“…Previous studies indicated that immature fibers break during processing [30][31][32][33]. In this study, it appears that the effect of Verticillium wilt results in poor development of secondary cell walls, rendering them weak and with a propensity to break during mechanical processing and create higher short fiber content.…”

Verticillium wilt, caused by Verticillium dahliae Kleb., leads to significant losses in cotton yield and fiber quality worldwide. To investigate Verticillium wilt impact on photosynthesis rate, yield, and fiber quality, six upland cotton genotypes, namely Verticillium susceptible (DP 1612 B2XF) and partially resistant (FM 2484B2F) commercial cultivars and four breeding lines, were grown to maturity under greenhouse conditions in soil either infested or not infested with V. dahliae microsclerotia. Photosynthetic rate, lint, and seed yield were all higher (p < 0.05) for FM 2484B2F than DP 1612 B2XF when infected with V. dahliae. When comparing healthy (H) to Verticillium wilt (VW) affected plants, fiber properties were greatly impacted. Micronaire decreased from 5.0 (H) to 3.6 (VW) with DP 1612 B2XF and 4.4 (H) to 4.1 (VW) with FM 2484B2F. The maturity ratio decreased from 0.90 (H) to 0.83 (VW) for DP 1612 B2XF and was unchanged for FM 2484B2F (0.90). Fiber properties such as short fiber content, nep count, fineness, and immature fiber content were also significantly affected under Verticillium wilt pressure. With Verticillium wilt affected plants, lines 16-13-601V and 17-17-206V performed similarly to FM 2484B2F for photosynthetic rate, yield, and all fiber properties measured. When selecting for improved cultivars in the presence of Verticillium wilt, it is important to select for relatively unchanged fiber properties under disease pressure in addition to reduced disease severity and increased yield.

“…Additionally, growth conditions have an impact on the within-canopy variation of fiber quality, in particular on fiber maturity distribution (Ritchie et al, 2004;Feng et al, 2011). Fiber maturity is one of the most important fiber quality parameters as it has a potential impact on different fiber properties including fiber length, strength, the linear density of fiber or fineness, and other yield components such as cotton fiber density (Ayele et al, 2017). Hequet et al (2006) suggested that when conditions are optimal during plant growth, most of the fibers could reach their full maturity level, while fibers developing under less optimum conditions will not reach full maturity.…”

“…Particularly, fibers contributed by the top of the plant tend to be less mature. Immature fibers with poorly developed secondary cell walls are weak and have the propensity to break more easily during mechanical processing Abidi and Hequet, 2006;Ayele et al, 2017), creating high short fiber content that leads to more fiber-to-fiber variability within a bale of cotton. Kelly et al (2015) suggested that fiber quality is at its best before the boll opens.…”

“…Therefore, the objective of this study is to evaluate the extent of within-plant variability of fiber length and maturity of 12 upland cotton cultivars popular in the Texas High Plains. Box Picking, Ginning, and Blending The within plant distribution of fiber quality for each cultivar was captured using a box picking harvesting method following Bednarz et al, 2006;Feng et al (2011);and Ayele et al (2017). The grid box divides cotton bolls by main-stem node and fruiting positions.…”

“…High withinplant variability of fiber length previously discussed may be related to high within-plant variability in fiber maturity. It has been reported that less mature fibers tend to be prone to breakage when submitted to mechanical stress, creating short fibers which negatively impact mean fiber length (Kothari et al, 2015;Ayele et al, 2017).…”

A gronomy J our n al • Volume 110 , I ssue 1 • 2 018 47 D uring the past two decades, international demand for high cotton fi ber quality has increased because of the dominance of ring-spun yarn production. We hypothesized that minimizing the variability of cotton fi ber quality among fi bers within-bale could contribute to better spinning performance and yarn quality resulting in a better end-product with a lower cost of production. Th e variability in physical attributes among cotton fi bers within a bale has been shown to aff ect textile manufacturing effi ciency and the quality of the fi nished textile products (Smith and Cothren, 1999;Krifa, 2012). Cotton fi ber quality is naturally variable within a single seed, within a single boll, within the plant, and within the fi eld. Th ese sources of variability in fi ber quality contribute to within-bale fi ber-to-fi ber variability. One of the potential strategies to minimize the variability of fi ber quality among fi bers within a bale of cotton is to optimize the within-plant variability of cotton fi ber quality.Within-plant variability of cotton fi ber quality is determined by many factors, including the growth habit of the cotton plant, genetics, and environmental conditions during cotton fi ber development (Stewart, 1975;Faulkner et al., 2011;Kothari et al., 2015). Th e indeterminate fruiting habit of the cotton plant provides a signifi cant source of within-plant variation in cotton fi ber quality. American upland cotton is a highly indeterminate, perennial plant, which is grown in an annual cropping system (Lewis, 2002;Oosterhuis and Cothren, 2012). Cotton plants set fl owers in a predictable pattern. Along the main axis, the setting of fl owers occurs at the same fruiting position in 3-d intervals. Bolls set at each position along a single fruiting branch are set approximately 6 d apart (McClelland, 1916;Lewis, 2002). Th ree days aft er the fi rst fl ower sets in position one, the fi rst position boll on the next vertical node sets (Meredith and Bridge, 1973). Th is pattern is used for estimating relative diff erences in boll ages (Baker and Baker, 2010).Cotton plants set the fi rst position bolls at the bottom parts of the plants early in the season compared to bolls setting at the apical and distal positions. Bolls sets in the lower half of the plant and fi rst fruiting position bolls have more time and resources to develop mature fi bers. ABSTRACTPrevious studies have indicated diff erences in fi ber quality parameters including fi ber length and maturity within the canopy of cotton (Gossypium hirsutum L) plants. A 3-yr study was conducted to investigate the impact of within-plant variability on fi ber length and maturity of upland cotton cultivars widely grown on the High Plains of Texas. Twelve upland cotton cultivars were grown in a randomized complete block design with three fi eld replications, in Lubbock, TX, during the 2012, 2013, and 2014 growing seasons. A box-picking harvesting method was used to individualize samples so that the within-plan...
