Abstract
Speed breeding (SB) technology is an innovative solution to shorten the breeding cycle and accelerate crop improvement. The key factors of plant growth and development, including photoperiod, light intensity and quality, temperature, relative humidity, planting density and plant nutrition are manipulated in such a way as to stimulate flowering and seed set under controlled conditions. The development of SB technology may be challenging as crops tend to vary in their response to physiological manipulations. Therefore, crop-specific optimization is highly critical to developing successful SB technology in crops. The SB technology can also be synergisticallyintegrated with cutting edge genomics and markerassisted selection technologies to enhance genetic gain in crop breeding programmes. In this review,various aspects concerning the science and techniques underpinning SB technology, the successful implementation of SB technology in different crops, the inherentchallenges faced, and the potential opportunities to integrate SB technology with cutting-edge genomics technologies towards accelerating crop improvement are discussed.
