毛梾种质资源分布及其良种选育繁育研究进展

毛梾(Cornus walteri Wanger)在我国分布范围较广,分布区包括黄河流域、华东及西南部温暖带落叶阔叶混交林区、北亚热带落叶常绿阔叶混交林区和中亚热带常绿落叶阔叶林区。为优良的油料树种和园林绿化树种,具有广阔的开发和利用前景。作者介绍了毛梾的种质资源分布及良种选育繁育技术,以期为今后毛梾的良种选育和生产应用提供参考。

Cornus walteri distributes widely in China, including the Yellow River Basin, eastern and southwesten warm with deciduous broad leaf mixed forest zone, the northern subtropical deciduous mixed with evergreen broad--leaved forest zone and the middle subtropical evergreen mixed with deciduous broad leaf forest zone. Comus walteri has a broad development and utilization prospect as an excellent oil tree and landscape tree. The paper introduced the germplasm resource distribution, selective breeding and multiplication technology of improved material of Comus walteri, in order to provide a reference for fu- ture breeding and production applications of Cornus walteri.
