Breeding Strategy of Acacia auriculiformis for Wood Energy

ABSTRACT

Increasing price of unrenewable energy from fossil fuels have directed human kind to find alternatives of renewable energy sources inculding from wood. Multi-funcional species planted mixtured with other species in local garden or as monoculture, and suitable to be grown in less fertile or unused lands is needed. Acacia auriculiformis, a fast growing species planted widely in Indonesia, has those characters. Its high caloric value (4.78-5.11 Kcal/kg) as wood-energy and (7,180-7,322 cal/g) as charcoal has driven breeding for this species for wood energy. Short 4-5 year rotation has been recorded with 24,500 kg/ha dry wood-energy. It‘s mean annual increment at 5 years is between 6.7-19.9 m3 (2,222 trees/ha). This provides promising opportunities to improve biomass and wood energy characters through a series of improvement program. Breeding strategy of A. auriculiformis is therefore planned and aimed to obtain improved growth and improved caloric value. For this purpose, progeny tests F2 involving selected individuals for growth from F1 progeny test have been established in 2 sites. Selected individuals with best characters will be further used as materials for propagation population, either by cloning or by seeds. Infusion by involving material genetic from Indonesia and North Territory are are therefore crucial.
