Abstract
Results of three progeny tests of Eucalyptus deglupta in Costa Rica are described and discussed. High levels of additive genetic variation were found in height growth up to 16 months. Heritabilities were within the range typically found in forest trees. High levels of additive genetic variation and family heritabilities in leaf colour were also found. Purple leaves were associated with slow growth, and green leaves with fast growth. The best families showed a high degree of stability across the three sites. Predicted genetic gain from directed seed collections of the best mother-trees ranged from 12.4 to 15.8%. © 1995.

The leaf colour assessments were made by Marvin Hernandez (CATIE). The contributions of Victor Alvarado, Oldemar Baeza, Vanessa Bainbridge, Ger-ardo Barquero, Carlos Castro, Jose Ma&, Jose-Angel Quiros and Luis Sanchez (all CATE) are also gratefully acknowledged, as are those of landowners Armando Bustamente, Harry Carranza and Los Nacientes S.A. The authors thank the British Overseas Development Administration and the Norwegian Ministry of Foreign Affairs for their financial support, and Drs. Jose Joaquin Campos (CATIE!) and Bryan Fine-gan (CATIE) for their useful comments on the final draft.
