河南春季马铃薯引种比较试验

Comparative Experiment on Introduction of Spring Potato in Henan Province

以中薯5号为对照,采用完全随机区组设计,在河南郑州对引进的7个马铃薯品种(系)进行比较试验。结果表明:9728-04、05HE5-43、F04046较对照中薯5号增产15.88%~26.76%,商品薯率为71.3%~81.0%,适宜在河南春季种植;F00070较对照中薯5号略有减产,但抗病性较好,皮色为黄带紫色,可以作为特色马铃薯进一步试验筛选;08CA0710、08CA0623和CS74109-8较对照中薯5号分别减产7.27%、47.06%、19.92%,不适宜河南种植。

Seven introduction potato lines were compared with potato 5 in Henan Province,which adopted complete randomized block design.The results showed that compared with the contrast,the yield of 9728-04、05HE5-43、F04046 increased 15.88% -26.76%,commodity potato rate were71.3% -81.0%,which were suitable for planting in spring in Henan Province;the yield of F00070 decreased slightly,but the disease resistance was better,the color of potato skin was yellow with purple,which can be used as a characteristic potato in further screening;the yield of 08CA0710、08CA0623 and CS74109-8 decreased 7.27%、47.06%、19.92%,which were not suitable for planting in Henan Province.
