| 年度 | 2014 耐濕冷馬鈴薯品種選育 Wet and cold resistant breeding for potato 103農科-14.1.2-種-X1 103AS -14.1.2-SS-X1 品種改良保護課 Plant Breeding Section 張勝智 Sheng-Chih Chang 1. 異常的氣候，常是造成農民栽培作物歉收的主要原因之一。近幾年的氣候變遷，尤其是溫度與雨量的變化，均間接或直接造成生產的損失。馬鈴薯在台灣主要於冬季種植，但近年來的異常氣候，如低溫與多雨的異常氣候，常伴隨發生，導致馬鈴薯植株更易腐敗且多種病害發生嚴重，尤其是大規模晚疫病所造成的減產問題，故栽培者常需噴濕大量農藥防治與增加管理負擔，除影響農民收益外，更造成生產成本增加、食物安全與市場價格波動劇烈等問題，造成嚴重影響。因此為改善低溫高濕造成的多種問題，故以品種改良為目標，針對本場經多年選育具優良生長勢、產量與品質的48個營養系，進行低溫高濕的汰選評估。2. 經100/101年期的汰選，初選出11個具耐濕與高產生育特性的營養系(628、474、470、91A179、320、183、578、91N80、317、T75、462)，並於101/102年期持續汰選出5個分別(營養系470、628、91N80、320、462)具耐濕冷、生長勢強與高產，並具有中高耐病性(耐晚疫病)等特性之營養系，於102/103年再汰選評估出最優的3個營養系，分別為628、470與320，準備於103/104年期進行性狀調查，挑選表現最佳的營養系供作未來因應低溫高濕氣候的應用品種，期許能協助種苗業者克服因異常環境造成的減產與過量用藥等，所造成的食物安全與農民健康等問題。 1. Abnormal climate is often one of the main causes of farmers planting the crop failure. In recent years |
| 計畫名稱_中文 | climate change |
| 計畫名稱_英文 | the production of crops were especially caused loss by temperature and rainfall changing.Potato was mainly planted in winter in Taiwan. Anomalous Climate in recent years |
| 計畫編號_中文 | such as low temperature of climate anomalies was often associated with rainy. Those factors leaded to the potato corruption and induced more diseases. Especially large-scale production problems caused by late blight |
| 計畫編號_英文 | so growers often need to spraying pesticides to control and increase the burden. In addition to affecting farm income |
