What is the maize variety Dedan 5?

Dedan No.5 is a mid-mature summer sowing maize hybrid bred by Beijing Denong Seed Industry Co., Ltd.

Because this variety has many advantages such as wide adaptability, strong lodging resistance, heat resistance, stable and high yield. At present, almost all provinces in Huanghuaihai summer maize planting area have approved the introduction and filing.

The whole growth period from emergence to maturity is only 100 days, which creates conditions for middle and early maturing maize varieties and grain enrichment in the later stage.

Characteristics of maize variety Dedan 5;
