摘　　要：741、303、106是经过有性杂交选育的优良白杨无性系,在省内外8个试验点4～9年区域试验结果表明,741具有生长快、稳定性强、适应性广的优良特性,303和106在部分地区表现出速生性.改善土壤肥力状况是促进3个无性系速生丰产的重要措施.'741','303','106' are superior white poplar clones which were bred and selected by hybridization.The regional tests at 8 selected sites that were monitored for 4 ~ 9 years show that '741' possesses the advantages of fast growth,high stability and wide adaptability while '303' and '106' possess fast growth in some regions.Improving the fertility of soil is an important measure to promote the growth of clones.
