Abstract:

Genetic parameter estimation is one of the most important steps in tree breeding. Tree clonal breeding has many advantages, of which are mainly simple in breeding method, short breeding circle and high gain. But it larcks a good set of methods in genetic parameter estimation. At present, the estimating genetic parameters in clonal breeding of forest trees nearly all adopt the methods used in sexual breeding, which is likely to affect precise estimation of genetic parameters. This paper presents a precise fomula of genetic parameter estimation for clonal breeding after an investigation on clonal materials. A discussion was also made on the number of clones used in the establishment of plantations.

Key words: Clonal material, Genetic parameter, Tree breeding
