为扩大日本落叶松的遗传变异幅度,改善中国日本落叶松的育种状况,提高育种水平和林业生产力。对落叶松种和种源、原生种源试验林建成后10 a的数据进行比较,结果表明：日本落叶松次生种源的胸径、树高、单株材积分别是原生种源的1.10,1.11,1.23倍;选育出了13个优良种源,为我省及辐射推广地区营造日本落叶松速生丰产林找到了优良种源。
為擴大日本落葉鬆的遺傳變異幅度,改善中國日本落葉鬆的育種狀況,提高育種水平和林業生產力。對落葉鬆種和種源、原生種源試驗林建成後10 a的數據進行比較,結果錶明：日本落葉鬆次生種源的胸徑、樹高、單株材積分彆是原生種源的1.10,1.11,1.23倍;選育齣瞭13箇優良種源,為我省及輻射推廣地區營造日本落葉鬆速生豐產林找到瞭優良種源。

In order to expand genetic variation range and improve breeding conditions and forestry productivity of Japanese Larch in China,data of primary provenance and secondary provenance collected 10 years after completion of test stand of Japanese larch were compared.The results showed that the DBH,tree height and individual volume of secondary provenance of Japanese Larch were 1.10 times,1.11 times and 1.23 times higher than that of primary provenance respectively.We selected and obtianed 13 superior provenances for Japanese larch plantation in Hubei province and other radiation extension area.
