坝上地区马铃薯品种比较试验

Comparative Test of Potato Varieties in the Highlands

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。

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 ...
