摘　　要：马铃薯是甘肃省旱作区的优势农作物,优良品种的应用是当地马铃薯产业增效的首要因素。引进18个马铃薯新品种在庄浪县旱地梯田进行品种比较试验,采用当地主栽品种‘克新2号’为早熟对照品种、‘庄薯3号’为晚熟对照品种,以筛选适宜甘肃陇东干旱半干旱区推广种植的马铃薯新品种。结果表明,‘华颂7号’‘中薯9号’和‘华颂11号’综合经济性状优良,生育期短,抗晚疫病,在参试早熟品种中产量最高,分别为33932,29544和27638 kg/hm2,分别较对照‘克新2号’增产9081,4693和2787 kg/hm2,增产率分别为36.54%,18.88%和11.21%,可作为早熟品种在庄浪县及同类生态区域推广种植;‘DS8’‘中薯19号’和‘陇薯6号’综合性状优良,生育期适中,在参试晚熟品种中产量居前三位,分别为40499,35850和35790 kg/hm2,分别较对照‘庄薯3号’增产5400,751和691 kg/hm2,增产率分别为15.39%,2.14%和1.97%,可作为晚熟品种在庄浪县及同类生态区域推广种植。Potato is a dominant crop in dry farming area of Gansu Province,and the application of adapted varieties is the primary factor to increase the efficiency of local potato industry.In this study,18 new potato varieties were introduced to dryland terraces in Zhuanglang County for variety comparison test.Local main cultivar'Kexin 2'was used as early maturing control variety and'Zhuangshu 3'as late maturing control variety to screen new potato varieties suitable for planting in arid and semi-arid areas of eastern Gansu Province.'Huasong 7','Zhongshu 9'and'Huasong 11'had good comprehensive economic characters,short growth period and resistance to late blight.Among the tested early maturing varieties,their yields were 33932,29544 and 27638 kg/ha,respectively,which were 9081,4693 and 2787 kg/ha higher than that of the control'Kexin 2',and their yield increase rates were 36.54%,18.88%and 11.21%,respectively.They could be planted as early maturing varieties in Zhuanglang County and other similar ecological areas.'DS8','Zhongshu 19'and'Longshu 6'had good comprehensive characters and moderate growth period.The yields of'DS8','Zhongshu 19'and'Longshu 6'ranked the top three among the late maturing varieties tested,which were 40499,35850 and 35790 kg/ha,respectively,increased by 5400,751 and 691 kg/ha,respectively,compared with the control'Zhuangshu 3',and the yield increase rates were 15.39%,2.14%and 1.97%,respectively.They could be planted as the late maturing varieties in Zhuanglang County and other similar ecological areas.
