An Overvew of Breeding for Drought Stress Tolerance in Cotton

Abstract

Drought is a main non-living factor that causes severe crop yield loss globally. Given the strengthening and reappearance of drought events and their impacts, it's important to deepen our understanding as a key to subsidizing mechanisms for drought training and mitigation plans. Pakistan is ranked maximum of the top 5 biggest cotton manufacturers, the seventh largest material producer international, and cotton contributes 10% to the country-wide GDP compared to the overall agriculture area GDP percentage of 18.9%. Cotton farming performs a tremendous role in presenting direct livelihood to 11 million farmers. The cotton crop, in particular, is confined to northern, imperative, and southern zones, with approximately 90 in keeping with cent of the area coming beneath 3 zones. Regardless of this, its cumulative, not apparent impact and multidimensional nature significantly impact the cotton plant’s morphological, physiological, biochemical, and molecular attributes with a detrimental impact on photosynthetic capability. Dealing with water scarcity, plants evolve various complicated resistance and edition mechanisms, including physiological and biochemical responses, which range with species stage. The sophisticated adaptation mechanisms and regularity community that improve the water stress tolerance and version in plants are briefly discussed. Growth pattern and structural dynamics, reduction in transpiration loss via altering stomatal conductance and distribution, leaf rolling, root-to-shoot ratio dynamics, root duration increment, accumulation of like-minded solutes, enhancement in transpiration performance, osmotic and hormonal regulation, and behind-schedule senescence are the techniques that are followed using cotton plant life underneath water deficit. Approaches for drought stress resistance we develop transgenic cotton plants which which can tolerate drought stress to improve cotton quality with good yield.

Heterotic Potential of Upland Cotton Hybrids for Earliness and Yield Related Attributes

“…Utilizing hybrid vigor in industrial cotton production is a popular subject. Pakistan can reap the benefits of cotton heterosis by developing early maturing cultivars and increasing production per acre (Ali et al, 2019;Chaudhary et al, 2019;Khalid and Amjad, 2018;Khalid and Amjad 2019;Malik and Rasheed 2022;Rana et al, 2021). Keeping heterosis in mind, the purpose of the present study is to evaluate the heterosis performance of various yield and earliness-related traits.…”

STABILITY IN YIELD PERFORMANCE EVALUATION OF SELECTED COTTON (Gossypium hirsutum) GENOTYPES IN VARIABLE AGRO-ENVIRONMENTS

“…If any strain or environment with an IPC1 value near zero, it was marked as stable through diverse environments with less contribution towards GEI. Conversely, genotypes bearing high values for IPC1 scores were ranked as explicitly fitted to particular environments (Abdi and Williams, 2010; Askari et al, 2017;Malik and Rasheed, 2022). Accordingly (ENT7) Faisalabad site was high yielding (2532 kg ha -1 ) but with a high IPC1 score (52.18), so ranked an unsuitable site for cotton testing experiments.…”

Mitigation of drought-induced stress in sunflower (Helianthus annuus L.) via foliar application of Jasmonic acid through the augmentation of growth, physiological, and biochemical attributes

“…Under such circumstances, proline and glycine betaine act as osmoprotectants and help in osmotic adjustment by maintaining turgor pressure [ 9 ]. Phenolic content also rises and plays a crucial role as an integral component of the secondary cell wall [ 10 ].…”
