湖南省马铃薯引种试验初报

Preliminary Report of Potato Introduction Experiment in Hunan Province

为筛选适宜湖南省种植的马铃薯新品种,2009年引进7个马铃薯新品种进行田间比较试验。结果表明:克200373-218产量最高,达21 900 kg/hm2,比对照东农303增产44.6%,达到极显著水平;克新17号和克新19号产量分别比东农303增产5.0%、3.0%。根据综合表现,克200373-218、克新17号和克新19号抗性强、综合性状表现好,均适宜在湖南省种植;克新18号、克200373-205、红皮、马尔科均较对照减产,有待进一步试验。
