摘要
为筛选适应马铃薯主粮化战略需求的高产多抗优质马铃薯新品种,以定西市主栽品种‘新大坪’、‘陇薯6号’为对照,对10个引进品种进行比较试验,综合比较分析了各品种的生物学特性、丰产性、抗逆性、商品性和营养品质等性状。结果表明,‘青薯9号’、‘冀张薯8号’和‘陇薯10号’3个品种产量较高,分别为55774,46904和45982 kg/hm^2,较‘新大坪’分别增产21280,12410和11488 kg/hm^2,增产率分别为61.7%,36.0%和33.3%;较‘陇薯6号’分别增产21042,12172和11250 kg/hm^2,增产率分别为60.6%,35.0%和32.4%。这3个品种抗旱抗病性强,商品性、营养品质较好,符合马铃薯主粮化品种要求,具有良好的主粮化开发前景,可在干旱半干旱地区大面积示范种植。
Ten introduced varieties were compared with the main varieties of Dingxi City,'Xindaping'and'Longshu 6',and their biological traits,yield,stress resistance,commodity characteristics and nutritional qualities were comprehensively compared and analyzed in order to screen new potato varieties with high yield,multi-resistance and high quality to meet the strategic demand of potato as staple food.The yields of'Qingshu 9','Jizhangshu 8'and'Longshu 10'were 55774,46904 and 45982 kg/ha,respectively,which were 21280,12410 and 11488 kg/ha higher than that of'Xindaping',and the yield increased by 61.7%,36.0%and 33.3%,respectively.When they were compared with'Longshu 6',the yields were increased by 21042,12172 and 11250 kg/ha,and the yield increased by 60.6%,35.0%and 32.4%,respectively.These three varieties have strong drought and disease resistances,good commercial and nutritional qualities,and meet the requirements of potato variety for use as staple food.They have good prospects for development as staple food and could be planted in large-scale demonstration in arid and semi-arid areas.
