    Among the genotypes in PC 1 are poor in fiber strength. Fiber elongation and fiber fineness were affected due to effect of rain. Number of bolls, seed cotton yield, lint index, seed index, GOT%, fiber strength and fiber have positive effects, these results are in the line of [12]. Yield parameters in PC 1 have positive effects. The traits Cited by: 1.   This study was conducted to investigate the effect of heterogeneity and heterozygosity on lint yield and fiber quality of Egyptian cotton for late planting stress tolerance. Lint yield was recorded in two planting dates among four cotton population types which included homozygous lines grown in pure stands, hybrids grown in pure stands, homozygous lines in Author: Khaled M. A. Baker, Sara E. I. Eldessouky.

    Goals / Objectives (1) Evaluate the adaptation of new commercial cotton varieties to the field production environments of Tennessee in terms of yield potential, earliness of maturity, fiber quality, and yield stability; (2) Determine the physiological efficiency, economic potential and agronomic components of alternative cropping systems, such as ultra-narrow-row (UNR) cotton . Nitrogen fertility is an important component of irrigated, short‐season cotton (Gossypium hirsutum L.) production and is necessary to achieve optimum yield. .

    cotton fiber strength has been shown to be associated with the molecular weight of the and finally tensile properties of fibers are reviewed in this book. Topics such as single fiber tensile properties, tensile properties of fibers with high between fiber They specifically reviewed the studies on tensile properties of individual cottonCited by: 5.   However, the fiber of “extra-long-staple” G. barbadense tetraploids, representing ∼5% of the world’s cotton, commands a premium price due to ∼40% higher fiber length (≈35 mm), strength (≈30 g per tex or more), and fineness over leading A genome cultivars, at similar yield Cited by:

Narrow rows gave no differences in total yield, earliness, lint percent, fiber length, or strength resulting from row patterns or plant populations.

The highest plant population gave more blooms in twin cm rows, but not in cm rows. The most significant challenge for cotton breeders has been to combine earliness and fiber strength of blends of cotton book yield with improved fiber quality, due to negative associations between yield and quality attributes in G.

hirsutum. Cotton fiber length is measured and reported as the upper half mean length (average length of the longest 50% of fibers) to an accuracy of one hundredth of an inch. Cotton Fiber Strength Fiber strength is measured by breaking the fibers held between clamp jaws.

It’s reported as grams per tex, which is the force in grams required to break a. Useful qualitative results can be obtained if we consider model bundles consisting of five fibers with different strengths. Five such bundles are presented in Table showing the normalized strength of each fiber.

As can be seen, the deviation of fiber strength is such that the mean strength, σ ¯ m = 1, is the same for all the bundles, whereas the variation coefficient, r σ. fiber-quality ranges that can occur within the bales or the resulting blends.

Further, the natural variability among cotton fibers unpredictably reduces the processing success for blends made up of low-priced, lower-quality fibers and high-priced, higher-quality fibers. Blends that fail to meet processing specificationsCited by: Tensile Strength: Cotton is moderately strong fiber.

It has a tenacity of gm/den. The strength is greatly affected by moisture; the wet strength of cotton is 20%, which is higher than dry strength.

Elongation at break: Cotton does not stress easily. It has an elongation at break of %. Elastic Recovery: Cotton is inelastic and rigid.

Cotton plants in both systems produced approximately 75% of total lint in the first two harvests, indicating no significantly delayed earliness in LPPS relative to NPPS.

Fiber from late-season bolls exhibited reduced strength and micronaire in both systems, but there were no significant differences in fiber properties for early- and mid-season Cited by: Blends of different cotton fiber types and blends of polyester and cotton fibers are evaluated using a number of analytical methods such as the torque profile during opening and blending, the Author: Mounir Hassan.

The effects of the super okra leaf shape on boll rot. yield, plant and fiber characters of Upland cotton, Gossypium hirsutum L., were investigated at three locations in Louisiana. Near isogenic populations of super okra leaf and normal leaf on each of three varietal backgrounds were used.

Correlated responses to selection for yield were observed for the majority of the unselected traits measured. As selection increased lint yield, simultaneous increases were observed for lint percentage, number of seed per boll, earliness, fiber elongation, and fiber coarseness.

Boll size, seed size, and fiber length and strength decreased. Abstract. Selection experiments are usually conducted in one or two directions, whereas studies involving multidirectional selection are rare.

This multidirectional selection experiment for T 1 fiber strength was conducted through five cycles within a genetically variable population of upland cotton (Gossypium hirsutum L.) to investigate the direct and correlated responses to selection.

A field trial was conducted to determine the effects of phosphorus (P) levels (0, 30, 60 and 90 kg ha -1) on growth and yield components in cotton cultivars (CIM, MNH.

MD15 in this study consisted of the average performance of four F lines. All four of these lines descended from selfed seed of one F2 plant from the cross of FM and MD51neOK.

The F2 plant progeny number showed superior fiber strength (Meredith, ).Cited by: 9. The cotton polyester blend was mixed with [DBNH] [OAc] (1 h, 80 °C) using a vertical kneader system (cf. experiments [S1], [S2], and [M2] in Table 1) to yield a cellulose solution of w%.

The economic significance of cotton in the global market is evident by its majority share (over 50%) among fibers for apparel and textile goods.
