit;
    • 3. Full yet compact plant habit suitable for planting in containers;
    • 4. Tolerance to Xanthomonas bacterial leaf blight and sunburns; and
    • 5. Suitable for shady or sunny landscape locations.

Plant of the new Caladium cultivar ‘Pink Panther’ differ from plants of the female parent, ‘Carolyn Whorton’, in the following characteristics:

    • 1. Plants of ‘Pink Panther’ are more compact, and are much shorter and narrower than plants of ‘Carolyn Whorton’;
    • 2. Leaves of ‘Pink Panther’ are of the lance-type with a netted palmate venation and with petioles attached to the base, whereas petioles of ‘Carolyn Whorton’ are attached at within the leaf blade;
    • 3. Leaves of ‘Pink Panther’ have a deep pink center and deep pink main and primary veins, whereas leaves of ‘Carolyn Whorton’ have a lighter pink center;
    • 4. Leaves of ‘Pink Panther’ are smaller than those of ‘Carolyn Whorton’; and
    • 5. Bases of leaves of ‘Pink Panther’ vary from being sagittate, to cordate, to truncate.

Plants of the new Caladium cultivar ‘Pink Panther’ differ from plants of the male parent, breeding line UF4609, in the following characteristics:

    • 1. Plants of ‘Pink Panther’ are taller and larger than those of breeding line UF4609;
    • 2. Petioles of ‘Pink Panther’ are sturdy and upright, whereas petioles of breeding line UF4609 are softer; and
    • 3. Leaves of ‘Pink Panther’ are longer and wider than those of breeding line UF4609, and have a large deep pink center and deep pink main veins.

Plants of the new Caladium cultivar ‘Pink Panther’ can be compared to ‘Florida Red Ruffles’ (U.S. Plant Pat. No. 13,136). In side-by-side comparisons conducted in Wimauma, Fla., plants of the new Caladium cultivar ‘Pink Panther’ differed from plants of ‘Florida Red Ruffles’ in leaf coloration and overall plant appearance, with ‘Florida Red Ruffles’ having dark red leaves and soft petioles.

Plants of the new Caladium cultivar ‘Pink Panther’ can be compared to ‘Florida Sweetheart’ (U.S. Plant Pat. No. 8,526). In side-by-side comparisons conducted in Wimauma, Fla., plants of the new Caladium cultivar ‘Pink Panther’ differed from plants of ‘Florida Sweetheart’ in leaf coloration pattern and growth habit, with plants of ‘Florida Sweetheart’ having leaves that are bright pink in color without any blotches. ‘Florida Sweetheart’ also has soft petioles and leaves that cascade from the center to the sides of the plant.

Description of Growing Conditions

The aforementioned photographs and the following observations and measurements describe plants grown in 20.3-cm containers in Wimauma, Fla., during the summer in a polypropylene-covered greenhouse and plants grown in beds in Wimauma, Fla., during the late summer in an outdoor nursery. All plants were grown under conditions and practices that approximate those generally used in commercial Caladium production.

During the production of the plants, day temperatures ranged from about 75° F. to about 93° F., night temperatures ranged from about 66° F. to about 77° F., and light levels were about 30% reduced in the greenhouse or full sun in the outdoor nursery. Plants grown in the greenhouse were about seven weeks from planting tubers when the photographs and the detailed description were taken. Plants grown in the outdoor nursery were about twelve weeks from planting tuber pieces when the photographs and the detailed description were taken.

        Disease Resistance

Plants of the new Caladium cultivar ‘Pink Panther’ have been observed to show resistance to Xanthomonas bacterial leaf blight. In field trials in Florida, the Xanthomonas bacterial leaf blight resistance score of ‘Pink Panther’ ranged from 3.7 to 4.8 on a scale of 1 to 5, with 1=highly susceptible and 5=strongly resistant.

Sunburn Resistance

Plants of the new Caladium cultivar ‘Pink Panther’ have been observed to show resistance to sunburns. In field trials conducted in Florida, the sunburn resistance score of ‘Pink Panther’ ranged from 3.0 to 4.7 on a scale of 1 to 5, with 1=highly sensitive and 5=highly resistant to sunburns.

