高原干旱半干旱区马铃薯新品种引进筛选试验

Introduction and Screening of New Potato Varieties in Arid and Semi-arid Areas of the Plateau

为了筛选出适宜当地种植的马铃薯品种,引进了9个马铃薯供试品种,以当地主栽品种陇薯7号为对照进行了品种比较试验。结果表明,青薯9号、陇薯15号、陇薯10号3个品种综合指标较好、干物质含量较高,分别达23.3%、23.7%、21.9%,且抗旱能力强,分别较对照增产5 717.1、4 696.2、3 675.2 kg/hm^(2),增产率分别为26.2%、21.5%、16.8%,作为中晚熟品种,可在当地大面积种植推广。希森6号和V7较对照相比分别增产1 020.9、612.5 kg/hm^(2),增产率分别为4.7%、2.8%,抗旱、抗病性能好,蛋白含量高,作为早熟品种可在当地大面积种植推广。

In order to select suitable potato varieties for local cultivation,9 potato varieties were introduced for trial,and a variety comparison experiment was conducted with the main locally grown variety Longshu 7 as the control.The results showed that the comprehensive indicators of Qingshu 9,Longshu 15,and Longshu 10 were good,with high dry matter content,reaching 23.3%,23.7%,and 21.9%,respectively.They also had strong drought resistance,increasing yield by 5717.1,4696.2,and 3675.2 kg/hm^(2) compared to the control,with yield increase rates of 26.2%,21.5%,and 16.8%,respectively.As mid to late maturing varieties,they could be widely planted and promoted in the local area.Compared with the control group,Xisen 6 and V7 increased production by 1020.9 and 612.5 kg/hm^(2),with an increase rate of 4.7%and 2.8%,respectively.They had good drought resistance and disease resistance,high protein content,and could be widely planted and promoted as early maturing varieties in the local area.
