摘　　要：为筛选出适宜于河西地区种植的高淀粉加工型马铃薯品种,满足马铃薯加工企业及种植户需求,笔者对引进的11个马铃薯品种开展田间比较试验,生长期调查各参试品种物候期、农艺性状、产量及品质。结果表明:‘陇薯9’号和‘青薯10号’2个品种的综合性状表现较好,‘陇薯9号’平均单株结薯数5.7个,单株产量1308.5 g,商品薯率93.9%;‘青薯10号’平均单株结薯数5.4个,单株产量1278.7 g,商品薯率92.5%。在园艺村和花寨村2个试验区,‘陇薯9号’块茎产量分别达到66919.2 kg/hm2和70555.6 kg/hm2,淀粉含量分别为18.89%和19.17%;‘青薯10号’分别达到62626.3 kg/hm2和62676.8 kg/hm2,淀粉含量分别为19.12%和18.80%。试验初步筛选出‘陇薯9号’和‘青薯10号’可作为河西沿山冷凉灌区淀粉加工型马铃薯品种推广种植。In order to select suitable varieties of high-starch-processing potato which could be planted in Hexi Region and meet the requirement of processing enterprises and farmers, comparative field tests were carriedout on 11 potato varieties, and their phenophase, agronomic characters, yield and quality were investigated ingrowth stage. The results showed that two varieties‘Longshu9＇and‘Qingshu10＇had better comprehensivecharacters, the number of tuber per plant of‘Longshu9＇was 5.7, the yield of per plant was 1308.5 g, thecommodity potato rate was 93.9%; the number of tuber per plant of‘Qingshu10＇was 5.4, the yield of per plantwas 1278.7 g, the commodity potato rate was 92.5%. In the two test sites including Horticultural village andHua- zhai village, the yield of‘Longshu9＇reached 66919.2 kg/hm^2 and 70555.6 kg/hm^2, and its starchcontents were 18.89% and 19.17%; the yield of‘Qingshu10＇reached 62626.3 kg/hm^2 and 62676.8 kg/hm^2,and its starch contents were 19.12% and 18.80%. The primary screening indicated that‘Longshu 9＇and‘Qingshu10＇were appropriated for being the starch processing potato varieties and could be promoted in thecold-cool irrigated area of Hexi along the Qilian Mountain.
