Our goal is to identify and make broadly available ROD-resistant ʻōhiʻa for restoration and landscaping applications across Hawai‘i. To achieve this goal, research is needed in the following areas:
- Improving ʻōhiʻa propagation methods to accelerate the time it takes to get large, healthy ʻōhiʻa.
- Developing disease screening techniques that are accurate and efficient.
- Propagating ‘ōhi‘ā survivor trees on Hawai‘i island from forests heavily impacted by ROD via cuttings and seeds, and inoculating resulting plants with the Ceratocystis pathogens to gauge resistance to ROD.
- Propagating Metrosideros taxa from ‘ōhi‘ā seed bank accessions, and screening resulting plants to assess statewide levels of ROD-resistance.
- Identifying the biochemical profile of ROD-resistant ‘ōhi‘ā, and developing remote sensing technologies to rapidly detect resistant ‘ōhi‘ā in the field.
- Establishment of a network of field sites to assess the roles that climate and environment play in disease resistance, and produce ROD-resistant seed.
- Identifying the mechanisms behind disease resistance, and, if more than one resistance mechanism is present, developing breeding protocols to create progeny with multiple forms of ROD-resistance.
- Developing molecular tools to rapidly screen offspring derived from controlled breedings.
