Abstract: 100kg seeds of Taxodium mucronatum Ten. of eastern Mexico were introduced to Wujiang City Nursery Co., Ltd in 2000, and a population of 100000 seedlings was established next year. In 2003,983 plus trees were selected from it based on the individual investigation of growth and crown characteristics, among which, 837 plus trees were selected for their merit of fast growing, 78 trees for their unique crown, and 48 for their golden leaves. The selection differential (S) of basal diameter (D) and height (H) were 0.84 cm and 56.78cm respectively, the selection intensity (I) of D and H were 1.5 and 1.89 respectively. On the whole, a conclusion could be drawn that vegetative propagation could be easily realized due to their high survival percentage (86% for cuttings and 95% for transplants), whereas a significant variation of survival ratio among clones was found.
