The fast growth of the human population has made food security a more pressing global issue. Crop improvement initiatives are not progressing at a rate that can keep up with the increasing need for food, despite the challenges posed by a fast-expanding population and a continuous changing climate. Redesigning crop plants urgently is necessary to meet this challenge and guarantee higher production, long-term nutrition, and climate resistance. Researchers all across the world are increasingly using speed breeding as a game-changing tactic. In addition to producing many crop generations in a single year, this innovative technique drastically shortens the breeding period. Speed breeding is an integrated approach that combines cutting-edge genetic engineering techniques with traditional breeding procedures to improve breeding efficiency. Breeders can maximize production results by adjusting variables including temperature, time, and light intensity. Accelerated breeding alone won’t be enough to successfully and quickly commercialize agricultural varieties; other tactics including phenotyping, genome selection, re-domestication, and gene editing are needed. By using these integrated approaches, plant breeders can potentially meet the expanding global population’s food needs in the future in addition to helping them adapt to a changing environment. Speed breeding combined with these useful methodologies not only expedites crop variety testing, production, and release but also holds promise for tackling the major concerns related to food security in the years to come.
