摘　　要：对在山西省7个市(县)以速生、丰产选育目标,通过初选、复选,选出速生、产量高、品质好、抗逆性强、病虫害少的白蜡优树50株,通过对这50株优树在襄汾基地进行苗期试验,结果表明:各优树无性系地径和树高差异达极显著水平,苗期选择出优良无性系32个。Taking fast-growth&high-yield as goal,research group selected 50 select trees in seven cities in Shanxi Province from 2007 to 2010.Superior clones of Fraxinus chinensis were selected by testing the indexes of seedling height,ground diameter in Xiangfen Experimental Base.Result shows that there are significant differences in each of height&ground diameter,and 32 superior clones of Fraxinus chinensis were selected in the seedling stage.
