Abstract: A set of the excellent varieties of Sweden short rotation coppice willow(SSRCW) and other ornamental varieties have been introduced from Sweden to China since 2004.About 1.53 hm2 germplasm resource nursery and 2.67 hm2 plantation in Yangling, Huanglong and Qiaoshan in Shannxi province have been established.The survival rate of young branch cutting and old branch cutting is above 90 % in different seasons.The height, diameter, biomass of mean individual of SSRCW is 2-3 times more than that of the native willows species and 4-5 times more than that of other native trees (Hippophae rhamnoides, Quercus variabilis, etc.).There are differences among the clones of SSRCS, the clone C and clone E are the best.The parameters of water relation and enzyme, etc.which show the ability of dry-resistance are 50 % higher than that of the native species.The experiment of cutting, pruning and making shape for SSRCS show its excellent omamentatl characters.These clones of SSRCW can keep the excellent native character in China.

Key words: Sweden short rotation coppice willow (SSRCW), cultivation technology, bioenergy
