Acacia auriculiformis and A.mangium the two fast growing exotic species have been introduced to Bangladesh for meeting the increasing demand offuelwood and poles. During last decade, thousands of hectares of plantation have been raised with these two species. In a number of A. auriculiformis plantations, several outstanding trees have been observed with good growth and vigour. These trees possess many characteristics of both good growth and vigour. These trees possess many characteristics of both A. auriculiformis and A. mangium. The hybrid trees coppice well and are somewhat resistant to heartrot disease in addition to its higher growth rate. The per unit area productivity of this hybrid would be higher than the existing output of either of the parent species. The use of vegetative propagulesrather than seedlings as a commercial forest regeneration method present an opportunity in genetic improvement.
