Abstract
The pursuit of crop breeding for achieving global food security has been hindered by the lengthy breeding cycles required to develop suitable cultivars. Breeding efforts have long aimed to reduce crop duration with each successive generation. Speed breeding (SB) has developed as an innovative technology, offering the potential to hasten crop improvement through rapid generation advancement (RGA) and shorten the breeding cycle. SB's customized growth chambers play a crucial role in expediting plant phenotyping, crossing, mutant studies and transformation research. Although numerous crop-specific protocols for SB have been successfully developed for rice, wheat, barley and others; the SB protocol for maize remains to be established. Given the diverse applications and economic significance of maize, its production must be increased to meet future demand, making SB a promising approach for achieving this goal. This article examines the current status of SB and explores its potential for successful implementation in the future.
