Genetic variation in height growth and leaf colour in E. deglupta
High levels of additive genetic variance were found in height growth up to 16 months of age in three progeny tests of E. deglupta in Costa Rica.3Heritabilities 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%
