August 10, 2020 – What do you look forward to in the morning? A cup of tea? Coffee? What about cereal, or toast with jam? Around the world, families eat various foods for breakfast – and all those foods have a constant threat over them. The August 7th Sustainable, Secure Food blog explores how certain diseases affect common breakfast foods and how breeders are combating them.
According to bloggers Claire Poore and Mallowa Sally, “one of the biggest threats to global wheat supply is the disease wheat stem rust. This fungal disease dates to the Roman Empire. Infections can be seen by spots on the stem and leaves that have rust-colored powdery spores in them. These spots affect the plant by reducing the plant’s ability to photosynthesize. This reduces the number and size of the wheat kernels.”
While the disease is managed by the development of resistant varieties, every few decades a new strain appears that the currently grown varieties do not have resistance to. In 1999 a new fast-spreading strain of the fungus was detected in Uganda called Ug99. It devastated yields and reduced the milling quality of the grain. Rust spores can travel long distances, spreading the disease quickly throughout Africa and the Middle East. Currently, it threatens to wipe out more than 80% of existing varieties. Food security in developing countries is largely dependent on wheat.
