摘　　要：江苏徐淮地区马铃薯品种种植结构单一,品种退化严重,导致病害加剧、产量及品质下降,严重制约了当地马铃薯产业发展,引进并筛选适宜当地栽种的高产、优质、抗病马铃薯新品种迫在眉睫。对新选育的4个马铃薯品种(系)进行了连续2年的比较试验,以‘中薯3号’为对照,对参试品种(系)生育期、植株性状、丰产性和抗病性等进行调查分析。结果表明,‘中薯215’高产且稳产,生育期短,商品薯性高,晚疫病、早疫病抗性较强,适宜江苏徐淮地区推广种植;‘中薯148’产量较高,生育期较短,商品薯性较高,晚疫病抗性强,适宜江苏徐淮地区种植,但稳产性还需进一步验证。In Xuhuai region,Jiangsu Province,the planting structure of potato varieties is single,and the degradation of seed potato is serious,which leads to the aggravation of disease,the decline of yield and quality,and seriously restricts the development of local potato industry.Therefore,it is urgent to introduce and select new potato varieties with high yield,high quality and disease resistance suitable for local cultivation mode.Four potato varieties(lines)were evaluated using variety'Zhongshu 3'as a control in two successive years to analyze the growth duration,plant traits,yield and disease resistance of the tested varieties(lines).'Zhongshu 215'showed stable and high yield,short growth duration,high marketable tuber percentage,resistance to late blight and early blight,which is suitable for spring planting in Xuhuai region,Jiangsu Province.'Zhongshu 148'showed relative high yield,relative short growth duration,relative high marketable tuber percentage,resistance to late blight,which is also suitable for spring planting in Xuhuai region,Jiangsu Province,but the yield stability needs to be further evaluated.
