‘闽薯3号’系福建省农业科学院作物研究所以中国农业科学院蔬菜花卉研究所提供的‘Chieftain’ב郑薯6号’杂交组合实生薯,经过在福建省内多年多点鉴定和区域试验选育的冬作马铃薯新品种。该品种生育期90 d。株高47.3 cm,叶片绿色,茎绿色。单株块茎数4.9个,单株薯重0.48 kg,薯形短椭圆,薯皮红色光滑,薯肉中等黄色,红芽眼,芽眼浅,商品薯率83.5%。干物质含量18.16%,淀粉含量13.21%,蛋白质含量1.95%,维生素C含量18.92 mg/100g。中感晚疫病,高抗早疫病,中抗轻花叶病毒病(PVX),抗重花叶病毒病(PVY)。食用品质好。2014~2016年福建省马铃薯区域试验平均鲜薯产量1640 kg/667m^2,较对照‘紫花851’增产6.06%。适宜在福建省冬、春季种植。

A new winter-potato variety,‘Minshu 3’,was selected and bred from the cross of‘Chieftain’בZhengshu 6’,by the Crop Institute,Fujian Academy of Agricultural Sciences after many years of multi-location tests and regional trials in Fujian Province.The seedling tubers were provided by the Institute of Vegetables and Flowers,Chinese Academy of Agricultural Sciences.The growth duration of'Minshu 3'is 90 d,with green leaf,green stem,short ellipse shape tuber,red and smooth skin,medium yellow flesh,and red and shallow eye.The plant height is 47.3 cm,number of tubers per plant 4.9,tuber yield per plant 0.48 kg,and marketable tuber percentage 83.5%.Dry matter content is 18.16%,starch 13.21%,protein 1.95%,and vitamin C 18.92 mg/100g.It is moderately susceptible to late blight,high resistant to early blight,moderately resistant to potato virus X,and resistant to potato virus Y.It has good edible quality.During 2014-2016,it was tested in Fujian Provincial potato regional trials,and its yield was 1640 kg/667m^2,6.06% higher than that of the control variety‘Zihua 851’.It is suitable for the winter and spring planting in Fujian Province.
