Breeding for Heat Stress Tolerance in Wheat: A Review

Abstract

Heat stress poses a significant threat to global wheat production, necessitating comprehensive strategies to enhance heat stress tolerance in wheat varieties. This study provides a summary of key findings, the importance of continued research and breeding efforts, and implications for wheat production and food security. Field trials and physiological studies have revealed substantial genotypic variation in heat stress tolerance among wheat germplasm, underscoring the need for ongoing research to identify and leverage key traits associated with heat tolerance. Continued investment in breeding programs focused on heat stress tolerance is crucial for developing resilient wheat varieties capable of sustaining productivity under changing climatic conditions. These efforts not only enhance the resilience of wheat production systems but also contribute to global food security by mitigating the impact of climate change on crop productivity and livelihoods. By prioritizing heat stress tolerance in wheat breeding programs and embracing advancements in molecular genetics and phenotyping technologies, we can pave the way for a more secure and sustainable future for wheat production worldwide.
