| Abstract: | Based on the measurements of eight-year-old test plantation of paulownia, the juvenile-mature correlations of height,diameter and volume were analysed by means of rank correlation, genetic correlation and phen-otype correlation. The linear regression equation of the juvenile-mature correlation was set up and the annual efficiency at different selection age was calculated. The results show that the early selection of superior paulownia clones is feasible and the expression of paulownia clones at the age of three could be used to predict the growth of clones at the age of ten to fifteen. Therefore, it is possible to select good clones when they are three years old. |
