The harmonic mean of the relative performance of genotypic predicted value (HMRPGV) method has been used to measure the genotypic stability and adaptability of various crops. However, its use in cotton is still restricted. This study aimed to use mixed models to select cotton genotypes that simultaneously result in longer fiber length, higher fiber yield, and phenotypic stability in both of the...
Within the framework of our cotton breeding program, we are using molecular markers to improve the efficiency of the introgression of fiber quality traits into a favorable genetic background. This effort relies on i) the development of a saturated genetic map of the cotton genome, ii) the identification of fiber quality QTLs, and iii) the marker-assisted introgression of favorable genomic regio...
Of the two cultivated species of allopolyploid cotton, Gossypium barbadense produces extra-long fibers for the production of superior textiles. We sequenced its genome (AD)2 and performed a comparative analysis. We identified three bursts of retrotransposons from 20 million years ago (Mya) and a genome-wide uneven pseudogenization peak at 11-20 Mya, which likely contributed to genomic divergenc...
World textile fiber demand was 89.8 million tons in 2015 and is expected to grow to 93.7 million tons in 2016. Global demand for textile fibers is driven by population growth and by economic activity resulting in increasing wealth, particularly in emerging economies. While this overall trend is consistent across most major fibers, there are substantial disparities in the demand patterns of natu...
Cotton (Gossypium hirsutum L.) boll positions on a fruiting branch vary in their contribution to yield and fiber quality. Fiber properties are dependent on deposition of cellulose in the fiber cell wall, but information about the enzymatic differences in sucrose metabolism between these fruiting positions is lacking. Therefore, two cotton cultivars with different sensitivities to low temperatur...
Hemp fiber is obtained from the plant Musa textilis. The cost of preparation of its raw fibers is low. The purpose of this paper was to compare the inflammatory response in the rat muscle tissue originated by both hemp and cotton fibers. Both types of fibers, were implanted in gluteal muscles of Sprague Dawley rats. The rats were sacrificed at 15, 30 and 60 postoperative days. Muscle tissue sec...
Damage to cotton by micro-organisms causes a serious loss to the cotton farmer, manufacturer, and consumer. For this reason studies are in progress in the Department of Agriculture on the growth and effect of various micro-organisms which cause deterioration of cotton. In an earlier investigation in this laboratory by Rogers, Wheeler, and Humfeld (1940) the growth of Chaetomium globosum Kunze o...
Cotton fiber is an ideal model for studying plant cell elongation. To date, the underlying mechanisms controlling fiber elongation remain unclear due to their high complexity. In this study, a comparative proteomic analysis between a short-lint fiber mutant (Ligon lintless, Li(1)) and its wild-type was performed to identify fiber elongation-related proteins. By 2-DE combined with local EST data...
Fiber quality improvement is a driving force for further cotton domestication and breeding. Here, QTLs for fiber quality were mapped in 115 introgression lines (ILs) first developed from two intraspecific populations of cultivated and feral cotton landraces. A total of 60 QTLs were found, which explained 2.03-16.85% of the phenotypic variance found in fiber quality traits. A total of 36 markers...
