Summary
The augmented partial diallel cross is a design for estimating general and specific combining abilities in which one or more primary lines are crossed with all others, but the lines of secondary interest form a partial diallel cross. There are up to four variances of inter-line comparisons, depending on whether the lines are primary or secondary and whether they are crossed or not, and approximate expressions are given for these variances. The approximations are sufficiently accurate to determine the variance properties of any given design.
