( Triticale)
× Triticale Tscherm.-Seys. ex Müntzing The word 'triticale' is a fusion of the latin words triticum (or wheat) and secale (rye). When crossing wheat and rye, wheat is used as the female parent and rye as the male parent (pollen donor). The resulting hybrid is sterile and thus has to be treated with the alkaloid chemical colchicine to make it fertile and thus able to reproduce itself. The primary producers of triticale are Germany, France, Poland, Australia, China and Belarus. In 2005, according to the Food and Agriculture Organization (FAO), 13.5 million tons were harvested in 28 countries across the world. The triticale hybrids are all amphidiploid, which means the plant is diploid for two genomes derived from different species, in other words triticale is an allotetraploid. In earlier years most work was done on octoploid triticale. Different ploidy levels have been created and evaluated over time. The tetraploids showed little promise, but hexaploid triticale was successful enough to find commercial application. (Oetler 2005)
