Wheat is grown in tropical and subtropical regions of the world that experience different biotic stresses. India’s wheat production is affected by heat stress on about 13.5 million ha Uttar Pradesh (UP) produce over 30% of India’s wheat production and about 14% of its rice production. Several agronomic traits are affected by heat stress conditions. Physiological and biochemical traits are controlled by multiple genes that affect heat tolerance. The CTD is dependent on many factors, including air temperature, humidity, soil conditions, and incident radiation. Using RWC, plants can be evaluated for their water status relative to their fully turgid state. In these conditions, however, plants often adapt osmotically, which maintains turgor pressure and makes the definition of 'full turgidity' difficult to determine. In wheat, chlorophyll content is related to heat tolerance and stay-green traits. The chlorophyll estimation will determine the relative amount of chlorophyll in the plant and absorbance will be measured at 663nm and 645nm, as well as other traits. GFD in bread wheat refers to the period of time between an thesis and physiological maturity. HSPs are a family of proteins that play a crucial role in protecting plants from heat stress by preventing the aggregation and denaturation of other proteins in the plant cell.
