Abstract

Imbuya (Ocotea porosa Nees et Martius ex. Nees, Lauracea) is a species of Mixed Ombrophylous Forest threatened of extinction that owns a high quality wood for furniture. Embrapa Florestas is performing imbuya seeds collections for establishing a germplasm bank in october, 2004 in the state of Santa Catarina, Brazil. In spite of its importance, studies about variance components as a basis for phenotypic selection of its characteristics don´t exist. Weight and diameter of seeds collected in two Santa Catarina populations (Canoinhas and Caçador districts) were measured. High repeatability and selective accuracy values were obtained (approximately) for the two characteristics. Predicted phenotypic gains were higher for seed weight than seed diameter.
