Abstract

Thls paper analysed the provenance heritability and correlati correlation coefficients of Taiwan pine in annual tree height according to the data from provenance test plantations at the age of 8, with provenance heritability varing from 0.62 to 0.76 and genetic correlation coefficients all being more than 0.82. Ther results howed that tree height increment had a genetic stability with time. The age, 8 to 10, was an optimum stage for the early selection of Taiwan pine stand with a significantly higher genetic gain than that gained in crop time according to the data of stem analysed sample from plantations (aged 28) and natural stands (aged over 45) of Taiwan pine, which was juvenile-mature phenotypic correlation coefficients and the rate of annual genetic gains on early selection.
