The higher order mating designs like triallel and double crosses have been found to be useful in exploiting the epistatic gene action. However, it is equally important to note that enormous amount of resources are necessary to develop triallel crosses even for a small number of genetic lines p as it involves developing p(p —1)( p —2)/2 distinct three way hybrids. A simple answer to this problem is to consider a sample of triallel crosses known as partial triallel crosses (PTC) which retains the salient properties of triallel crosses at less cost. In this paper we consider the estimation of variance components (design and genetic) based on partial triallel mating designs.
