Genetic Origination

Soybean performance is often influenced by the genetic origin of the variety. For instance, soybean varieties that originate in the East tend to do relatively better in cooler, wetter, clay soil types. Conversely, varieties that originate west of the Mississippi perform best in drier, well-drained, silt-loam soil types. Breeding programs that focus on the North usually develop varieties with excellent tolerance to the higher-salt and pH problems associated with those soil types. Southern varieties usually have resistance or tolerance to soybean cyst nematode, frogeye and stem canker.

For proper variety placement, it is important to consider the strengths and weaknesses of each genetic group, which are found in the following genetic origin columns. You can see how the different genetic types perform in the field at your local Answer Plot® location. Ask your CROPLAN GENETICS® seed local agronomist for more information about the Answer Plot® program in your area.
