共和盆地不同马铃薯品种引进比较试验

Comparison Experiment of Introduction of Different Potato Varieties in Gonghe Basin

为筛选出适宜青海高寒地区种植的优质高产抗逆性强的马铃薯品种,以陇薯6号(CK)为对照,比较了7个品种的物候期、植株形态、田间性状、块茎性状、产量等。结果表明:闽薯4号、陇薯18号可在青海高寒地区推广种植。庄12-16-21、D1003-2、天13-12-12品质上有一定发展潜力,有必要进一步续试。天13-4-461和D0904-25产量低,可考虑将其淘汰。

In order to select high-quality and high-yield potato varieties suitable for cultivation in the alpine region of Qinghai,the phenology,plant morphology,field traits,tuber traits,yield of 7 potato varieties were compared with Longshu 6(CK)as a control.The results showed that:Minshu 4 and Longshu 18 could be planted in Qinghai alpine region.Zhuang 12-16-21,D1003-2 and Hetian 13-12-12 have certain potential for development in quality,and is necessary to do the further test.The yields of Tian 13-4-461 and D0904-25 are very low and can be considered for elimination.
