A detailed knowledge of cell wall heterogeneity and complexity is crucial for understanding plant growth and development. One key challenge is to establish links between polysaccharide-rich cell walls and their phenotypic characteristics. It is of particular interest for some plant material, like cotton fibers, which are of both biological and industrial importance. To this end, we attempted to...

Abstract Background Micronaire is a comprehensive index reflecting the fineness and maturity of cotton fiber. one important internal quality indicators fiber closely related to value Understanding genetic basis micronaire required for improvement trait. However, architecture at genomic level unclear. The present genome-wide association study (GWAS) aimed identify mechanism trait in 83 represent...

In order to determine the relationship between fiber properties of yarn quality in article, experiments were conducted using a passive method mathematical planning and regression equation was obtained for each optimal parameter. Based on experiments, it found that decrease micronaire, an increase tensile strength, length uniformity, leads specific strength yarn, coefficient variation number bre...

The objective of this study was to evaluate a partially introgressed (Gossypiumbarbadense L. × G. hirsutum L.) population of cotton for two years. The traits that studied were lint yield per plant, lint %, fiber length, fiber strength and micronaire. A total of 31 cytogenetically stable lines (2n=4x=52) were produced from a cross between a G. barbadense line, Carnak and a G. hirsutumline, 4S,...

Abstract Background Heterosis has been extensively utilized in different crops and made a significant contribution to global food security. Genetic distance (GD) is one of the valuable criteria for selecting parents hybrid breeding. The objectives this study were estimate GD between using both simple sequence repeat (SSR) markers single nucleotide polymorphism (SNP) investigate efficiency predi...

Nitrogen can be critical in determining fiber yield and quality cotton. Major purpose of this 3-years (2017, 2018, 2019) study Faizabad-Iran was to investigate the effect nitrogen rates, excess on need for maximum its interaction with environment bolls different spatial temporal distribution cotton canopy. Field experiment a split-plot design four replications. Main plots included two rates (LN...

Ten cotton varieties/hybrids with varying properties, such as 2.5% span length measured by HVI, AFIS & Baer Sorter; bundle strength at 3.2mm measured by HVI and Stellometer; and linear density measured by AFIS, HVI and Gravimetric method, have been studied. Maturities are also compared between AFIS and caustic soda methods. In addition, short fibre content measured by HVI, Baer Sorter and AFIS ...

Bioactive gibberellins (GAs) comprise an important class of natural plant growth regulators and play essential roles in cotton fiber development. To date, the molecular base of GAs' functions in fiber development is largely unclear. To address this question, the endogenous bioactive GA levels in cotton developing fibers were elevated by specifically up-regulating GA 20-oxidase and suppressing G...

Genetic variation available for the improvement of fiber properties is restricted in commercial upland cotton (Gossypium hirsutum L.). Resources for fiber improvement exist in G. barbadense L., but introgression of traits has been a limited success. The objectives of this study were to investigate the genetic variation and heritability of agronomic and fiber traits within a diverse recombinant ...
