摘　　要：培育和推广高淀粉玉米品种可增加玉米产业链各环节的经济效益和竞争力,对玉米生产提质增效具有重要意义。高产、高淀粉玉米品种冀玉757是以自选系冀57为母本、自选系冀2894为父本杂交选育而成,具有高产、高淀粉、粮饲通用等特点。2017~2018年参加黄淮海夏玉米组区域试验,2 a平均产量为9 570 kg/hm^(2),较对照郑单958增产4.24%;2019年参加黄淮海夏玉米组生产试验,平均产量为10 210 kg/hm^(2),较对照郑单958增产3.45%。冀玉757子粒容重732 g/L,粗蛋白含量9.00%,粗脂肪含量3.52%,粗淀粉含量76.28%,赖氨酸含量0.32%;中抗小斑病,感茎腐病、穗腐病和弯孢叶斑病,高感瘤黑粉病和南方锈病。2020年通过国家农作物品种审定委员会审定(编号:国审玉20200295)。该品种适宜在黄淮海夏玉米区的河南、山东,河北保定和沧州南部及以南地区,陕西关中灌区,山西运城、临汾、晋城部分平川地区,江苏和安徽两省淮河以北地区,以及湖北襄阳种植。栽培技术要点为:适时播种,合理密植;科学施肥,化学防控;预防病害,防治结合;粮饲通用,适时收获。The cultivation and popularization of high starch maize varieties can increase the economic benefits and competitiveness of all links of maize industry chain,and is of great significance to improve the quality and efficiency of maize production.Jiyu 757,a maize variety with high yield and high starch content,was bred by crossing Ji 57 as female parent and Ji 2894 as male parent.It has the characteristics of high yield,high starch content and general use in grain and feed.From 2017 to 2018,it participated in the regional tests of HuangHuai-Hai summer maize group,and the average yield in two years was 9570 kg/hm^(2),which increased by4.24%compared with the control Zhengdan 958.In 2019,it participated in the production test of Huang-HuaiHai summer maize group,with an average yield of 10210 kg/hm^(2),increasing by 3.45%compared with the control Zhengdan 958.The grain bulk density was 732 g/L,the crude protein content was 9.00%,the crude fat content was 3.52%,the crude starch content was 76.28%and the lysine content was 0.32%.It was moderately resistant to small spot,susceptible to stem rot,ear rot and Curvularia lunata,and highly susceptible to tumor smut and southern rust.In 2020,it was approved by the National Crop Variety Approval Committee(No.:Guoshenyu 20200295).Jiyu 757 is suitable for planting in Henan,Shandong,Baoding and the south of Cangzhou of Hebei,Guanzhong irrigation area of Shaanxi,some flat land areas of Yuncheng,Linfen and Jincheng of Shanxi,the north of Huaihe River in Jiangsu and Anhui,and Xiangyang of Hubei.Timely sowing,reasonable close planting,scientific fertilization,disease prevention and control and harvesting in time,should be pay attention to.