Tuber Yield Potential

‘Pink Panther’ was evaluated for tuber yield potential in Balm, Fla., in 2018 and 2019. The soil was Eau Gallie fine sand with about 1% organic matter and a pH of between 6.2 and 7.4. Caladium plants were grown in the field on white plastic-mulched raised beds. In the 2018 season, ground beds (81 cm in width, 20 cm in height) were fumigated on Feb. 13, 2018, with Pic-Clor 60 (39.0% 1,3-dichloropropene, 59.6% chloropicrin) at 448 kg·ha−1 and Prowl® H2O (BASF SE, Germany). Caladium seed tubers were treated in hot water (50° C.) for 30 minutes. Seed tuber pieces (approximately 2.5×2.5×2.5 cm) were dusted with a biological fungicide RootShield® Plus WP (BioWorks, Victor, N.Y.) and planted manually on Apr. 27, 2018, with approximately 25.4 cm between-row spacing and approximately 15.2 cm in-row spacing. Fifty pounds of granular nitrogen (50 N) per acre was incorporated into the soil prior to bedding. Two drip tapes were buried under the plastic mulch along the raised beds, which provided the irrigation water and fertilization. Fertigation began on May 29, 2018, injecting a commercial liquid fertilizer (5N-0.87P-6.64K) at the rate of 0.454 kg of nitrogen an acre a day, and stopped on Oct. 31, 2018. New crop tubers were dug and washed on Dec. 17, 2018, and air-dried for approximately 50 days inside a greenhouse. Dried tubers from each experimental field plot were weighed, graded, and counted on Feb. 6, 2019. Tuber grading was by the maximum diameter: Super Mammoth (greater than 11.4 cm), Mammoth (8.9 to 11.4 cm), Jumbo (6.4 to 8.9 cm), No. 1 (3.8 to 6.4 cm), and No. 2 (2.5 to 3.8 cm). Tuber grades and counts were converted into a production index to show the relative economic value of the harvested tubers per field plot: Production index=8 n (Super Mammoth)+6 n (Mammoth)+4 n (Jumbo)+2 n (No.1)+1 n (No.2), where n=number of tubers in the grade. The relative values assigned to the five tuber grades in calculating production index were based on the relative market prices provided by Florida Caladium tuber producers.

For the 2019 season, beds were fumigated on Feb. 24, 2019, with Pic-Clor 60 at 448 kg·ha−1. Caladium seed pieces were planted on Apr. 4, 2019. Fifty pounds of granular nitrogen (50 N) per acre was incorporated into the soil prior to bedding. Fertigation began on Jun. 1, 2019, by injecting a commercial liquid fertilizer (5N-0.87P-6.64K) at 0.454 kg of nitrogen per acre per day. The fertilization rate was increased to 0.908 kg of nitrogen per acre per day on Jul. 24, 2019, and ended on Oct. 31, 2019. Tubers were dug and washed on Dec. 9, 2019, dried in the greenhouse for approximately 45 days, and weighed, graded, and counted on Jan. 21, 2020, using the same protocol that was used in 2018.

In both seasons, field plots were arranged in a randomized complete block design with three replicates. The plot size was 1.2 m2 and was planted with 30 Caladium propagules (tuber pieces). In 2018, two cultivars ‘UF 4412’ (US Plant Pat. No. 25,612; commercially sold under the trade name FAIRYTALE PRINCESS™) and ‘UF 4424’ (US Plant Pat. No. 25,598; commercially sold under the trade name RED HOT™) were included in the field as checks to assess the tuber yield and plant performance of ‘Pink Panther’. In the 2019 season, ‘Florida Sweetheart’ was included in the trial as a check. Analysis of variance was conducted using the JMP Pro 15.0.0 program, followed by means comparisons using the Tukey-Kramer HSD test (The SAS Institute, Inc., Cary, N.C., 2019).

