台灣耐熱及抗煙草嵌紋毒素病小番茄之育成

The Development of Heat-Tolerant and Tobacco Mosaic Virus (TMV) Resistant Cherry Tomatoes in Taiwan

亞洲蔬菜研究發展中心經二年的試驗，選出兩個優良的雜交一代小番茄PT912和PT913，其產量、耐熱性和抗煙草嵌紋毒病均比地方栽培種金柑及雜交一代農友209為佳；此二雜交一代品種在早秋不噴荷爾蒙的自然狀況下栽培，具商品價值的產量每公頃達70公噸以上。結果顯示利用雜交一代品種以組合耐熱抗病及較好的園藝性狀，乃是有效的育種方法。

After two years' trial, two hybrid selections, PT912 and PT913 developed at the Asian Vegetable Research and Development Center (AVRDC) were identified to be superior to the commonly grown local cultivars, Golden Citrus and Known You 209 F, in terms of yield, resistance to heat and Tobacco Mosaic Virus. These two selections produced up to 70 t/ha of marketable fruits in early fall under natural conditions without the need of hormone treatment. Results in these trials suggested that the development of F1 cultivars is an efficient method to combine resistance to heat and diseases with better horticultural traits.
