Uchida2 Departments of 1Tropical Plant and Soil Sciences and 2Plant and Environmental Protection Sciences ‘‘Apapane’ and ‘‘I‘iwi’ are two new cut-flower varieties bred from the University of Hawai‘i patented variety ‘Tropic Fire.’ The bright, glossy red spathes, which are larger and more heart-shaped than those of the ‘Tropic Fire’ parent, bring to mind Hawai‘i’s colorful indigenous endangered birds, ‘apapane and ‘i‘iwi.‘‘Apapane’ (UH1651) and ‘‘I‘iwi’ (UH1679) are siblings selected in July 1992 from a cross between an orangeselection, UH931, and ‘Tropic Fire.’ ‘‘I‘iwi’ was placed in tissue culture in April 1997, while ‘‘Apapane’ followed Fig. 1. ‘‘Apapane’ (UH1651). in October 2000. Both grew rapidly in culture. Tissue-cultured plantlets in flasks were transferred to cooperators in December 2002, while larger-sized plants were sent to one cooperator in July 2004. Vase-life evaluations were concluded in December 2007. Both selections performed well at the advanced test sites in East Hawai‘i. Characteristics of each variety are listed in Table 1. ‘‘Apapane’ appears tolerant to bacterial blight and is resistant to anthracnose. It has a yield potential of 7.9 flowers per year. Its spathes lend themselves to compres-sion when shipped. ‘‘I‘iwi’ has a more elongated and cupped spathe than ‘‘Apapane.’ It is also tolerant to bacterial blight and is moderately resistant to anthracnose. It has a yield poten-tial of about 7.6 flowers per year. Drawbacks of ‘‘I‘iwi’ include the occasional cupping and notching of spathes. Fig. 2. ‘‘I‘iwi’ (UH1679). One cooperator observed vog damage on the upper lobes of ‘‘I‘iwi’s’ leaves. These symptoms mimic pesticide phytotoxicity. Less than 10% of the plants were affected.‘‘Apapane’ and ‘‘I‘iwi’ can be considered for interi-orscape specimens because of their vibrantly colored spathes. Mother flasks of propagules will be delivered to the Hawaiian Anthurium Industry Association in 2011.
