Abstract
This article presents a method for estimating and comparing experimental corn hybrids, which are candidates for release, based on their probabilities of outperforming a check. The method is useful because it (1) is easy to understand and may be conducted using SAS PROC CATMOD, (2) makes use of all available information from unbalanced data that are likely to arise from hybrid strip-test trials, (3) makes no assumptions about the underlying distribution of the trait of interest, and (4) may be used to compare test hybrids and evaluate the effects of environmental variables on the test hybrids' probabilities of outperforming a check.