The number, weight, and production index of marketable tubers (Grade No. 2 to Super Mammoth) produced by ‘Pink Panther’ in 2018 was 59.0, 1.83 kg, and 87.7, respectively, all significantly higher than those of ‘UF 4412’ ‘UF 4424’ (Table 1). The two checks grew very poorly and their tuber weight was only 6% to 9% of the tuber weight of ‘Pink Panther’. The reasons for the poor growth and yield of ‘UF 4412’ and ‘UF 4424’ remained to be found. It was suspected that these two cultivars might be sensitive to the herbicide Harmony® (FMC Agricultural Caribe Industries, Ltd., Bermuda), which was applied to the bed top and plants in early June 2018 to control weeds in the field. In the 2019 growing season, the number, weight, and production index of marketable tubers for ‘Pink Panther’ were 46.7, 1.96, and 77.0, respectively. Compared to ‘Florida Sweetheart’, a high-yielding cultivar, ‘Pink Panther’ did not show significant differences. As for tuber grade distribution, ‘Pink Panther’ primarily produced No. 1- or No. 2-sized tubers and a low percentage of Jumbos. This tuber size distribution is typical with lance-leaved cultivars including ‘Florida Sweetheart’.

Container Trials

The suitability of ‘Pink Panther’ for container plant production was evaluated by forcing tubers in 11.4-cm containers (diameter) in spring/summer of 2019. Number 1-sized tubers were planted on May 31, 2019, in the commercial potting mix Pro-Line 4B (Jolly Gardener, Poland Spring, Me.) amended with Osmocote® (Everris International B.V., Netherlands) fertilizer (15N-3.9P-10K, 5-6 months) at 4.3 kg·m−3 and Micromax® (Everris International B.V., Netherlands) at 0.48 kg·m−3, and plants were grown in a greenhouse with approximately 30% light exclusion. Temperatures in the greenhouse ranged from 25° C. (night) to 33° C. (day). Potted plants were arranged on metal benches, with a pot-to-pot spacing of 0.4 meters, in the greenhouse in a randomized complete block design with seven replicates. Plant height, plant width, number of leaves, and foliar characteristics were recorded on Jul. 23. and Jul. 24, 2019, approximately eight weeks after planting. Quality of the potted Caladium plants was rated on a scale of 1 to 5, with 1=very poor, unattractive, totally unacceptable as potted plants with few leaves, and 5=very attractive, full plants with a symmetrical shape, an appropriate height, and many bright, colorful leaves. ‘Florida Red Ruffles’ and ‘Florida Sweetheart’ were included as checks in the container trial. ANOVA and mean comparisons were conducted as described above.

Intact and de-eyed ‘Pink Panther’ tubers sprouted 24 to 27 days after potting up, similar to ‘Florida Red Ruffles’ (16 to 27 days) but about 7 to 13 days later than ‘Florida Sweetheart’ (Table 2). ‘Pink Panther’ plants from intact tubers had an upright growth habit and were 5 to 6 cm taller than ‘Florida Red Ruffles’ and ‘Florida Sweetheart’, but did not show significant differences in plant width (34.6 vs. 35.4 or 36.3 cm), leaf number (8.9 vs. 7.4 or 10.7), leaf length (19.1 vs. 18.6 or 19.3 cm) and leaf width (14.0 vs. 4.0 or 14.9 cm), or plant quality rating (2.7 vs. 2.5 or 3.1). Similarly, ‘Pink Panther’ plants forced from de-eyed tubers did not show significant differences from ‘Florida Red Ruffles’ and ‘Florida Sweetheart’ in plant height (19.6 cm) and width (32.2), leaf number (13.9), length (15.1 cm) and width (9.1 cm), and plant quality rating (3.7). Compared to plants from intact tubers, ‘Pink Panther’ plants forced from de-eyed tubers were approximately 5 cm shorter and narrower (about 2.4 cm) and had five more leaves, and on average leaves were 4 cm shorter and about 5 cm narrower (FIG. 3). Overall, plants from de-eyed tubers had more leaves, more uniformed leaves, and received a higher quality rating (3.7 vs. 2.7). Tuber de-eyeing was beneficial and may be essential for producing high quality pot plants from ‘Pink Panther’ tubers.
