摘要

In order to enhance productivity of planted forests in a short period, it is essential to adopt tools of genetic improvement followed by commercial deployment of improved planting material to harness maximum gain. The improved planting stock will not only increase the growth and productivity but will also influence survival, disease resistance and wood quality. The existing variation in the wild plays a crucial role in screening trees with desirable characteristics, as it is the platform for other components of the improvement cycle, namely breeding populations, propagation populations and production populations. One of the most important strategies would therefore be to deploy only commercial clones in production populations for increasing productivity and economic gain. The approaches of genetic evaluation and testing will be of immense use in the operationalization of commercial forestry. It is essential to subject the selected germplasm to multilocation testing (MLT) before deploying them in commercial forestry to ensure high adaptability and productivity.
