Corn Production

Hybrid Selection/Genetics

Hybrid selection is one of the most important factors to understand and consider each growing season. In this topic you will find information addressing how to properly select hybrids based on criteria such as yield, profitability, and risk management. Resources are also listed which address the incorporation of genetic traits that cause plant resistance towards certain insects and herbicides.
