Abstract

By taking 30 half-sib progenies from plus trees of Phoebe zhennan as studying objects, the seedling height, basal diameter and the length of new shoot of 1.5-year-old seedlings were investigated and studied in order to provide a reference for the genetic modification and the selection of improved variety. The results indicated that there were highly significant difference between families in the three traits of seedling height, basal diameter and the length of new shoot, also the three traits were highly under genetic control and significantly correlated among them. Considering the seedling height and basal diameter, 6 half-sib progenies which seedling grew quickly were preliminaryly screened out, and the Gusi no.2 was the best.
