引进用美洲黑杨种内杂交（I－69XI－63杨）选育出的中驻1号等新品种25个；用美洲黑杨X欧洲黑杨（I－69X欧洲黑杨）种间杂交的新品种205等，派间杂交即黑杨派X青杨派（I－69X小叶杨）选育出的105等新品种共12个，进行品种对比育苗试验及造纸特性分析．通过综合测试筛选出苗期表现较好的品种，它们的平均材积超亲率（对照）4％～63％，扦插成活率80％以上，木材理化性状达到造纸标准且抗性较强．
In this study, 25 new Zhongzhu 1 cultivars were selected by intraspecific hybridization with Populus tomentosa (I-69XI-63), and 25 new hybrids New variety 205 and so on. The crossbreed crosses 12 new varieties (105) bred by Black Poplar X Qingyang School (I-69X Populus × euphratica), and compared their seedling raising test and papermaking characteristics. Through the comprehensive testing, the varieties with better performance at seedling stage were screened, their average progeny rate (control) was 4% -63%, and the cutting survival rate was 80%. The physical and chemical properties of wood reached the standard of paper making and resistance.
