The national research project “Genetic improvement for some main planting tree species to increase plantation productivity and quality” in the period 2006-2008 was implemented by the Research Centre for Forest Tree Improvement, Forest Science Institute of Vietnam. The overall objective of the project was to improve plantation productivity and quality for some main planting tree species in Vietnam, and contribute to improving stakeholder’s incomes and the competitiveness of the country.The objective was achieved through breeding, testing, selection of the best performing varieties, and releasing them to production via appropriate propagation methods. The project also aimed at maintaining genetic diversity of main planting tree species for future genetic improvement.
In the period 2006-2008, 24 clones of Acacia auriculiformis and four clones of Eucalyptus camaldulensis had been selected from several clonal trials and approved as technologically advanced planting varieties for commercial plantations. The vegetative propagation techniques for approved clones have been developed. In the mean time, 11 seed orchards of Acacias, Eucalypts and Pines were also approved as national seed orchards by the Ministry of Agriculture and Rural Development. The project had also successfully studied genetic control and the level of genetic variation for economically important traits such as growth, wood density and mechanical wood properties at provenance, between and within family levels. We also studied the genetic relationship between traits, and the level of genotype by environmental interaction. This information provide the basis for determining appropriate breeding strategies for different species to maximize genetic gain in the following generations.
From established progeny and clonal trials, we have preliminarily selected some families and clones having good growth and desired wood quality that could be approved and developed into production in the near future.
