Early evaluation on growing traits for open pollination progeny testing from Toona ciliata var.pubescens plus trees

An affforestation trial of Toona ciliata var.pubescens containing 58 families was conducted in Nanling,Anhui Province.The results showed that the differences of these growing characters were significant between families.Variation coefficients of tree height and breast height diameter were 21.1% and 28.8%,respectively.This indicated that the variation in growing traits was very rich.The broad heritability of tree height and breast height diameter was above the middle level.Fast-growing families were selected according to the growing traits of the young forests,they are No.10,No.15,No.19,No.27 and No.39.
