Wheat, a crucial staple crop worldwide, faces a significant threat to its yield due to high-temperature stress caused by climate change. This research aims to optimize wheat yield under such conditions by investigating physiological responses and practical applications. A comprehensive literature review highlights the impact of heat stress on wheat physiology, previous mitigation strategies, and recent technological and agronomic advancements. The methodology involves selecting diverse wheat varieties, implementing controlled temperature stress conditions, and measuring key physiological and yield parameters. Results indicate that certain wheat varieties exhibit higher photosynthetic efficiency, better chlorophyll retention, improved water use efficiency, and effective leaf temperature regulation under heat stress. These physiological traits correlate with sustained yield performance, suggesting their potential for breeding heat-tolerant varieties. The study's practical applications, including adopting precision agriculture technologies, optimising agronomic practices, and educating farmers on selecting heat-tolerant varieties and managing irrigation, underscore the relevance and applicability of the research. The discussion emphasises the importance of these findings for breeding programs and proposes future research directions, such as exploring the genetic basis of heat tolerance, conducting long-term field studies, and examining the socio-economic impact of heat stress mitigation strategies. This study provides actionable insights to enhance wheat resilience to high temperatures, contributing to global food security.
