摘　　要：选择浚单系列品种浚单18、浚单98-3、浚单20、浚单26玉米杂交种,以郑单958和农大108为对照,研究这4个品种后期子粒灌浆特性。结果表明,浚单系列品种的产量明显高于对照,穗粒数和百粒重对产量的贡献基本相同,浚单20、浚单26、浚单18、浚单98-3的子粒体积和灌浆速率均大于郑单958和农大108。选择高水肥地,加强生育后期的水肥管理,可充分发挥浚单系列玉米杂交种的增产潜力。In the experiment, the Xundan series maize varieties of Xundanl8, Xundan98-3, Xundan20 and Xundan26 were selected to study the grain filling characteristic with Zhengdan958 and Nongdal08 as CK. The results showed that the yield of Xundan series varieties was positively higher than CK. The contribution of the grain number per spike and 100-grain weight to yield was similar. The grain volume and grain filling rate of Xundan20, Xundan26, Xundanl8 and Xundan98-3 was bigger than Zhengdan958 and Nongdal08. So to selected regions with enough water and fertilizer and to strengthen the manager of water and fertilizer could reach the yield potential of Xundan series maize varieties.
