Robustness of Doubly Balanced Incomplete Block Mating Designs against Unavailability of Two Blocks

Mating designs are the study of progenies developed through various methods like Diallel Cross plans which are subjected to Incomplete Block Designs. The concept of robustness in designs has been studied and available in the literature. The effects of missing blocks on Complete Diallel Cross designs are examined in this study. A-efficiencies based on non -zero eigenvalues suggest that these designs are fairly robust. The investigation shows that Doubly Balanced Incomplete Block Mating Designs are fairly robust in terms of efficiency. In this paper, the robustness of Doubly Balanced Incomplete Block Design when two blocks are lost has been discussed.
