摘　　要：陇薯7号是以庄薯3号为母本、以菲多利为父本的杂交后代选育而成的马铃薯新品种。晚熟,生育期120d(天)左右,薯块休眠期长。薯块长椭圆形,黄皮黄肉,芽眼较浅,表皮光滑,商品薯率80%,干物质含量25.2%,淀粉18.75%,VC203.1mg·kg-1,粗蛋白2.68%,还原糖0.18%。对晚疫病和花叶病毒病的抗性优于渭薯1号。每667m2产量2000kg左右,高产可达3000kg,适宜甘肃省高寒阴湿、二阴地区及半干旱地区推广种植。陇薯7号是以庄薯3号为母本、以菲多利为父本的杂交后代选育而成的马铃薯新品种。晚熟,生育期120d(天)左右,薯块休眠期长。薯块长椭圆形,黄皮黄肉,芽眼较浅,表皮光滑,商品薯率80%,干物质含量25.2%,淀粉18.75%,VC203.1mg·kg-1,粗蛋白2.68%,还原糖0.18%。对晚疫病和花叶病毒病的抗性优于渭薯1号。每667m2产量2000kg左右,高产可达3000kg,适宜甘肃省高寒阴湿、二阴地区及半干旱地区推广种植。Abstract ‘Longshu No. 7 ＇ is a new potato variety developed by crossing female parent‘Zhuangshu No. 3 ＇ with male parent‘ Fritolay＇. It is a late maturing variety, and takes about 120 days from sowing to harvest. Its dormancy period is very long. The tuber is of long ellipse shape with yellow skin and flesh. Its bud eyes are shallow. Its surface is smooth. The rate of commercial tuber is 80 %. The average content of dry matter is 25.2 % ,starch is 18.75 % ,VC is 203.1 mg·kg^-1 ,crude protein is 2.68 % ,reducing sugar is O. 18 %. It has stronger resistance to late blight and mosaic virus than that of ‘ Weishu No. 1 ＇. It can yield 30 t ·hm^-2 ,and even higher as 45 t · hm^-2. It is suitable to be cultivated in the region with high altitude and low temperature, in half shaded land and semi-arid area of Gansu province.
