简要论述了选择育种与实现林业生产良种化的关系，强调表型选择必须进行遗传测定，指出经过无性系测定的优良无性系直接用于生产，是实现生产良种化的捷径
The relationship between selective breeding and seed production of forestry production is briefly discussed. The phenotypic selection must be determined by genetic analysis. It is pointed out that clonal determination of excellent clones is directly used for production, which is a shortcut to the production of improved seed production
