Abstract Triticale is an alloploid species derived from the intergeneric hybridization between wheat and rye. There are three forms of triticale have been established; tetraploid, hexaploid and octaploid triticales. As a cereal crop, triticale has a certain desirable characteristics as compared to wheat such as: better protein quality (with high lycine content), less requirement of nitrogen fertilization, more tolerant to salinity and drought (like the rye parent in these respects). In Egypt, the production of wheat is not enough for human consumption and it comes from a limited cultivated land because of the competation between wheat and the other winter crops. It is become necessary to search for other human nutritive cereal crop has the ability to grow under unfavourable environmental conditions. The need to have additional land for farming in order to provide food for the ever increasing population in Egypt, has stimulated the interest of economists, agriculturists and successive governments planning agencies to develop the new reclamed lands especially in the northern coast region of A R. E. The role of the plant breeder in this problem is to establish and improve new varieties or strains of plant species which can grow normally in such areas. Since most of these lands are characterized by poor soil, high salinity level and low rainfall, the new varieties or strains must be tolerant to salinity, drought and poor soil conditions in order to grow normally and produce economic yields in these areas. Therefore, triticale strains seemed to be the most suitable crop for planting these areas to overcome the shortage in cereal crops production |
