| Abstract: | 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. |
