Abstract: In order to study growth superiority of the fine family and provenance of Pinus latteri, 91 families of 4 provenances of P. latteri introduced were investigated in the seeding stage. The seedling height, ground diameter, germination and height-to-diameter ratio of P. latteri were tested. The factors of family and provenance had significant affection on germination rate and ground diameter, the factor of family had significant affection on height-to-diameter ratio, the factor of provenance had significant affection on seedling height. 11 superior families were selected; meanwhile, Family T36 which had a very significant growth variation was found and the relevance of between clustering classification and provenance was studied by the used method of cluster analysis.
