'UA48' (Reg. No. CV-129, PI 660508) is a conventional cultivar of cotton (Gossypium hirsutum L.), that was released by the Arkansas Agricultural Experiment Station in November 2010. Parents of UA48 included Arkot 8712 and FM 966. UA48 was released as part of an ongoing effort to develop improved genotypes having enhanced yield, yield components, earliness, host-plant resistance, and fiber properties. In most tests, UA48 had a lint yield comparable to that of DP 393, a well-adapted conventional cultivar. It appears to be best adapted to silt loam soils in the northern areas of U.S. cotton production. UA48 matures as early as any cultivar that is adapted to the Mississippi River Delta. It displays high resistance to bacterial blight and is equal to DP 393 in its response to other diseases. Fiber quality of UA48 is exceptional. In most tests, its fiber length, length uniformity, and strength exceeded most, and frequently all, other entries. Its micronaire is comparable to DP 393. UA48 displays an unusual combination of high yield, early maturity, and high fiber quality. © Crop Science Society of America.

Arkot 0015a (Reg. No. GP-935, PI 660505), Arkot 0015b (Reg. No. GP-936, PI 660506), and Arkot 0016 (Reg. No. GP-937, PI 660507) are noncommercial breeding lines of cotton (Gossypium hirsutum L.) that were released by the Arkansas Agricultural Experiment Station in August 2010. All three lines were released as part of an ongoing effort to develop improved germplasm lines having enhanced yield, yield components, earliness, host-plant resistance, and fiber properties. Both Arkot 0015a and Arkot 0015b were derived from the cross of two advanced breeding lines: Ark 9308-14 and Ark 9409-22. Arkot 0016 was derived from a cross of Ark 9308-14 and Arkot 9101. The three lines were evaluated in replicated tests at four Arkansas sites from 2006 through 2009. Compared with 'DP 393', Arkot 0015a and Arkot 0016 tended to produce lower lint yields and enhanced yield components and to have similar maturity and better fiber quality. Lint yields, maturity, and fiber quality of Arkot 0015b were similar to those of DP 393. Except for Arkot 0016 having the highest density of trichomes on its leaves, all three lines had a lower or equal trichome density on their leaves, stems, and bracts than DP- 393. Lower trichome densities are associated with less trash and higher grades of cotton lint. The three lines are resistant to bacterial blight [caused by Xanthomonas campestris pv. malvacearum (Smith) Dye]. Resistance of the lines to tarnished plant bug [Lygus lineolaris (Palisot de Beauvois)] was equal to that of 'SG 105' and lower than that of DP 393. The relative yield, maturity, and line-specific host-plant resistance traits make these lines valuable to cotton breeding programs. © Crop Science Society of America.

A potentially environmentally responsible dyeing procedure for ultra-deep shades on cotton was developed using a cationization method in combination with mercerization. The effects of both treatments on dyeing performance and colorfastness properties of cotton fabrics dyed with reactive dyes were analyzed individually and in combination. Both mercerization and cationization have been proved to be effective in increasing the depth of shade on cotton. The colorfastness properties, except colorfastness to wet crocking, of mercerized-cationized cotton fabrics dyed without salt were much better than untreated cotton dyed using a conventional dyeing procedure. Unlike untreated cotton fabrics, the concentration of Na2CO3 in the dyeing process of mercerized-cationized cotton fabrics was lowered from 20 to 5 g/L without compromising dye fixation and colorfastness properties. With low concentrations of dyes and Na2CO3 and no electrolyte in the dye bath effluent, the dyeing procedure of mercerized-cationized cotton fabrics for ultra-deep shades is potentially a more environmentally benign method than conventional dyeing with reactive dyes. © 2013 Springer Science+Business Media Dordrecht.

CottonGen (http://www.cottongen.org) is a curated and integrated web-based relational database providing access to publicly available genomic, genetic and breeding data for cotton. CottonGen supercedes CottonDB and the Cotton Marker Database, with enhanced tools for easier data sharing, mining, visualization and data retrieval of cotton research data. CottonGen contains annotated whole genome sequences, unigenes from expressed sequence tags (ESTs), markers, trait loci, genetic maps, genes, taxonomy, germplasm, publications and communication resources for the cotton community. Annotated whole genome sequences of Gossypium raimondii are available with aligned genetic markers and transcripts. These whole genome data can be accessed through genome pages, search tools and GBrowse, a popular genome browser. Most of the published cotton genetic maps can be viewed and compared using CMap, a comparative map viewer, and are searchable via map search tools. Search tools also exist for markers, quantitative trait loci (QTLs), germplasm, publications and trait evaluation data. CottonGen also provides online analysis tools such as NCBI BLAST and Batch BLAST. © 2013 The Author(s). Published by Oxford University Press.

Since the recent Deepwater Horizon Gulf of Mexico oil spill, the need for environmentally friendly oil sorbents has intensified. This study deals with the sorption of crude oil by raw cotton, a biodegradable sorbent. To our best knowledge, the data related to crude oil sorption by unprocessed raw cotton and correlation with cotton characteristics such as micronaire, fineness, and maturity are unavailable. More importantly, our work quantifies the oil sorption (g/g) of low micronaire (immature) cotton. Results showed at the minimum level, low micronaire raw cotton has 30.5 g/g crude oil sorption capacity. Furthermore, the crude oil sorption capacity of low micronaire cotton was significantly higher than the sorption capacity of high micronaire cotton. Brunauer-Emmett-Teller (BET) surface area and environmental scanning electron microscopy analyses support the correlation between the quality characteristics of raw cotton and its oil sorption capacity. In contrast to synthetic sorbents, raw cotton with its high crude oil sorption capacity and positive environmental footprint make it an ecologically friendly sorbent for oil spill cleanups. © 2013 American Chemical Society.
