半干旱区马铃薯品种性状比较试验

Comparative Test of Characteristics for Potato Varieties in Semi-arid Region

为筛选出适合甘肃中部半干旱区种植的高产抗逆性强的马铃薯品种,通过田间试验,对新引进的6个马铃薯品种在甘肃会宁半干旱区进行品种比较试验。结果表明,脱毒薯‘青薯168’、‘庄薯3号’和‘黑蛋’产量较当地大面积种植常规品种‘青薯168’(CK)增产32.19%以上,产量差异极显著,且综合农艺性状好,可做为甘肃中部半干旱地区大面积推广品种。

Virus-free seeds of six varieties were introduced and compared to local regular seeds of variety ＇Qingshu 168＇in order to select high yielding and high resistant potato varieties suitable for planting in Huining County, a semi-arid region of central Gansu Province. Yields of virus-free seeds of ＇Qingshu 168＇, ＇Zhuangshu 3＇ and ＇Heidan＇ were at least 32.19% higher than the local regular seeds of ＇Qingshu 168＇（CK）, and the differences were highly significant. Also, these varieties did well in comprehensive agronomic characteristics, and therefore could be extended in large scale in the semi- arid region of central Gansu Province.
