Among the crops that feed human beings, Wheat (Triticum aestivum L.) is the second most important cool season crop in India. A drastic reduction in wheat production was observed due to increasing temperature. It has been estimated that global mean temperature is rising at per decade which may cause 50% decline in wheat yields in South Asia by 2050. High temperature above than optimum has drastic effect on chlorophyll content which is also reflected by normalized difference vegetative index (NDVI). | Effect of terminal high temperature on chlorophyll content and normalized difference vegetation index in recombinant inbred lines of bread wheat
