An increase in productivity is always one of the main goals of any crop breeding program including wheat. Even though there was a series of breakthroughs the main breeding goals in most international programs remain similar since a long time ago: increasing grain yield potential, resistance to disease, grain quality, and drought tolerance. Increase in grain yield potential is the major goal of almost all wheat breeding programs. The major impacts are related to the development of new strategies to increase the genetic grain yield potential of the varieties. Wheat breeders have been very successful in improving the crop. Conventional breeding methods mainly used to improve self-pollinating crops including wheat are Pedigree, mass selection, etc, but development of hybrids, new plant types and mutation breeding are added to the breeder’s portfolio. Breeders have been taking advantage of biotechnology tools in order to accelerate wheat improvement programs as the main additional tool to conventional wheat breeding strategies; however, many programs are still struggling on how to integrate them into the breeding programs especially in developing countries. Generally to improve wheat production and productivity for the changing climate and the increasing world population as well as the increasing demands, it is advisable to use several genetic improvement strategies rather than a single method.
