Soybean, Glycine max (L) Merr., is a major industrial and food crop cultivated worldwide. It is an important commodity recommended for solving malnutrition and is also an important ingredient in animal feed. There have been developments over the years to achieve high-yielding soybean varieties.
These are improved soybean varieties released and registered in Ghana.
