Plant populations are being exposed to unique combinations of temperatures, drought stress, [CO2], and other abiotic and biotic variables as a result of current climate change. As a result, climate change is expected to have a considerable influence on agriculture and food security, albeit the impact will vary by region and crop. When combined with the growing global population, agriculture must adapt quickly to ensure future food security for this growing population. Various adaptation strategies have been used, including altering food consumption and waste, changing land and cropping practices, producing improved crop varieties, and changing land and cropping practices. Moreover, recent advancements in genetics and agronomy may be able to help mitigate some of the negative effects of climate change on food production. Long-term genetic gain through conventional breeding has gradually enhanced modern crop yields by accumulating favorable, small-effect variations that also offer yield stability through stress adaptability. Furthermore, extensive research is being conducted to address this issue, with the goal of identifying exotic genetic diversity that exhibits pronounced stress tolerance or avoidance, elucidating and introgressing the responsible genetic factors, or discovering underlying genes as a foundation for targeted genetic modification.
