摘要
经１１年研究，从毛泡桐（陕西周至）×白花泡桐（湖北黄岗）杂交组合的Ｆ１中，选育出了陕桐３号和陕桐４号两个优良无性系。其主要特点是速生、材质好、抗性强。７年生对比林中陕桐３号材积比对照豫杂１号大４７．６％，陕桐４号比豫杂１号大６３．７％。陕桐３号木材力学性质显著优于豫杂１号，抗旱性中等，感病性与豫杂１号接近；陕桐４号抗旱性显著优于豫杂１号，木材材性与豫杂１号接近。
Through 11 Years' study, Shaantong No. 3 and Shaantong No. 4, two superior clonesof Paulownia, were selected from the bybreds of first generation of artificial cross-breeding betweenPaulownia tomentosa and P. fortunel. The main characteristics of those 2 clones are fastgrowth, good wood quality and high tolerance to harsh corditions. In 7 years old plantation forcomparison trial, the wood volumes of Shaantong No. 3 and Shaantong No. 4 are 47. 6% and63. 7% higher than that of Yuza No. 1 (control clone) respectively. The wood mechanicalproperties of Shaantong No. 3 is obviously superior to Yuza No. 1. And its ability to resistwitchesbroom disease is similar to that of Yaza No. 1. The wood mechanical properties of Shaantong No.4 is similar to that of Yuza No. 1.
