ABSTRACT

The estimation process of general and specific combining abilities as well as their corresponding sums of squares obtained from unbalanced diallel systems in which progenitors and/or hybrid combinations were evaluated with an unequal number of replications. As an illustration, the hypothetical data sets of a diallel involving progenitors and the corresponding F₁'s and another involving only fhe F₁'s were analysed.

Keywords: Diallel crosses.
