In breeding studies, the genetic resources that contain these traits are of great importance in order to transfer the desired characteristics to the new generation. There are genes that increase soil and subsoil biomass that provide tolerance to diseases and pests, tolerance to cold and drought also in rye for wheat breeding. Wheat gene sources derived from rye and triticale used in order to transfer these traits into breeding material. As a result of the translocations which are formed in this way and which mean the reciprocal displacement of two different chromosomal fragments, grain yield increase was observed in the obtained genotypes. In addition, in studies conducted in different countries, wheat genotypes with tolerance to biotic and abiotic stress conditions have been developed by these methods. Although, Turkey is gene center for wheat and rye, it is understood that, the required importance is not given to gene transfer from rye. In the direction of the current researches, studies on transferring chromosome particles around the world have been summarized so far in order to give the necessary subject to this issue in the wheat breeding programs in our country.
