摘要
对毛白杨各无性系间的性状表现与遗传差异进行了初步研究,通过方片差分析,遗传参数的估算,找出了毛白杨各无性系间的遗传差异,为早期选择提供了理论根据。
Both character expression and genetic variafions between Populus tomentosa
Carr.clones were studied.Through testing their variance,calculating their gene-
tic parameters and further probing their genetic variations a theoritical founda-
tion for early selection of breeding was provided.At the same time,growth
appearance of various clones was also brought under discussion.
