Abstract: The developments in the field of biotechnology have advanced to a stage where its benefits can be apparent in the field of forestry. The ability to manipulate forest tree species at the cellular and molecular levels holds promise for circumventing inherent limitations in tree improvement programs, e.g., long generation cycles, space for large segregating populations, and the lack of genetically pure lines. Genetic engineering methods complement plant breeding efforts by increasing the diversity of genes and germplasm available for incorporation into desirable plant species, and shortening the time period required for the production of new varieties and hybrids. Future developments in the areas of molecular markers and efficient regeneration methods would help in ameliorating the dilemmas of several existing silvicultural practices. The   present article focusses on the first generation applications of genetic engineering of trees, i.e., pest resistance, disease resistance and herbicide tolerance, and discusses the significant progress made in the fields of lignin modification and other traits currently being prospected for genetic manipulation.
