【目的】为了丰富我国榧树(Torreya grandis)品种资源,选育兼具授粉功能和观赏价值的雄性榧树品种。【方法】从雄性榧树实生树中选育获得变异单株,并对其无性系后代进行DUS测试。【结果】选育的榧树新品种‘樉榧’(T. grandis‘Shangfei’)树干粗矮,枝条节间短,叶长1.5~2.5 cm,宽0.27~0.36 cm,叶厚0.50~0.85 mm,叶片开张角度60°~120°。【结论】‘樉榧’株型紧凑、叶片浓密,花粉量大,适宜作为授粉树。

【Objective】To enhance the genetic diversity of Torreya grandis in China, a male T. grandis variety with dual pollination and ornamental value was selectively bred.【Method】A variant individual was selected from male T. grandis seedlings, and its asexual progeny underwent DUS testing.【Result】The newly bred T. grandis variety ‘Shangfei’ exhibited characteristics such as a stout and short trunk, short internodes, leaves measuring 1.5 to 2.5 cm in length, 0.27 to 0.36 cm in width, 0.50 to 0.85 mm in thickness, and leaf angles of approximately 60° to 120°.【Conclusion】‘Shangfei’ features a compact plant shape and dense foliage, with abundant pollen production, making it suitable for landscaping and pollination.
