2个陇南大红袍花椒无刺优树无性系对比研究

Comparison of two superior prickless clones of Longnan Dahongpao in Zanthoxylum bungeanum

为给花椒新品种选育提供试验依据,选取‘武选2号’‘武选3号’2个无刺优树嫁接繁育的无性系作为试验对象,与原品种‘大红袍’在物候期、植物学性状、叶片表型性状、果实表型性状及经济性状、皮刺表型性状等方面进行对照试验,结果表明:2个优树无性系其物候期、叶片表型性状、果实表型性状与对照基本一致,且皮刺明显减少,能够提早丰产,选育前景广阔。

In order to provide theoretical support for selecting and breeding new cultivars of Zanthoxylum bungeanum, using two clones ‘Wuxuan No.2＇ and ‘Wuxuan No.3＇ bred by grafting superior prickless trees as study objects, some characteristics were compared with the original cultivar‘Dahongpao＇, including phenological period, botanical characteristics, leaf phenotypic characteristics, fruit phenotypic and economic characteristics, prickle phenotypic characteristics, and so on. The results showed that the two clones had basically the same phenological phase, leaf phenotypic characteristics and fruit phenotypic characteristics as the control, but the two clones had fewer prickles and could achieve high yield in advance, thus they had a broad breeding prospect.
