Abstract: The provenances of Ulmus pumiea L. can be divided into six provenance regions in China by observating experimental forest for 8 years. The volume of prorenance breeding value (Z) increased by 150% selecting appropriate provenances. Family selections have been evaluated using selection index (I1), and ecological adaptation movements of provenances by means of ecological adaptation index (q(ij)). Meantime, the heritability stabilities of character and the areas of experimental plot have also been analized in this paper.
