Abstract

Three new varieties of Hoya were registered to the Germplasm and Technology Release and Registration Office of the Institute of Plant Breeding, College of Agriculture and Food Science, University of the Philippines Los Baños and the National Seed Industry Council, Bureau of Plant Industry, Department of Agriculture in 2020 and 2023, respectively. These are open-pollinated (OP) segregants of Hoya ilagiorum (Kloppenburg, Siar & Cajano) that were generated in 2010. Evaluation of OP seedlings started in 2012 and the selection of promising segregants yielded 3 varieties, namely ‘Moonlight’, ‘Sunkissed’, and ‘Starburst’. ‘Moonlight’ has a dainty creamy yellow inflorescence consisting of 31 to 112 individual flowers forming a semi-globose to globose umbel akin to a full moon during anthesis, thus the name. ‘Sunkissed’, with its striking leaves, also has a semi-globose to globose umbel composed of 37 to 73 individual flowers, each with a shiny and highly reflexed corolla in varying shades of yellow with brownish-pink edges. ‘Starburst’ has 21 to 81 individual flowers forming a semi-globose umbel. The corolla has 2 color combinations that are visible even prior to flower opening — the principal color is creamy yellow with a thick, reddish outline along the edges of the lobes, forming a band-like pattern. These are the first varieties under the genus Hoya that are officially registered in the Philippines.
