[目的]选择出适宜榆林市生长的马铃薯新品种。[方法]以冀张薯8号为对照,对引进的7个马铃薯新品种开展比较试验。[结果]陇薯13号、中薯20号、冀张薯12号与对照相比增产幅度均在10%以上,这3个品种均是块茎大、整齐度均匀,陇薯13号、冀张薯12商品薯率较高;脱毒175产量为38 376.90 kg/hm^2,增产幅度为4.83%,块茎中等,整齐度均匀,商品薯率比对照偏低。[结论]陇薯13号、中薯20号、冀张薯12号商品性状好、产量高,适宜在榆林大面积推广;脱毒175产量比对照略高,但商品性状略差,较适宜在榆林推广。

[Objective] To select proper new potato cultivars grown in Yulin City. [Method] With Jizhangshu 8 as the control,the introduced seven new potato cultivars were compared.[Result] Compared with CK,Longshu 13,Zhongshu 20 and Jizhangshu 12 had more than 10% increasing range of yield,which had the characteristics of great tuber and even uniformity. Longshu 13 and Jizhangshu 12 had relatively high marketable rate. Yield of Tuodu 175 was 38 376. 90 kg / hm^2. The increasing range of yield was 4. 83%,which had the characteristics of middle tuber and even uniformity. The marketable rate was relatively lower than that of control.[Conclusion]Longshu 13,Zhongshu 20 and Jizhangshu 12 have the characteristics of good commercial characters and high yield,which are suitable for large-scale extension. Tuodu 175 has higher yield than the control,but the commercial characters are poor,which is relatively suitable for extension in Yulin City.
