a plant hybrid obtained by crossbreeding wheat (Triticum)—the maternal plant—with rye (Secale)—the paternal plant. The plants are amphidiploids and include two types: 56-chromosome and 42-chromosome. The large grain of winter triticales is winter-hardy and richer in protein than wheat grain. Winter triticales are important in the selective breeding of winter wheat in Siberia. The crossbreeding of heterochromosomal amphidiploids is promising for obtaining new highly productive forms.
