A popular crop, chickpea offer healthy nourishment to the world rising population. Among pulses, chickpea (Cicer arietinum L.) is first grain legume crop to be domesticated by human commonly known as “Bengal gram or gram”. The chickpea changes how it grows in response to climate change. When the harvest season is about to expire, the crop frequently encounters moisture stress (terminal drought). If sowing is delayed, the crop can suffer heat stress during the reproductive period. A significant factor in yield loss in chickpea during the reproductive stage is high temperature. High temperature is one of the most significant abiotic constraints to chickpea growth and yield under a wide range of conditions. Climate change is now widely recognized as an inescapable occurrence and one of the most difficult concerns that mankind will face in the future. According to climate research and present production patterns, existing chickpea growing regions are under threat from rising temperatures. High temperatures have a detrimental effect on photosynthesis, respiration, membrane stability, fertilization, fruit maturity, seed quality, nutrient absorption, protoplasmic movement, material transport, hormone and primary and secondary metabolite levels. Heat tolerance is a complex trait. An effective and simple screening method with well-defined traits for selecting heat-tolerant genotypes in chickpea under field conditions is necessary for practical and economically viable breeding techniques for heat tolerance.
