Abstract

Indoor artificial crosses for two groups of Populus deltoides （I-69 and I-57）（female）：I-69 with P. cathayana，P. szechuanica，and P. purdomii（male） and I-57 with P. cathayana and P. szechuanica were carried out in the spring of 2006. Then，in September 2007，growth performance，and infection from Marssonina brunnea fungi on the 1-year-old hybrid seedlings were tested. with a 30 cm×40 cm seedling space design having 10 seedlings per plot and 3 replications using an ANOVA with an LSD test. Results among the five crosses showed that percentage of fruit set and seed germination ranged from 55% to 20% for the I-69 group and 20% to 5% for the I-57 group. Best growth performances were with I-69 × P. szechuanica having a mean hybrid seedling height of 2.87 m and I-69 × P. purdomii（2.38 m） along with root-collar diameters 2.57 and 2.13 cm，respectively. The LSD test also showed that hybrid seedling growth for mean height and root-collar diameter of I-69 was significantly greater（P ＜ 0.01） than the I-57 group. M. brunnea infected 100% of all hybrid seedlings； however，the infection index of the I-69 group was lower. Thus，the I-69 × P. szechuanica，I-69 × P. cathayana，and I-69 × P. purdomii crosses have good resistance to M. brunnea. ［Ch，4 tab. 26 ref.］
