短平快解决因加工专用型和优质鲜食马铃薯品种匮乏难以满足市场需求的困境，进一步优化甘肃省马铃薯品种结构和布局，以推动甘肃省马铃薯产业高质量发展。对引进22个马铃薯新品种(系)在甘肃省3个不同生态区域(陇中南早熟区、河西灌区、陇中旱作区)进行了引种筛选试验，以期筛选出适宜甘肃省不同生态区域的专用马铃薯品种。结果表明，沃土5号、久恩1号、云薯304、鲁薯8号、丽薯6号、宁薯19号、同薯31号等7个马铃薯品种丰产性好，较对照品种陇薯6号分别显著增产40.5%、29.0%、20.0%、87.5%、77.0%、63.2%、45.0%；且这7个品种薯型美观、品质优良、商品薯率高，适合在甘肃省不同生态区域大面积示范推广，其中沃土5号、久恩1号可作为早中熟鲜食品种在陇中南早熟区示范推广；云薯304可作为薯条薯片加工型品种在河西灌区进行示范推广；鲁薯8号、丽薯6号可作为晚熟鲜食菜用型品种，宁薯19号、同薯31号可作为全粉主食化加工型品种在陇中旱作区进行示范推广。

To rapidly address the challenge that the shortage of processing-specialized and high-quality fresh potato variety fails to meet market demand, and to further optimize the potato variety structure and regional layout in Gansu Province for promoting high-quality development of the potato industry, 22 newly introduced potato varieties(lines) were evaluated across 3 ecological region in Gansu Province(early-maturing region in south-central Gansu, irrigated region in Hexi, and dryland region in central Gansu). The objective was to identify specialized potato variety suitable for different ecological region. The results showed that 7 potato variety, Wotu 5, Jiuen 1, Yunshu 304, Lushu 8, Lishu 6, Ningshu 19, and Tongshu 31, exhibited high yield potential, with significant yield increases of 40.5%, 29.0%, 20.0%, 87.5%, 77.0%, 63.2%, and 45.0% respectively over the control variety Longshu 6. These variety also presented attractive tuber shape, excellent quality, and high commodity rate, making them suitable for large-scale demonstration in different ecological region of Gansu Province. Among them, Wotu 5 and Jiuen 1 are recommended as early to mid-maturing fresh-consumption variety for demonstration in the early-maturing region of south-central Gansu; Yunshu 304 is suitable as a french-fry and chip-processing type in the irrigated region of Hexi; Lushu 8 and Lishu 6 can serve as late-maturing fresh vegetable-use type; Ningshu 19 and Tongshu 31 can be promoted as whole-powder staple-food-processing type in the dryland region of central Gansu.
