晋北高寒地区马铃薯品系比较试验

Comparative Trial of Potato Clones in Alpine Area of North Shanxi

为筛选出适合晋北高寒地区种植的马铃薯新品种,对山西农业大学高寒区作物研究所选育出的20个优良品种(系)进行品比试验。结果表明:有8个品系较对照增产,其中“14-2-15”产量为1694 kg/667 m^(2),较对照“晋薯16号”增产49.07%,“14-15-20”产量为1609.6 kg/667 m^(2),较对照“晋薯16号”增产41.64%,“14-8-90”产量为1349.6 kg/667 m^(2),较对照增产18.76%,差异达极显著水平,可在晋北高寒地区进一步生产试验。

In order to screen out new potato varieties suitable for planting in the alpine region of northern Shanxi,20 excellent varieties selected by Institute of High Latitude and Cold Area Crops of Shanxi Agricultural University were conducted for a comparison test.The results showed that there are 8 strains with higher yield than the control.The yield of"14-2-15"is 1694 kg/667m^(2),which is 49.07%higher than the control"Jinshu 16",and the yield of"14-15-20"is 1609.6 kg/667m^(2),which is 41.64%higher than the control"Jinshu 16",the output of"14-8-90"was 1349.6 kg/667m2,which is an increase of 18.76%compared with the control.The difference reached a very significant level.It can be further tested in the alpine region of northern Shanxi.
