摘　　要：采用随机区组设计试验,经过早期选择,对进入新种质备选材料库的7个编织柳新杂种无性系进行了生长性状比较。结果表明:各参试无性系生长进程呈S型曲线,可以用Logistic函数拟合,在南京地区最快生长期为5—8月中旬;方差分析表明,新无性系JW4-5、JW0-5的高生长显著优于其它无性系,平均高生长量分别达150、157 cm,可以作为进一步开展区域试验的新品种。By randomized block design,we tested the growth process of seven new clones as new germplasm material stock. All the tested clones＇ s growing process were in an s-shaped curve,can be fitted by using Logistic function. The fastest grow period in Nanjing area was in the mid-May to mid-August. By the analysis of variance,new clones of JW4-5 and JW0-5was significantly better than the others in height growth,with the top average height of 150 cm and 157 cm,respectively,and can be used as a further variety regional test.
