半干旱地区马铃薯品种比较试验

摘要

In order to select the new potato varieties which can be planted in semiarid area of Wushan County, nine introduced potato varieties were compared for biological character, adaptability, disease resistance, yield and marketability. The results indicated that the adaptability, disease resistance and yield of Qingshu 9, Tianshu 10 and Tianshu 11 were better than Longshu 3, which is planted for many years as a local main cultivar. These three varieties are suitable for planting in large-scale in semi-arid area of Wushan County. Jinshu 16, Longshu 8 and Longshu 3 could be grown in some scale. Zihuabai, an early mature variety with poor drought resistance, could be planted in bank side with film mulching cultivation. 02175-200, a late mature clone with low yield and poor drought resistance, is not suitable for planting in semiarid area.%通过对引进的9个马铃薯品种进行生物学特性、适应性、抗病性、丰产性、商品性等综合农艺性状的比较试验,选择适宜武山县半干旱地区种植的马铃薯新品种。试验结果表明,青薯9号、天薯10号、11号较当地多年种植的主栽品种陇薯3号表现出较好的适应性、抗旱性和丰产性,可考虑作为武山县半干旱地区大面积示范推广种植的马铃薯品种;晋薯16号、陇薯8号、3号可适当推广种植;紫花白为中早熟品种,抗旱性差,可在川区进行地膜栽培试验;02175-200抗旱性较差,产量低,不适宜半干旱地区种植。
