“…Among abiotic stressors, heat stress is one of the most detrimental constraints, limiting cotton production by disturbing its normal growth, physiological, and developmental processes. Pakistan ranks fifth among top cotton-producing countries after India, China, United States, and Brazil (Khan et al, 2020), even though the nations cotton zone average temperature ranks highest among cotton-growing areas worldwide (Saleem et al, 2021). In Pakistan, the average temperature of the cotton-growing belt remains at 37 • C/25 • C (day/night) as compared to the United States 30 • C /24 • C, China's 29 • C/18 • C, and India's 34 • C/21 • C (Saleem et al, 2021).…”

The ever-changing global environment currently includes an increasing ambient temperature that can be a devastating stress for organisms. Plants, being sessile, are adversely affected by heat stress in their physiology, development, growth, and ultimately yield. Since little is known about the response of biochemical traits to high-temperature ambiance, we evaluated eight parental lines (five lines and three testers) and their 15 F1 hybrids under normal and high-temperature stress to assess the impact of these conditions over 2 consecutive years. The research was performed under a triplicate randomized complete block design including a split-plot arrangement. Data were recorded for agronomic, biochemical, and fiber quality traits. Mean values of agronomic traits were significantly reduced under heat stress conditions, while hydrogen peroxide, peroxidase, total soluble protein, superoxide dismutase, catalase (CAT), carotenoids, and fiber strength displayed higher mean values under heat stress conditions. Under both conditions, high genetic advance and high heritability were observed for seed cotton yield (SCY), CAT, micronaire value, plant height, and chlorophyll-a and b content, indicating that an additive type of gene action controls these traits under both the conditions. For more insights into variation, Pearson correlation analysis and principal component analysis (PCA) were performed. Significant positive associations were observed among agronomic, biochemical, and fiber quality-related traits. The multivariate analyses involving hierarchical clustering and PCA classified the 23 experimental genotypes into four groups under normal and high-temperature stress conditions. Under both conditions, the F1 hybrid genotype FB-SHAHEEN × JSQ WHITE GOLD followed by Ghuari-1, CCRI-24, Eagle-2 × FB-Falcon, Ghuari-1 × JSQ White Gold, and Eagle-2 exhibited better performance in response to high-temperature stress regarding the agronomic and fiber quality-related traits. The mentioned genotypes could be utilized in future cotton breeding programs to enhance heat tolerance and improve cotton yield and productivity through resistance to environmental stressors.

“…The presence of maximum transcription factors might have improved the relative water content, photosynthesis, low leaf-air temperature and high boll retention percentage under drought stress condition ( Table 2 ). The variety MNH-886 has also been reported as heat tolerant by analysing the impact of HSPs ( Saleem et al, 2021 ) The varieties breed here are naturally tolerant to heat stress as cotton withstand highest temperature here as compared to any other cotton growing area around the world. The transcription factors/gene such as MAPK, DREB, APX improves drought tolerance by improving physiological mechanism against drought stress ( Zhang and Huang, 2020 , Hou et al, 2018 , Nawaz et al, 2020 ).…”

“…Higher stomatal conductance was associated with higher relative water content and coolness of leaf temperature in this study as well as in literature. The plant with ability of keeping leaf cooler was associated with higher boll retention percentage which is associated with drought and heat stress tolerance ( Iqbal et al, 2017 ; Saleem et al, 2021 ). The role of the presence of transcription factors/genes has been checked through the correlation analyses, where number of stress related transcription factors/genes showed a significant and positive correlation with stress related physiological traits and boll retention ( Table 3 ).…”

“…Tolerant germplasm exists in the areas where climatic conditions are naturally severe. Pakistani cotton crop tolerates highest temperature as compared to any other country’s cotton ( Saleem et al, 2021 ). The country is also dropped to a water stressed country as freshwater availability is declining.…”

“…GhMKK1 also proved to be an important regulator against environmental stresses as well as works as an antioxidant, whereas GhMKK3 regulates stomatal responses and root growth under drought stress ( Wang et al, 2016 ). HSPs (Heat Shock Protein Genes) help cotton plants to withstand heat stress ( Saleem et al, 2021 ). A variety of HSPs has been studied in plants.…”

Climate change could be an existential threat to many crops. Drought and heat stress are becoming harder for cultivated crops. Cotton in Pakistan is grown under natural high temperature and low moisture, could be used as a source of heat and drought tolerance. Therefore, the study was conducted to morphological, physiological and molecular characterization of cotton genotypes under field conditions. A total of 25 cotton genotypes were selected from the gene pool of Pakistan based on tolerance to heat and drought stress. In field trail, the stress related traits like boll retention percentage, plant height, number of nodes and inter-nodal distance were recorded. In physiological assessment, traits such as photosynthesis rate, stomatal conductance, transpiration rate, leaf temperature, relative water content and excised leaf water loss were observed. At molecular level, a set of 19 important transcription factors, controlling drought/heat stress tolerance (HSPCB, GHSP26, HSFA2, HSP101, HSP3, DREB1A, DREB2A, TPS, GhNAC2, GbMYB5, GhWRKY41, GhMKK3, GhMPK17, GhMKK1, GhMPK2, APX1, HSC70, ANNAT8, and GhPP2A1) were analyzed from all genotypes. Data analyses depicted that boll retention percentage, photosynthesis, stomatal conductance, relative water content under the stress conditions were associated with the presence of important drought & heat TF/genes which depicts high genetic potential of Pakistani cotton varieties against abiotic stress. The variety MNH-886 appeared in medium plant height, high boll retention percentage, high relative water content, photosynthesis rate, stomatal conductance, transpiration rate and with maximum number transcription factors under study. The variety may be used as source material for heat and drought tolerant cotton breeding. The results of this study may be useful for the cotton breeders to develop genotype adoptable to environmental stresses under climate change scenario.
