Cotton is an important cash crop in addition to being a fiber commodity, and it plays an essential part in the economies of numerous nations. High temperature is the most critical element affecting its yield from fertilization to harvest. The optimal temperature for root formation is 30 C -35 °C; however, root development ends around 40 °C. Increased temperature, in particular, influences different biochemical and physiological processes associated with cotton plant, resulting in low seed cotton production. Many studies in various agroecological zones used various agronomic strategies and contemporary breeding techniques to reduce heat stress and improve cotton productivity. To attain desired traits, cotton breeders should investigate all potential possibilities, such as generating superior cultivars by traditional breeding, employing molecular techniques and transgenic methods, such as using genome editing techniques. The main objective of this review is to provide the recent information on the environmental factors, such as temperature, heat and drought, influence the growth and development, morphology and physio-chemical alteration associated with cotton. Furthermore, recent advancement in cotton breeding to combat the serious threat of drought and heat stress.
棉花不仅是一种纤维商品，还是一种重要的经济作物，在许多国家的经济中发挥着重要作用。高温是影响其从施肥到收获产量的最关键因素。根系形成的最佳温度为30℃-35℃；然而，根系发育在40℃左右结束。特别是温度升高会影响与棉花植株相关的不同生化和生理过程，导致籽棉产量降低。不同农业生态区的许多研究采用了各种农艺策略和现代育种技术来减轻热应激并提高棉花生产力。为了获得理想的性状，棉花育种者应研究所有潜在的可能性，例如通过传统育种培育优良品种，采用分子技术和转基因方法，如使用基因组编辑技术。本综述的主要目的是提供有关温度、高温和干旱等环境因素影响棉花生长发育、形态以及理化变化的最新信息。此外，还介绍了棉花育种在应对干旱和热应激严重威胁方面的最新进展。
