The growing world population and the problems caused by climate change require the creation of crop types that are more resilient to many stresses. Several challenges that crop plants face, such as heat, salinity, drought, and mineral toxicity, may strengthen due to the current dynamic climate circumstances, ultimately affecting agricultural output. Due to resource limits and lengthy generation timeframes, traditional breeding methods sometimes encounter difficulties. A potential remedy is speed breeding, an innovative method that quickens the Plant Breeding cycle. Speed breeding allows numerous generations of crops to be produced in a shorter amount of time by adjusting environmental factors including temperature, light intensity, and photoperiod. Furthermore, speed breeding in union with high-throughput phenotyping and marker-assisted selection (MAS) techniques can enable rapid and numerous trait selections. The concepts and uses of speed breeding are examined in this chapter, with an emphasis on how it might hasten the creation of crop varieties that are more resilient to multistressors. This chapter covers the new idea of speed breeding, including its applications, methodologies, and limitations. We also talk about the difficulties and potential of this novel approach to meeting the urgent needs of contemporary agriculture.
