摘　　要：为研究不同产地与不同品种对马铃薯品质的影响,对7个不同马铃薯品种在甘肃省具有代表性的旱作农业县(区)(古浪县直滩乡、安定区香泉镇、渭源县会川镇、庄浪县通化乡和环县甜水镇)进行多点试验。方差分析结果显示,品种和产地因素极显著影响马铃薯块茎干物质含量、粗蛋白含量,品种×产地互作对马铃薯块茎干物质含量影响极显著,对粗蛋白含量的影响不显著;马铃薯块茎粗淀粉含量、维生素C含量受品种因素影响显著,产地因素和品种×产地互作效应对其影响不显著;产地因素显著影响马铃薯块茎中K含量、极显著影响Ca含量、Se含量,品种因素和品种×产地互作对马铃薯块茎中K含量、Ca含量、Se含量影响不显著;马铃薯块茎中Zn含量受产地因素影响极显著,品种对马铃薯块茎中Zn含量的影响显著,品种×产地互作效应对马铃薯块茎中Zn含量的影响不显著。研究结果可为提升马铃薯营养品质提供参考。The experiment involving seven varieties were conducted in five locations(Zhitan Township,Gulang County;Xiangquan Township,Anding District;Huichuan Township,Weiyuan County;Tonghua Township,Zhuanglang County;and Tianshui Township,Huanxian County)from representative dry farming areas in Gansu Province in order to investigate the effects of variety and location on the nutrient quality of potato.Variety and location had a highly significant effect on dry matter and crude protein contents of potato tubers,and the effect of variety×location interaction on the dry matter content was highly significant,but not significant on crude protein content.Variety had a significant effect on crude starch and vitamin C contents of potato tubers,but location and variety×location interaction had no significant influence.The location significantly affected K contents,and highly significantly affected Ca and Se contents in potato tubers,but varieties and variety×location interaction had no significant effect on K,Ca and Se contents in potato tubers.Location had highly significantly effect and variety had significant effect on Zn contents,but variety×location interaction had no significant effects.The results could provide references for improving the nutritional quality of potato.
