“…Genetic variability in physiological, reproductive traits, lint yield, and fiber quality in cotton is evident in cotton, indicating the potential to increase stress tolerance [24,25]. To date, selections have been focused on yield and fiber quality traits to develop progenitors of G. hirsutum from its wild relatives [26] for non-stress conditions.…”

Upland cotton (Gossypium hirsutum L.) growth and development during the pre-and post-flowering stages are susceptible to high temperature and drought. We report the field-based characterization of multiple morpho-physiological and reproductive stress resilience traits in 11 interspecific chromosome substitution (CS) lines isogenic to each other and the inbred G. hirsutum line TM-1. Significant genetic variability was detected (p < 0.001) in multiple traits in CS lines carrying chromosomes and chromosome segments from CS-B (G. barbadense) and CS-T (G. tomentosum). Line CS-T15sh had a positive effect on photosynthesis (13%), stomatal conductance (33%), and transpiration (24%), and a canopy 6.8 °C cooler than TM-1. The average pollen germination was approximately 8% greater among the CS-B than CS-T lines. Based on the stress response index, three CS lines are identified as heat- and drought-tolerant (CS-T07, CS-B15sh, and CS-B18). The three lines demonstrated enhanced photosynthesis (14%), stomatal conductance (29%), transpiration (13%), and pollen germination (23.6%) compared to TM-1 under field conditions, i.e., traits that would expectedly enhance performance in stressful environments. The generated phenotypic data and stress-tolerance indices on novel CS lines, along with phenotypic methods, would help in developing new cultivars with improved resilience to the effects of global warming.

“…Information on the effects of deficit irrigation on crop performance can assist producers with making informed decisions on the appropriate levels of deficit irrigation that would result in their desired water conservation and yield goals (Chen et al, 2020). Field studies that optimize irrigation water conservation are particularly important in cotton production due to its global importance (Himanshu, Ale, Bordovsky, & Darapuneni, 2019;Mitchell-McCallister et al, 2020;Ulloa, De Santiago, Hulse-Kemp, Stelly, & Burke, 2020). However, several such studies have found mixed results of the response of cotton yield and fiber quality to different levels of irrigation.…”

Water scarcity threatens the sustainability of irrigated cotton production in many regions around the world. Consequently, there is a critical need to identify and test strategies that optimize water use for cotton production. This 4-yr study evaluated the effects of three irrigation treatments (full irrigation [FI], reduced irrigation [RI] at 75% of FI, and no irrigation [NI]) on cotton yield, fiber quality, and irrigation water use efficiency (IWUE) at a field that relies on groundwater for irrigation in west-central Oklahoma. Compared with FI, lint and seed yields did not change significantly under RI. The reductions in lint and seed yields were significant at 64 and 65% under NI, respectively, compared with FI. No significant differences in fiber quality were observed among the irrigation treatments. In addition, reducing irrigation application improved the IWUE of lint and seed by 9 and 8%, respectively. Based on these findings, reducing groundwater extraction by 25% appears to be an effective strategy to achieve water conservation while limiting negative impacts on yield quantity and quality for cotton production in west-central Oklahoma.

“…It was further observed that effect of drought stress on number of bolls, boll weight and seed cotton yield was greater than that on other traits. Previously, similar responses in these traits were studied in water stressed plants of Pennisetum glaucum and cotton (Shakoor et al, 2010;Ulloa et al, 2020). Like morphological parameters, excised leaf water loss and relative water content, differentiated drought stress tolerant and sensitive genotypes.…”

The limited water supply for irrigation is a major constraint to cotton production. Morphological and physiological traits provide useful information for drought tolerance. This research work was carried out for the identification of cotton genotypes having better drought tolerance. For this purpose, forty (40) genotypes of upland cotton were studied under two moisture regime, i.e. normal and drought environment in field conditions. The experiment was conducted using split plot design under RCBD arrangement. All the genotypes behaved differently under two moisture levels. The interaction of cotton genotypes with two moisture levels were studied for various traits, i.e. plant height, sympodial branches, seed cotton yield, boll weight, number of bolls per plant, excised leaf water loss and relative water content by using Principle Component Analysis (PCA). Results showed that the genotypes VH-144, IUB-212, MNH-886, VH-295, IR-3701, AA-802, NIAB-111, NS-121, FH-113, and FH-142 are either stable or showing positive interaction with drought conditions for most of the traits under studied. These genotypes can be used in further breeding program for developing varieties suitable for cultivation under drought conditions, whereas; IR-3, CIM-443, FH-1000, MNH-147, S-12 interacted undesirably with drought stress
