Abstract

Selecting high yielding corn hybrids is the most difficult thing that corn producers must do each year and the most important management decision that affects profitability Production costs are fixed for a given set of management practices for each grower, so any increase in yield because of selecting good yielding hybrids adds extra net income and increases profitability potential. In this discussion, I will present a process for selecting corn hybrids that increases a grower's probability of obtaining high corn yields. I will show the data that support the process which simply is to get yield information from several locations of small, replicated yield trials. One then needs to rank the hybrids based on the average over locations, and then starting from the top and go down the list select as many hybrids as the grower wants to grow. This process only considers yield; one can consider other traits such as stalk quality, genetic traits, etc.
