Cultivation of triticale (X Triticosecale Wittmack; Triticum turgidosecale [Kiss] MK) has expanded rapidly in many regions of the world because of its improved disease resistance, yield potential, and improved grain quality. It is cultivated extensively on acidic and sandy soils of the temperate climates (i.e., Russia, Poland, France) in traditional rye areas. It is also cultivated and will further develop in the humid and semiarid subtropical environments. In the humid subtropics with acid soils, triticale's potential relies on its broad disease resistance; high yield potential; tolerance to toxicities of aluminum, manganese, and/or iron; and its efficiency in phosphorus uptake. In semiarid regions with drought or salinity stresses, adaptation is related to tolerance to boron toxicity and efficiency in utilizing water, copper, manganese, and zinc. Combining yield potential and grain quality with the characteristic hardiness of rye increases the potential of triticale for many warmer nontraditional, small grain growing areas. In southern Brazil, triticale has shown its best adaptation on the acid soils located at altitudes higher than 500 meters above sea level. At lower altitudes or in dryland cultivation in central Brazil, where mean temperatures during tillering exceed 14 degree centrigrade, triticale does not perform well and most institutions have discontinued their investigation
