Abiotic stressors comprising salinity, drought, high temperatures, flooding, low nutrient availability, and heavy metal toxicity are reducing the productivity of agriculture throughout the globe. Global climate change intensifies these stresses and interferes with vital plant functions such as photosynthesis, respiration, and nutrient uptake, which lowers crop yields and increases food insecurity. Conventional breeding approaches have contributed to developing stress-resilient crop plants by selecting desirable traits within existing genetic variations or through controlled crossing. Traditional techniques like pure line and mass selection, pedigree breeding, and backcross breeding have successfully introduced traits such as drought and salinity tolerance in various crops. Nevertheless, genetic variation highly dependent on environmental conditions makes these methods time-consuming and restricted. Advanced molecular breeding techniques, including marker-assisted selection (MAS), genomics, genome editing, and genetic engineering techniques, offer more precise and efficient solutions. MAS leverages molecular markers to improve and augment the breeding process, enabling the accumulation of favorable genes for multiple abiotic stresses and making plants tolerant to multiple stresses. This amalgamation of conventional and modern breeding strategies is indispensable for developing crops that can withstand the increasing frequency and intensity of abiotic stresses. Thereby, these modern practices ensure sustainable agricultural productivity and global food security in changing climate scenarios.
