比利时 BetterBuxus 抗病黄杨网站 – 黄杨抗病杂交品种信息门户

黄杨真菌病背景与育种计划起点

黄杨属真菌病（Calonectria pseudonaviculata，旧名 Cylindrocladium）过去十几年在欧洲蔓延速度很快，单靠常规杀菌剂越来越难控制，景观公司和历史花园都明显感受到了压力。为了找到可持续的解决方案，比利时 Herplant 苗圃于 2007 年启动了一个与 ILVO（佛兰德斯农业、渔业与食品研究所）合作开展的黄杨育种计划，目标是借助传统杂交和 DNA 研究把抗病基因稳定下来。

Herplant 苗圃四十年基础与 DNA 研究

Herplant BVBA 是一家专门栽培黄杨和红豆杉的苗圃，1985 年由 Hermans 三兄弟 Didier、Louis、Luc 共同创立，公司自 1990 年代初开始专注这两类植物。在启动育种计划之前，Herplant 已经从欧洲植物园和世界各地黄杨收集者手中汇集了 200 多个种和栽培品种，并对每一种的生长速度、抗寒性、叶色、叶形、冬色、抗病性等做了详细记录，为后续的杂交组合提供了基础数据。

四款抗病杂交品种与欧植权保护

育种团队对成千上万株杂交幼苗进行了接种鉴定和田间复筛，最终留下 4 个抗性稳定、长势各异的杂交种，分别命名为 Buxus Renaissance（HER2009B01）、Buxus Babylon Beauty（HER2010B04）、Buxus Heritage（HER2010B02）和 Buxus Skylight（HER2009B03），共同使用 BetterBuxus® 品牌对外推广。这 4 个新品种都已在欧盟植物育种者权利（CPVO）登记，未经许可不得自行繁育，前几年由 Herplant 独家掌控生产。

专属经销商网络与历史花园应用

BetterBuxus® 品种并不进入自由市场销售，而是按国家挑选独家经销商负责推广，目前已在比利时、卢森堡、荷兰、德国、法国、英国、爱尔兰、瑞典、奥地利、瑞士、丹麦、挪威、波兰、意大利等十余个国家建立分销点，Arboretum Kalmthout 等专业机构也在名单之中。截至公开统计，已有 50 多座历史或精品花园把 BetterBuxus® 用于替代老化的感病黄杨，例如城堡花园、修道院绿地和公共绿雕项目。

减少杀菌剂依赖与品牌延伸

BetterBuxus® 的核心卖点是把杀菌剂的使用降到最低限度，让家庭花园、公园绿地和历史园林都能以更环保的方式维护黄杨造型。公司还配套建设了面向养护者的黄杨栽培资料网站 buxuscare.com，提供修剪、施肥、栽种和病害识别等内容。Herplant 也明确表示抗病育种仍在继续，希望未来还能推出适应性更强的新一代杂交品种。

Boxwood Blight and the Start of a Breeding Programme

Boxwood blight, caused by Calonectria pseudonaviculata (formerly Cylindrocladium), has become a steadily worsening problem across European gardens over the past decade, and conventional fungicide regimes alone are no longer enough to keep historic plantings clean. To find a more durable answer, the Belgian nursery Herplant began a boxwood breeding programme in 2007 together with ILVO, the Flanders Research Institute for Agriculture, Fisheries and Food, with classical crosses backed by DNA research to stabilise disease resistance.

Four Decades of Herplant and a DNA-based Collection

Herplant BVBA is a specialist nursery for Buxus and Taxus, founded in 1985 by the three Hermans brothers Didier, Louis and Luc, and has been focused on them as a nursery stock since the early 1990s. Before launching the programme the team had already assembled more than 200 Buxus species and cultivars, drawing on material from European botanical gardens and boxwood collectors around the world, and had mapped growth rate, hardiness, leaf colour, leaf shape, winter colour and disease response for every entry to inform later hybrid combinations.

Four Resistant Hybrids and European Plant Breeders’ Rights

Tens of thousands of hybrid seedlings were inoculated with fungal spores and screened in the field, and only four stable, well-performing crosses were kept: Buxus Renaissance (HER2009B01), Buxus Babylon Beauty (HER2010B04), Buxus Heritage (HER2010B02) and Buxus Skylight (HER2009B03), all marketed under the BetterBuxus® brand. All four are registered for European plant breeders’ rights (CPVO) and may not be propagated without permission, with Herplant keeping full control of production for the first few years.

An Exclusive Distributor Network and Historic Garden Use

BetterBuxus® plants are not sold on the open market and are instead distributed through a network of exclusive partners that has so far been built up in Belgium, Luxembourg, the Netherlands, Germany, France, the United Kingdom, Ireland, Sweden, Austria, Switzerland, Denmark, Norway and Poland, with specialist names such as Arboretum Kalmthout included. According to the programme’s own figures, more than 50 historic or premium gardens have already replaced older, susceptible boxwood with BetterBuxus® hybrids in hedges, parterres, topiary and public green projects.

Reducing Fungicide Use and Continuing Research

The central promise of BetterBuxus® is that fungicide use can be reduced to a minimum, which makes boxwood shaping more workable again for private gardens, public green spaces and historic landscapes. The company runs buxuscare.com as a side project aimed at gardeners and grounds staff, with practical notes on pruning, feeding, planting and disease recognition. Herplant also states openly that the breeding work is continuing and that further, more adaptable hybrids are being worked on for the next round of releases.
