“…Several factors affect the productivity and fiber quality such as weeds and insect pest (O'Berry et al, 2009;Reeves et al, 2010), soil pH and variation in organic matter content (Johnson et al, 2002;Elms et al, 2001), moisture content and soil fertility (Johnson et al, 1999;Venugopalan and Pundarikakshudu, 1999), and handharvest (Campbell and Jones, 2005), these factors increase the production costs to satisfy the demands and new dynamics on fiber quality by the industry (Campbell et al, 2011;Bourland and Myers, 2015). The development of cotton varieties with high lint yield and excellent fiber qualities has been the major aim of breeding programs, however this is, a big challenge due to the negative association between yield and fiber quality attributes (Constable et al, 2015) by pleiotropic and linkage effects (Bradow and Danidonis, 2000). The progress in the development of superior genotypes would depend upon the nature and magnitude of genetic variation present in the population (Ashokkumar and Ravikesavan, 2011).…”

There is a steady increase of demands for textile crops, where cotton is the most popular natural fiber, therefore, it is necessary to exploit cotton genetic resources. In order to develop and improve crop populations, a cotton breeding program requires access to new sources of germplasm. With the objectives to evaluate the productivity of local and introduced genotypes from Syria and Brazil, and to expand the genetic base in the Venezuelan Cotton Breeding Program, 16 genotypes were evaluated at three locations in Venezuela during 2013 and 2014 using a randomized complete block design, with three replications. The traits evaluated were plant height, stem diameter, lint yield, boll weight, number of seed per boll, 100-seed weight, and fiber content. Highly significant differences (P≤0.01) were observed among genotypes, environments and their interaction for all traits, except for lint yield and number of seed per boll across environments. ʻC-2955-25ʼ showed high yield (3514.3 kg.ha-1) but was unstable across environments used in the evaluation. ʻL-2955-13ʼ was stable across the environments, suggesting that it would be a good parent. All the genotypes obtained values of lint percent above of 38%. The Syrians genotypes ʻAleppo-11ʼ and ʻAleppo-90ʼ showed high lint yield and good agronomic performance. Genotypes identified in this study could be used as potential sources of germplasm to be introduced in future breeding programs.

“…Cotton crop is the main source of pure, natural cellulose fibers which is used to create fabric products. The fruit of the cotton plant is a boll that protects the seeds and cotton fibers, which are soft and delicate (Constable et al, 2014 ). Cotton ( Gossypium spp.)…”

Stable transformation and expression of GhEXPA8 fiber expansin gene to improve fiber length and micronaire value in cotton

et al. 2015

Cotton fiber is multigenic trait controlled by number of genes. Previous studies suggest that one of these genes may be responsible for switching cotton fiber growth on and off to influence the fiber quality produced from a cotton seed. In the present study, the Gossypium hirsutum GhEXPA8 fiber expansin gene was introduced into local cotton variety NIAB 846 by using an Agrobacterium-mediated gene transformation. The neomycin phosphotransferase (NPTII) gene was used as a selection marker for screening of putative transgenic cotton plants. Integration and expression of the fiber expansin gene in cotton plants was confirmed with molecular techniques including Southern blot analyses, real-time PCR. Cellulose assay was used for measurement of cellulose contents of transgenic cotton fiber. The data collected from 3 years of field performance of the transgenic cotton plants expressing GhEXPA8 showed that significant improvement has been made in fiber lengths and micronaire values as compared to control G. hirsutum variety NIAB 846 cotton plants. Statistical techniques were also used for analysis of fiber and agronomic characteristics. The results of this study support improvement of cotton fiber through genetic modification.

“…Irrespective of N supplied, lint quality was within the desired range for micronaire (3.8–4.5), close to the target fiber length of Australian breeding projects (32 mm). and similar to that of premium fiber grown under the same environmental conditions for other fiber quality characteristics (Clement, Constable, & Liu, 2014; Clement, Constable, Stiller, & Liu, 2012; Constable, Llewellyn, Walford, & Clement, 2015).…”

Canopy temperature of high‐nitrogen water‐stressed cotton

et al. 2020

Australian cotton (Gossypium hirsutum L.) farmers are adopting canopy temperature (Tc)‐based irrigation scheduling as a decision support tool to improve on‐farm production. High N supply, characteristic of the high‐yielding, furrow‐irrigated cotton system of Australia, might alter cotton Tc with implications for irrigation. We examined growth, physiological, and biochemical traits and changes in Tc of well‐watered and water‐stressed cotton plants supplied with high to excessive levels of N under glasshouse conditions. We also examined Tc, lint yield, and fiber quality of furrow‐irrigated cotton crop supplied with high N. In the glasshouse and under well‐watered conditions, high N supply stimulated plant growth and increased stomatal conductance and photosynthesis, resulting in cooler Tc. Under water deficit stress, high N also stimulated growth, increasing plant water demand and thus vulnerability to water stress, which manifested as warmer Tc. Water‐stressed plants supplied high N also showed reduced stomatal conductance, lower leaf water potential, and greater accumulation of leaf and xylem sap abscisic acid. Furrow‐irrigated crops supplied higher N also had higher Tc, but there was no gain in lint yield and fiber quality. The influence of high N on cotton Tc suggests that the need for accurate and reliable Tc‐based irrigation scheduling is paramount.
