“…Mutation breeding provides an opportunity without extensive upgrading crossing and selection ( Shu et al, 2012 ; Rani et al, 2016 ). Induced mutagenesis serves as one of the most productive strategies for creating evolutionary divergence as well as identifying critical regulatory genes for commercially significant features for crop improvement ( Mehta and Basha, 2018 ; Chaudhary et al, 2019a ). Forward genetics as well as reverse genetics both played crucial roles in achieving significant improvement for various economic traits ( Aklilu, 2021 ).…”

Crop improvement programmes began with traditional breeding practices since the inception of agriculture. Farmers and plant breeders continue to use these strategies for crop improvement due to their broad application in modifying crop genetic compositions. Nonetheless, conventional breeding has significant downsides in regard to effort and time. Crop productivity seems to be hitting a plateau as a consequence of environmental issues and the scarcity of agricultural land. Therefore, continuous pursuit of advancement in crop improvement is essential. Recent technical innovations have resulted in a revolutionary shift in the pattern of breeding methods, leaning further towards molecular approaches. Among the promising approaches, marker-assisted selection, QTL mapping, omics-assisted breeding, genome-wide association studies and genome editing have lately gained prominence. Several governments have progressively relaxed their restrictions relating to genome editing. The present review highlights the evolutionary and revolutionary approaches that have been utilized for crop improvement in a bid to produce climate-resilient crops observing the consequence of climate change. Additionally, it will contribute to the comprehension of plant breeding succession so far. Investing in advanced sequencing technologies and bioinformatics will deepen our understanding of genetic variations and their functional implications, contributing to breakthroughs in crop improvement and biodiversity conservation.
