摘　　要：【目的】评价不同甘薯品种的生态适应性,分析新疆各试验区的鉴别力,筛选出适合新疆种植的甘薯新品种,为新疆甘薯新品种的选育和推广提供依据。【方法】采用AMMI模型对2018~2019年新疆甘薯品种区域试验中的5个甘薯品种、3个试验点综合评价,分析5个甘薯品种的稳定性及丰产性,以及3个试验点的鉴别力。【结果】Z15-1和H6-1的稳定性较强,徐薯18号的稳定性较差;Z15-1属于高产稳产品种,可作为示范推广品种;H6-1、印尼紫薯属于低产稳产品种;烟薯25号和徐薯18号属于高产不稳产品种;乌苏试验点对品种的选择性最高,具有较强的代表性,伊宁试验点对品种的鉴别力低。【结论】Z15-1整体表现较好,可在新疆甘薯产区推广种植;烟薯25号和徐薯18号属于高产不稳产品种,可在局部地区示范推广。【Objective】To evaluate the ecological adaptability of different sweet potato varieties,verify the discrimination of various experimental areas in Xinjiang,and screen out new sweet potato varieties suitable for planting in Xinjiang in the hope of providing basis for the breeding and promotion of new sweet potato varieties in the region.【Method】AMMI model was used to comprehensively evaluate 5 sweet potato varieties and 3 pilots in the regional experiment of sweet potato varieties in Xinjiang Autonomous Region from 2018 to 2019 and analyze the stability and high yield of 5 sweet potato varieties and the discrimination of 3 pilots.【Result】The stability of Z15-1 and H6-1 was higher than that of Xushu 18.Z15-1 was a high and stable yield variety,which could be used as a demonstration variety.H6-1,Indonesian purple sweet potato belonged to low-yield and stable varieties;Yanshu No.25 and Xushu No.18 were high-yielding and unstable varieties.Wusu had the highest selection of varieties and had strong representativeness,while Yining had low discrimination.【Conclusion】Z15-1 shows good overall performance,and can be popularized and planted in Xinjiang sweet potato producing area.Yanshu No.25 and Xushu No.18 are high-yielding and unstable varieties,which can be demonstrated and popularized in local areas.
