“…Like most crop plants, cotton is susceptible to heat stress, especially during the developmental ( Zahid et al, 2016 ) and reproductive phases ( Salman et al, 2019 ). The most notable effects include flower shedding at the flowering phase, leading to stunted growth and reduced boll weight, and ultimately lower yields ( Xu et al, 2020 ).…”

“…Through conventional breeding, a significant level of tolerance in cotton can be achieved. Moreover, the global mean temperature is constantly increasing, urging cotton breeders to search for hidden potential genotypes from the existing germplasm via effective screening approaches based on particular morphological, biochemical, and physiological traits ( Salman et al, 2019 ). The selection of cotton genotypes tolerant to heat stress is a prerequisite for cotton breeding improvement programs.…”

“…Singh et al, 2007 reported that each 1 • C rise of temperature in the field reduces the SCY by 110 kg ha −1 . Pollen tube germination, growth, and elongation are adversely affected by a temperature increase from 28 to 30 • C. At 28 • C, optimum pollen germination occurs (Burke et al, 2004) and the germination rate decreases as the temperature rises sharply from 28 to 37 • C. Therefore, hightemperature stress reduces the germination rate, plant growth, photosynthetic rate, fruiting branches, membrane integrity, boll weight, and increases boll abscission, all of which lead to lower yield (Salman et al, 2019). Heat stress is also related to reduced boll size and the number of seeds per boll that limit fertilization efficiency (Pettigrew, 2008).…”

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.

“…Throughout the initial vegetative phase (June-July), the maximum temperature remains 44 °C to 47 °C and may reach up to 49 °C in cotton-growing areas of Pakistan. Heat stress in cotton, like other crops, drastically affects the growth and development of the plants, especially the early reproductive stage (Salman et al, 2019). The most susceptible parts to heat stress in cotton are the flowers and squares.…”

To understand the impact of heat stress on agro-morphological and fiber quality-related traits in cotton, nine locally developed cotton genotypes were grown under heat stress conditions (Late sowing) at the cotton research station, Bahawalpur. Genotypes were laid-out under randomized complete block design (RCBD) in triplicates, where plant to plant and bed to bed distance was maintained as 30 cm and 75 cm, respectively. Data was collected from selected, guarded plants for agronomic as well as fiber quality-related traits. The resultsunveiled the presence of significant variations for studied traits under high temperature conditions. The correlation analysis revealed the significant association of seed cotton yield with plant population (0.403**), monopodial branches per plant (0.267**), fiber strength (0.070*), CLCuV incidence percentage (-0.475**), fiber length (-0.447**), nodes per plant (-0.186*), sympodial branches per plant (-0.186*), and fiber fineness (-0.077*). The multivariate approaches i.e., Principal component, biplot, and cluster analysis classify and characterize cotton genotypes on the basis of their heat tolerance capacity. Moreover, these multivariate analyses showed that BH-377, BH-272, and BH-283 were the most heat tolerant genotypes while BH-283 and BH-284 showed comparatively good CLCuV tolerance. Therefore, these genotypes should be recommended for sowing in heat and CLCuV effected areas of Pakistan after their large-scale, multilocation testing.

“…Any stress during this stage abruptly reduces the yield. Numerous efforts have been made to understand the physiological, molecular, and genetic pathways of the cotton plant related to sustaining yield under stress conditions [3,4]. The reproductive efficiency of the cotton crop is negatively impacted by temperatures above 32 • C in a variety of ways, including reduced metabolism as well as suppression of photosynthesis, pollination, fertilization, and crop growth rate [5].…”

Abiotic stress, particularly heat stress, affects various parts of the cotton plant and ultimately impacts the seed cotton yield. Different portions of a single cotton plant of a cultivar exhibit variable responses to stress during reproductive and vegetative phases. To test this hypothesis, physiological and morphological traits related to heat stress were observed for two flowering positions in 13 genotypes of upland cotton. These genotypes were sown in field conditions in triplicate following a randomized complete block design. Data were collected for pollen germination, pollen viability, cell membrane thermostability, chlorophyll content, boll weight, and boll retention for both the top and bottom branches of each genotype. The collected data were analyzed for the identification of variability within and between genotypes for these two flowering positions. Tukey’s test was applied to estimate the significance of differences between genotypes and positions within each genotype. Results showed that the two positions within the same plant statistically varied from each other. The bottom branches of the genotypes performed significantly better for all traits measured except boll weight. The genotype AA-933 performed best for pollen germination and boll retention, while CYTO-608 exhibited maximum pollen viability in both the bottom and top flower positions compared with other genotypes. Overall, MNH-1016 and CIM-602 showed better cell membrane thermostability and chlorophyll content, respectively. This intra-plant variability can be further exploited in breeding programs to enhance the stress tolerance capabilities of the resulting varieties.
