ABSTRACT
Discusses diallel, a popular mating design used for crop and tree breeding programs. Description of how its unique feature of a single observation with two levels of the same main effect, general combining ability (GCA), makes it difficult to analyze with standard statistical programs; Development of a new approach using the SAS PROC MIXED in this study for analyzing genetic data from diallel mating; Details of the study; How the new method can be used for predicting individual breeding values with best linear unbiased predictors (BLUP) methodology, applying SAS IML to the outputs provided by PROC MIXED to calculate breeding value for each individual in the progeny test, adjusted for the fixed effects such as test location; Suggestion that the accurate BLUP prediction, the ability to estimate individual breeding values, and the ease of use would make this new method especially attractive for analyzing tree breeding data.
