Provenance and family variation in height and diameter growth of Cupressus lusitanica Mill. at 28 months in Costa Rica
Abstract
Results of a provenance / progeny trial of Cupressus lusitanica in Costa Rica are described. At age 28 months, progeny of plus-trees selected primarily for stem straightness and cylindricity had grown significantly faster than three commercial controls and a seedlot produced from a Colombian clonal seed orchard. The estimated values of additive genetic coefficients of variation (10.2% to 15.9%) and heritabilities (0.12 to 0.21) were within the ranges typically found in forest trees. There was no evidence for important differences between the Costa Rican, derived provenances.
