'KALAPANA', 'TROPIC ICE', AND 'TROPIC MIST' ANTHURIUM
 Three anthurium selections,
UH1016, UH1051, and UH780, were named 'Kalapana', 'Tropic Ice', and 'Tropic
Mist' respectively. 'Kalapana' represents the first anthurium cultivar to
be patented by the University of Hawaii.
'Kalapana' (UH1016)
'Kalapana' was
selected on April 10, 1983 from a cross made on September 1, 1980 between
'Diamond Jubilee' and 'Paradise Pink'. It is:
-
an attractive red-green, medium-sized obake about 7 l/2'' long and
7 l/2'' wide.
-
a vigorous grower, producing about 6 flowers per plant per year.
-
has a spathe is carried on long flower stems well above the foliage.
-
is resistant to anthracnose and tolerant to the systemic phase of
bacterial blight (Table 1a).
An application for patenting
'Kalapana' was made to the Commissioner of Patents and Trademarks in Washington
D.C. on May 31, 1991, and the patent was approved on March 9, 1993. Subsequently,
the Office of Technology Transfer and Economic Development, University of
Hawaii, executed a License Agreement with the Hawaii Anthurium Industry
Association on January 31, 1994 to propagate and distribute 'Kalapana'
to anthurium growers for commercial use.
Table 1a. Characteristics of 'Kalapana' Anthurium. 
Characteristics 'Kalapana'
Spathe
Size and Shape Broad heart-shaped obake, 7" long, 7" wide,
lobes touching slightly, carried 70-90°
from peduncle.
Color Red (RHSCC* 45C) with green lobes.
Spadix
Size and Shape 2-3/4" long, 1/2" in diameter, curved
downward.
Color Yellow-orange to orange-red.
Anthracnose Resistant.
Flower Stem Long & erect, carrying the spathe well
above the foliage, about 25" long, 1/4" in
diameter.
Yield 6.0 flowers per year.
Vase Life** 20.5 days.
Leaf
Blade Heart-shape, 13" long, 7" wide.
Petiole 20" long.
Internode Intermediate.
Sucker Production High.
Bacterial Blight Tolerant.
* Royal Horticultural Society Colour Chart.
**Includes 3 days of simulated packing.
'Tropic Ice' (UH1051)
'Tropic Ice' (UH1051)
was selected on February 27, 1979 from a cross made on March 16, 1976 between
'Anuenue' and UH515. Its characteristics are described in Table 1b. It is:
-
an attractive white-green, small-sized obake with vase life of about
42 days.
-
is compact with small leaves and produces about 9 flowers per plant
per year.
-
has a spathe carried on a straight peduncle well above the foliage.
'Tropic Ice' is especially
desirable because of its high yield, excellent vase life, resistance to
anthracnose, and tolerance to bacterial blight. It also makes an attractive
flowering potted plant. Mother flasks of micropropagated 'Tropic Ice' were
rele ased to the Hawaii Anthurium Industry Association in 1989 concurrently
with the initiation of advanced testing with cooperating growers.
Table 1b. Characteristics of 'Tropic Ice' Anthurium.
Characteristics 'Tropic Ice'
Spathe
Size and Shape About 6" long, 4 1/2" wide, open lobes,
carried about 90° from peduncle.
Color White with green usually restricted to the
periphery.
Spadix
Size and Shape 2" long, 3/8" in diameter, curved
downward.
Color Yellow.
Anthracnose Resistant.
Flower Stem 15" long, erect, carrying the spathe well
above the foliage.
Yield 8.7 flowers per year.
Vase Life** 41.8 days.
Leaf
Blade Heart-shape, 7" long, 4" wide, leathery.
Petiole 12" long.
Internode Short.
Sucker Production Moderate.
Bacterial Blight Tolerant.
* Royal Horticultural Society Colour Chart.
**Includes 3 days of simulated packing.
'Tropic Mist' (UH780)
UH780 was selected
on January 16, 1978 from a cross made on January 29, 1975 between 'Manoa
Mist' and 'Sea Pearl'. Due to the lack of suitable white cultivars for commercial
cropping, we decided in January, 1984 to place UH780 in tissue culture for
advanc e testing with cooperating growers.
In 1987 plantlets
were sent to the University Experiment Station in Waiakea. At the same time
some cultures in flasks were "early released" to the Hawaii Anthurium Industry
Association. Plants in individual pots were transferred to cooperating growers
in March 1990 for observation and evaluation. Finally in 1993 the tests
were terminated and the selection was named 'Tropic Mist'.
The characteristics
of 'Tropic Mist' are given in Table 1c. Distinctive features are the round
cream-colored spathe carried at 30° to 45° from the flower stem.
Due to the vertical orientation of the spathe, flowers escape damage from
rain and al so may be packed densely.
Table 1c. Characteristics of 'Tropic Mist' Anthurium.
