| 摘 要： | 通过对大兴安岭林区落叶松初级种子园中的5年生兴安落叶松幼树高生长资料方差分析,结果表明:兴安落叶松家系间存在显著差异,在低强度选择下可以选出30%左右的优良家系,初步估算了用这些中选无性系组建1.5代种子园可带来的遗传增益,并提出了在大兴安岭地区组建落叶松1.5代种子园的设想。

| Abstract: | Through analysis of variance by data of height growth of 5-year-old youngling on junior Larch seed orchard in Daxing'anling,results showed that it existed significant differences in clones of Larix gmelini.About 30% of superior clone could be selected under the selection of low intensity.The hereditary gain,which could be brought from building 1.5-era seed orchard by selecting from these clones,was estimated preliminary.Imagination of building 1.5-era seed orchard of Larch in Daxing'anling region was proposed. |
