Abstract

Speed Breeding is a novel and exciting way to breeding that was inspired by the US National Aeronautics and Space Administration (NASA) that promises to develop new crop types faster, giving hope to the continent's food security. The method entails growing plants in continuous light for 20-22 hours. Plants can photosynthesize over extended periods of time, resulting in faster growth. Under normal growth conditions, two generations of wheat plants can be developed per year, but with this approach, four to six generations can be grown per year. As a result, researchers are increasingly employing this technique in plant phenotyping and the pyramiding of several traits for the production of novel crop varieties. However, significant problems and constraints prevent its widespread implementation across a wide range of crops.
