Abstract
近年來，番茄捲葉病 (Tomato leaf curl disease, TLCD) 對番茄產業造成嚴重衝擊，導致作物產量與品質大幅下降，而選育具抗性基因之品種被認為是最有效直接的防治途徑。本研究利用Ty-2 及Ty-3 分子標誌，調查國內104 個優良雜交F1 小果番茄品種，結果顯示有84 個品種至少帶有Ty-2 或Ty-3 抗病基因，占總量81%，顯示國內具抗病性的商業品種選擇眾多，惟農民對於各抗病品種的實際表現缺少種植經驗與驗證。後續進一步於溫室及露天田區試作評估，品種 ‘玉女’ 未帶任何番茄捲葉病抗病基因，其病毒感染率較高且病徵明顯；而於露天田區，大多數帶有抗病基因之品種展現良好抗病性，整體田區感染番茄捲葉病之情形輕微，顯示抗病品種具有進一步應用與推廣價值。
In recent years, tomato leaf curl disease has caused severe impacts on the tomato industry, leading to substantial reductions in yield and fruit quality. Breeding tomato cultivars with resistance genes is considered the most effective and direct control strategy. In this study, Ty-2 and Ty-3 molecular markers were used to screen 104 domestic F1 hybrid cherry tomato cultivars. The results showed that 84 cultivars (81%) carried at least one of the resistance genes Ty-2 or Ty-3, indicating that diverse commercial resistant cultivars are available in Taiwan. However, growers generally lack cultivation experience and on-farm verification of the actual performance of these resistant cultivars. Subsequent evaluations were conducted under greenhouse and open-field conditions. The cultivar ‘Rosada’, which has neither Ty-2 nor Ty-3, exhibited a higher infection rate and more severe symptoms. In contrast, in open-field trials, most cultivars with resistance genes showed high resistance, and the overall incidence of TYLCV was low. These results highlight the potential value of resistant cultivars for further application and promotion in tomato production.
