Abstract: After a follow-up investigation on the test forest of poplar clones for 11 years, seudies were made of the growth indexes of 18 poplar chones such as DBH, tree height and volume and genetic variabilities, and their growth adaptabilities were evaluated comprehensively by principal component analysis for 18 poplar clones in the test forest of Nan'geng Forest Farm at Daguan District of Anqing City. The results showed that there were significant differences in DBH, tree height, volume among different clones.the growth indexes of ‘Jiang Huai 1’ was best, ‘Jiang Huai 1’ was an excellent male poplar clone by ranking first in comprehensive evaluation of growth adaptability, which not only inherited the excellent characteristics of parents, but also had high genetic gain.
