坝上地区马铃薯品种比较试验

本试验设在内蒙古中部区商都县,采用微型薯种植,对克新1号、大西洋、夏波蒂、费乌瑞它、中联红5个马铃薯品种进行喷灌圈种植比较。结果表明:5个马铃薯品种生育期均在当地无霜期之内,能够正常收获;中联红品种抗病性较强,除轻度沾染环腐病、早疫病以外,无沾染任何病菌,其次是克新1号,而其他3个马铃薯品种易感病;中联红株高和匍匐茎数最高,分枝数却最低,费乌瑞它分枝数最高,匍匐茎数相对较低;中联红为红皮黄肉,花冠为白色;中联红和夏波蒂产量较高,与其他3个品种间达到极显著差异水平,中联红分别比大西洋、克新1号增产19.05%、38.89%;中联红品种淀粉含量最高,为19.5%,是费乌瑞它的1.58倍;克新1号还原糖含量最高,而大西洋最低;中联红和夏波蒂块茎具有较高的干物质含量。因此,在5个马铃薯品种中中联红、夏波蒂表现更优。

Comparative Test of Potato Varieties in the Highlands

Minitubers of five potato varieties,Kexin 1,Atlantic,Shepody,Favorita and Zhonglianhong,were planted in irrigation circles in Shangdu of Inner Mongolia.The growth duration of five potato varieties were within the local frost-free period.Zhonglianhong had strong disease resistance and was only slightly infected with ring rot and early blight disease,but not contaminated by other pathogens.Then,Kexin 1 followed,and other three varieties were more susceptible to diseases.The plant height and stolon numbers of ...
