“…Breeding varieties tolerant to specific problematic soils pose a great challenge for plant breeders, which necessitates unraveling the mechanisms and traits/genes associated with salinity, sodicity, and acidity tolerance [37,38]. A number of mapping studies have been attempted to identify candidate genes or QTLs for salinity tolerance in different crops including rice [39][40][41][42][43], wheat [44], and chickpeas [45]. However, limited progress has been made in the development of salt-tolerant cultivars.…”

The abiotic stresses, such as drought, waterlogging, heat, cold, and salinity, cause significant crop yield losses associated with extremes of moisture and temperature and ion imbalance. The occurrence of these conditions is being aggravated by climate change, global warming, and industrial pollution. It is crucial to safeguard food security through a constant and sustainable crop production system under multiple abiotic stresses. The cultivation of climate-resilient varieties is one of the best strategies being followed across diverse agroecosystems in the world including India to mitigate the impact of abiotic stress on crop production. Indian agricultural institutional network under the umbrella of the National Agriculture Research System developed a good number of abiotic stress-tolerant varieties across the field and horticultural crops. However, only a few crops’ varieties’ introgression with SUB1 gene and salinity tolerant QTLs are being cultivated largely in the areas prone to submergence and salinity stress, respectively. In this book chapter, we have updated the status of abiotic stress tolerance crop varieties (ASTCVs) along with stress-wise trend analysis to disseminate information among farmers, students, scientists, and policymakers involved in abiotic stress management. Finally, we also discussed the strategies to reorient the breeding program to develop climate-smart varieties with multiple biotic and abiotic stress tolerance.
