A burgeoning population and yield ceiling in major cereal crops demand a shift from conventional breeding approaches to generation advancement to a rapid generation advancement (RGA) technique. Speed breeding through RGA is already a success, and well-defined protocols are readily available for several cereal crops like wheat, barley, oats, rice, and sorghum. Extensive efforts are underway to standardize speed breeding protocols for other cereal crops. Generation advancement through modifications in light intensity, duration of exposure to different spectrums of light, temperature, and relative humidity provides an opportunity to reduce the crop growth period to take up multiple cycles per year under controlled conditions. With technological advances, several automatic, semi-automatic, aerial, and ground-based precise phenotyping platforms for field and control conditions are available. Sensor- or image-based phenomics facilities have enabled screening for biotic and abiotic stress tolerance, profiling of nutritional quality traits, phenotyping for agronomic traits, and studying root architecture effectively. UAVs and drones are capable of recording the agronomic traits of large populations in order to assist breeders in their decision-making. Speed breeding and high-throughput phenotyping platforms, in combination with advanced genomic tools like marker-assisted selection, genomic prediction, genomic selection, and genome editing, can accelerate the genetic gains in several crop species, including cereals. With a view to harnessing the enormous potential of these technologies in cereal crops, a comprehensive study of the present scenario and future prospects is presented in this chapter.
