邯玉398是邯郸市农业科学院以自交系H39-1为母本、自交系H74为父本杂交选育的玉米新品种。2014~2015年河北省夏播高密组区域试验,该品种平均产量为11 149.5 kg/hm2,较对照郑单958增产5.1%;2016年河北省夏播高密组生产试验,该品种平均产量10 138.5 kg/hm2,较对照郑单958增产5.3%。该品种高抗矮花叶病,中抗大斑病和茎腐病,抗小斑病和穗腐病;倒伏和倒折率平均值均<3%。2017年4月通过河北省农作物品种审定委员会品种审定。适宜在河北省唐山市、廊坊市及其以南的夏播玉米区夏播种植。

A new maize hybrid Hanyu 398 was bred with inbredline H39-1 as female parent and inbredlineH74 as male parent by Handan Academy of Agricultural Sciences. In the regional test of high density group inHebei,the average yield was 11 149.5 kg/hm2and with 5.1% higher than that of control Zhengdan 958 in2014 and 2015. In the production test of high density group in Hebei,the yield was 10 138.5 kg/hm2,whichwas higher by 5.3% than that of control Zhengdan 958 in 2016. It has high resistance to scmv,moderateresistance to leaf blight and stalk rot,and resistance to southern leaf blight and ear rot. The lodgding rate andreversal rate were all lower than 3%. It was approved by Hebei Crop Variety Approval Committee in April2017. It was suitable for sowing in summer sowing areas of Tangshan and Southern Langfang.
