A method for estimating combining ability components of variance in incomplete block designs

American Potato Journal Aims and scope Submit manuscript

Summary

A method is described for estimating components of variance for specific and general combining ability from breeding experiments arranged in incomplete block designs. Utilizing published results estimates of these components of variances were computed for a potato breeding experiment arranged in a rectangular lattice design with the parameters v=200 entries, k=10 entries per incomplete block, r=6 complete blocks, and b/r=20 incomplete blocks within each complete block. The experiment was grown at three different locations thus yielding three estimates of the components of variance for combining ability. These results were used in the computations of expected genetic progress in the preceding paper of this Journal.
