摘　　要：安定区气候冷凉,适宜于马铃薯生产。引进耐旱抗病及适宜于主粮化的品种,能够加快品种更新,促进安定区马铃薯产业发展。试验引进中晚熟马铃薯新品种10个,以‘陇薯6号’为对照,进行比较试验。结果表明,‘冀张薯8号’、‘L1011-15’、‘DX9’、‘天薯12号’和‘定薯4号’5个品种(系)性状表现优良,产量分别为39 200,36 133,35 267,34 183和32 833 kg/hm2,较对照分别增产43.24%、32.03%、28.87%、24.91%和19.97%;商品薯率分别为76.3%、72.8%、74.5%、70.5%和68.5%;干物质含量分别为22.6%、24.6%、26.5%、23.3%和26.3%;晚疫病发病率分别为12.39%、11.54%、12.65%、15.38%和16.92%。因此,建议这些品种(系)在安定区扩大示范推广。Anding District has cool climate which is suitable for potato production. Introduction of drought tolerant and disease resistant varieties suitable for staple food production could accelerate variety update, and promote potato industry development in Anding District. In this research, 10 new medium and late maturing potato varieties（lines） were introduced and compared using variety ＇Longshu 6＇ as a control. ＇Jizhangshu 8＇, ＇L1011-15＇, ＇DX9＇, ＇Tianshu 12＇ and ＇Dingshu 4＇ were found performing well. The yield of these varieties（lines） was 39 200, 36 133, 35 267, 34 183 and 32 833 kg/ha, and yield was increased by 43.24%, 32.03%, 28.87%, 24.91% and 19.97%, respectively, compared with the control. The marketable tuber percentage was 76.3%, 72.8%, 74.5%, 70.5% and 68.5%, and dry matter content was 22.6%, 24.6%, 26.5%, 23.3%and 26.3%. Late blight incidence rate was 12.39%, 11.54%, 12.65%, 15.38% and 16.92%. Therefore, it is suggested that these varieties（lines） be demonstrated and extended in Anding District.
