Résumé : This paper aims to describe the role of tree improvement in addressing constraints to the development of tree planting in 3 types of situation which broadly cover most of the current tree planting in the tropics. In the context of tree planting for household needs, the most important contribution of tree irnprovernent is in the area of species, provenance, family evaluation. More than a 1,000 multi-purpose tree species are cited as being utilised but knowledge to support promotion at farm level is adequate only for a very small number. Where farmers are planting trees to produce raw material for industries, they generally do it as a side activity and their production systems are not very intensive. Improving the genetic quality of the planting stock is generally the first measure farmers are encouraged to take where external support is provided for a shift to more intensive production systems. Such schemes are implemented successfully were industries have a direct concern about regularity and quality of farmers' supply and provide credit, an assured market, equitable pricing system as well as technical support. The role of tree breeding in the development of cost competitive products is nowadays widely acknowledged by industrial plantation managers and there are several examples of success stories of private investment in industrial forest plantation development in the tropics. However, most of these successful ventures between foresters and industrials concern fast growing, short rotation species such as those used in pulpwood industries. Long rotation length will remain an inherent disadvantage where production will be targeted to timber production.
