'KALAPANA', 'TROPIC ICE', AND 'TROPIC MIST' ANTHURIUM
Three anthurium selections, UH 1016,UH 1051, and UH780, were named 'Kalapana', 'Tropic Ice', and 'Tropic Mist' respectively. 'Kalapana' repre-sents the first anthurium cultivar to be patented by the University of Hawai'i.

'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 71/2" long and 71/2" wide and a vigorous grower, producing about 6 flowers per plant per year. The spathe is carried on long flower stems well above the foliage. It is resistant to anthrac-nose and tolerant to the systemic phase of bacterial blight (Table 1).
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 Hawai'i, executed a License Agreement with the Hawai'i Anthurium Industry Association on January 31, 1994 to propagate and distribute 'Kalapana' to anthurium growers for commercial use.

'Tropic Ice' (UH1051)
'Tropic Ice' (UH 1051) was selected on February 27, 1979 from a cross made on March 16, 1976 between 'Anuenue' and UH515. Its characteristics are described in Table 1. It is an attractive white-green, small-sized obake with vase life of about 42 days. The plant is compact with small leaves and produces about 9 flowers per plant per year. The spathe is 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 released to the Hawai'i Anthurium Industry Association in 1989 concurrently with the initiation of advanced testing with cooperating growers.

'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 advance testing with cooperat-ing 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 1. 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 also may be packed densely.
