Abstract
The scarcity of information about the distribution and phenology of superior mother trees is a major constraint in scaling up the production of high quality seedlings of native timber trees in the Philippines. There is also a lack of knowledge among seedling producers and seed collectors about the ideal characteristics of superior mother trees resulting in the collection of germplasm from low quality sources. A survey to identify the location and phenology and to assess the phenotypic quality of mother trees of native timber species on Leyte Island was carried out as part of the implementation of the ACIAR Q-Seedling Project. A similar survey was also undertaken in Southern Mindanao as an offshoot of the Q-seedling project implementation and to support the reforestation program of Sagittarius Mines Incorporated. Locations of mother trees were recorded using a global positioning system and phenologies were determined through local knowledge of seedling producers and available literature. Phenotypic quality was assessed using the method developed by the Department of Environment and Natural Resources. On Leyte Island, 502 mother trees belonging to 32 species were identified. However, almost half of the identified mother trees were of low physical quality, with bent, forking and eccentric stems. In Southern Mindanao, 763 trees belonging to 117 species were identified from the natural forest and on-farm sites. There is a need for an information campaign on the importance of germplasm quality and capacity building to encourage seedling producers to adopt the germplasm collection protocol to increase the collection and use of high quality germplasm. There is also a need to design an efficient germplasm collection and distribution mechanism to improve the availability of high quality germplasm from a wide species base. The implementation of a forest nursery accreditation policy requiring the use of germplasm from superior mother trees will provide financial benefits to tree owners and communities, and thus promote the protection of the identified superior mother trees.
