Abstract: Sixty-one Catalpa duclouxii clones, were induced to choose better clones in Dongtai City, Jiangsu Province. Growth indices, such as diameter at breast height (DBH), height (H), were monitored in a Catalpa duclouxii test forest. The range was 1.47-4.55 cm, with the mean of 2.57 cm, for DBH, and 1.44-3.58 m, with mean of 2.27 m for H. 61 clones were clustered to 4 group through cluster analysis, and significantly differences were found among these 4 groups for DBH and H. 040, 36-1, gz-11, yn-031-2, yn-041-5, yn-042-1, yn-1, yn-2, yn-36, 109-1, 142-2 were chose out due to higher DBH and H. These 11 clones could be pay more attention to.
