摘　　要：西藏马铃薯存在种性退化、品种单一等问题。为筛选出适合拉萨栽培的高产优质马铃薯新品种,开展了马铃薯新品种引进与筛选试验。试验以高产优质品种‘青薯9号’为对照,与引进的10个马铃薯新品种在拉萨市进行了一点两年品种比较试验。结果表明,‘青薯168’平均产量3 360 kg/667m^2,变异度9.317 8,商品薯率60%,属于高产稳产品种;‘丽薯10号’淀粉含量20.31 g/100g,还原糖含量仅0.22 g/100g,属于加工型品种;‘中薯19号’和‘陇薯10号’平均产量分别达3 703和3 287 kg/667m^2,变异度为4.664 5和5.140 3,且品质表现较好,属于高产稳产优质马铃薯品种,适宜在拉萨市推广种植。Few variety available and potato deterioration are problems associated with potato production in Tibet.In order to select new potato varieties with high yield and high quality suitable for Lhasa cultivation,the new potato varieties were introduced and screened.In this experiment,'Qingshu 9',a high yield and high quality variety,was compared with 10 new potato varieties introduced in Lhasa over two years.The average yield of'Qingshu 168'was 3360 kg/667m2,variability was 9.3178,and marketable tuber rate was 60%.It is a high and stable yield variety.The starch content of'Lishu 10'was 20.31 g/100g,and reducing sugar content was 0.22 g/100g,which is suitable for processing.The average yield of'Zhongshu 19'and'Longshu 10'reached 3703 and 3287 kg/667m2,respectively,with a variability of 4.6645 and 5.1403,and the quality performance was good.They are high yield and stable yield potato varieties,which are suitable for planting in Lhasa.
