'PINK CHAMPAGNE', 'ANDRAECOLA-1', and 'ANDRAECOLA-2' ANTHURIUM

In 1991 we released two cultivars, 'Misty Pink' and 'Pink Elf', that originated from a cross between 711-13 (Anthurium andraeanum 'Uniwai' x A. Iindenianum) and the miniature lavender species, A. amnicola (Acc. 417). Like most hybrids of A. amnicola, the two cultivars were heavy producers of relatively small pink flowers.

'Pink Champagne', 'Andraecola-l', and 'Andraecola-2' are also hybrids involving A. amnicola. The small pink and red flowers of these cultivars should provide additional novel anthurium flowers for the commercial cut flower trade.

• 'Pink Champagne' (UH1149)
• 'Andraecola-1' (UH1208) and 'Andraecola-2' (UH1228)

'Pink Champagne' (UH1149)

This cultivar originated from a cross made on April 30, 1983 between 'Anuenue' and A. amnicola. The seedling, UH1149, was selected on May 21, 1987. Its characteristics are shown in Table 2a.

It was placed in tissue culture for advance testing in 1989. Plantlets were transported to the University Experiment Station in Hilo in 1991, and plants in individual pots were transferred to cooperating growers for advanced testing in 1993. A few floweri ng plants observed earlier at two locations showed promising results, therefore, UH1149 was named 'Pink Champagne'.

• 'Pink Champagne' has attractive pink flowers that are broader than 'Misty Pink'.
• Vase life of about 20 days (in an air conditioned room at about 70°F) is acceptable for a hybrid of A. amnicola.
• It gives a high yield of about 8.2 flowers per flowering stem per year.
• A weakness might be the relatively long internodes probably inherited from the 'Anuenue' parent.

'Andraecola-l' (UH1208) and 'Andraecola-2' (UH1228)

'Andraecola-l' and 'Andraecola-2' are siblings from a cross made on October 26, 1983 between A. andraeanum (Acc. 481), collected by Dr. Michael Madison in Ecuador, and A. amnicola (Acc. 417). UH1208 was selected on November 30, 1988 and UH12 28 on April 4, 1989. After several years of observation and evaluation at the Mauka Manoa Campus, we concluded that both should be elevated to advanced testing. We, therefore, placed both in tissue culture in 1993. We named them 'Andraecola-l ' and 'Andra ecola-2' combining Andrae from A. andraeanum and cola from A. amnicola.

The characteristics of both 'Andraecola-l' and 'Andraecola-2 are similar, and so only those of 'Andraecola-l' are presented in Table 2b.

Major characteristics of the two are:

• 'Andraecola-1' produces much longer flower stems, but the spathe size is slightly smaller.
• Spathe color and shape are similar.
• Both produce over 8 flowers per flowering plant stem per year.
• Vase life of about 21 days for both is slightly better than that of 'Pink Champagne'.
• Bright red spathes of 'Andraecola-1' and 'Andraecola-2' are unique among A. amnicola hybrids.
