摘　　要：对１２个泡桐无性系苗期性状测定分析表明，苗高、地径、叶面积和材积指数的遗传力分别为７３．５％，８６．２％，８３．４％和８０．４％；遗传变异系数分别为５．４３％，１１．３％，１２．２％和２６．２％。地径、叶面积和材积指数三个性状间的遗传相关、环境相关和表型相关显著。据此，确定以地径或材积指数作为苗期选择性状，初选出２个较优良的无性系供中试验证。12 clones of Paulownia were analysed in aspect of genetics,its h2 of height,area of leaves, diameter and volume is respectively 73. 5%, 86.2%, 83. 4% and 80. 4%,GCV is 5. 43%, 11. 3%, 12. 2% and 26. 2%. The genotype, phenoypic and environmental correlation were significant among diameter,area of leaves and Volume. The results showed that diameter or volume could be used as a select characteristic, and two clones were selected.
