在参试无性系与地点互作方差分析、差异显著性检验基础上，对无性系的生态稳定性和综合表现进行了评价，确定８３００２、８４０２３是两个高产、稳产无性系，６年生主干材积与Ａ０５比遗传增益为２３７％—４６０％，与８０４８比遗传增益为２０７％—３２４％。另外还确定了各地适宜发展的无性系 Based on the analysis of the variance of the interaction between clones and sites and the test of significant difference, the ecological stability and comprehensive performance of the clones were evaluated. It was determined that 83002 and 84023 were two clones with high yield and stable yield, Compared with A05, the genetic gain was 237% -460%, while the genetic gain with 8048 was 207% -324%. In addition, it has also identified clones suitable for development everywhere
