不同玉米品种的植株特性与产量结构及其增产潜力分析

Analysis on plant properties,yield components and yield potential of different maize varieties

本实验通过对郑单958、浚单20、浚单29、伟科702和中单909五个玉米品种植株特性及产量的比较,从而对其增产潜力进行分析,结果表明伟科702亩产最高为756.7kg,千粒重最高为341.00g,植株特性优良,绿叶有效功能期,抗倒能力等综合性能好,增产潜力大,是五个推广品种中最佳的品种,将有望成为黄淮生态区未来的主推品种。

This experiment compared the plant characteristics and yield of five corn varieties such as Zhengdan 958, Jundan20,Jundan 29,Weike 702 and Zhongdan 909,and analyzed their yield potential. The results showed that Wei ke702 is up to 756. 7 kg per mu and grains highest 341. 00 g,its comprehensive performance of plant characteristics,effective function period,and leaves fall resistance is good,and the production potential is high. It is the best variety of the five varieties,and is expected to be the main variety of Huanghuai zone in the future.
