Abstract: E.Dunnii is a fast growing and cold-tolerant speciesand its wood can be used for pulpwood and sawn timber. It is a species that is difficult for clonal propagation, but has also no blooming and fruit setting in many regions of Chinaand even 13-year old seed trees in orchards in Guangxi and Hunan have not produced seed. By now E.Dunnii seed must be imported with high costs, which haslimitedits development in China. 107 families of 15 provenances have been arranged inrandomly chosen block design. 30 families are selected primitively following the longitudinal growth of 11-months old, 52, 29, 35, 87, 94, 104, 86, 90, 76 and 101 are at the front of the 30 families ranking, and their average tree height is 2.17 meters. There are five elite provenances, namely17915, 17909. 17911, 17914 and 18758, their average tree height is 2.39 meters. The result of this experiment has provided the preliminary basis for the establishment of E.Dunnii seed orchard.
