Abstract
草苺具高經濟性且可多元利用，為全球性的產業。依據行政院農業委員會農業統計資料顯示108 年臺灣的草苺栽培面積達489 公頃，年產值超過13.5 億元。國內的草苺於栽種季節容易受病蟲害的危害而影響其生育與品質，其中草苺病毒病害在國外已有超過20 種的病毒紀錄，依不同病毒種類對草苺的影響而有差異，也常見有感染草苺後不造成病徵，但與其他病毒複合感染時會加劇病徵表現而影響產值；罹染病毒而不表現病徵者，生長勢也會逐漸減弱。因此源頭健康種苗品質管理為重要關鍵，每年更換無特定病原之健康種苗，再配合栽培期間的
病蟲害防治管理，可確保產值。臺灣的草苺病毒病目前僅有草苺輕型黃邊病毒(Strawberry mild yellow edge virus, SMYEV) 的發生紀錄，也有發現受感染株不表現病徵。因此，草苺種苗以組織培養量化，或以營養匍匐莖苗( 走莖苗) 繁殖時，對繁殖用母株之病毒篩檢相當重要。國內已建構有草苺種苗病害驗證體系，SYMEV 被規範為檢定標的之一；透過此驗證體系，可維護國產草苺種苗之健康品質與市場競爭力。
Econamic production of strawberry is a global industry with high value and multiple uses. In 2019, the cultivated area of strawberries in Taiwan was 489 hectares, with an annual output of more than 1.35 billion N.T. dollors. The yield and quality of strawberries were easily affected by the diseases and the pests during growing seasons. More than 20 viruses have been recorded worldwide. The effects of various viruses on strawberry plants are depended on the species of virus.Symptomless virus-infected plants were commonly observed on strawberries, but plants with severe symptoms caused by complex infection with other viruses were also found and that lead to a great yield loss. The symptomless infected strawberry plants were gradually weaken in growth vigour. For ensuring the yield and quality of strawberry production, the appropriate managements of original healthy seedlings are very important, including: the annual replanting of the specific pathogen free seedlings, and combining with the treatments to control the diseases and pests efficiently during the growth stage. Strawberry mild yellow edge virus (SMYEV), the only virus infecting strawberry in Taiwan, was currently reported, in which some SMYEV-infected plants were symptomless. Therefore, the virus indexing on mother stocks is prequisted to mass-propagation program of healthy strawberry seedlings through tissue culture or replication of runner. The strawberry seedling health verification system has been established in Taiwan, and SMYEV is regulated as one of the specific pathogens for indexing. Based on this verification system, the healthy quality of domestic strawberry seedlings can be maintained and to keep the market competitiveness in the world.
