摘要
引种日本落叶松原生种源及优树半同胞家系苗期试验研究结果表明：原生种源问高生长具有明显差异，确定松本、伊那、日光为优良种源；家系间的高生长也具有明显差异，确定县诹访１号等２０个家系为优良家系；原生种源的遗传变异幅度极大，具有相当的遗传改良潜力和遗传资源保存价值。
The growht of different provenance and half-sib families of plus trees of Larix kagempferi comes from Japan were significantly different. The results show that provenance of matsumoto,ina,niko are superior provenance for Hubei province,and that 20 half-sib families of plus trees had been selected as superior families. It can be regarded that original provenance have big range in genetic variety,and have potential of genetic improvement and reserveation value.
