Improved Maize varieties released and registered in Ghana is a compilation of improved maize varieties and their characteristics.
These maize varieties released possess characteristics that enable cultivation in the varying ecological and climatic zones in the country. With improved yields and short maturity periods, they help to solve the problem of hunger and low-income farmers. Additionally, they are improved to have better nutritional benefits when consumed by human or livestock.
Here is a list of improved maize varieties released in Ghana with distinct features, values, are suited for cultivation and more.
**Note**
