The term ‘‘micronaire” describes an important cotton fiber property by characterizing both the fibermaturity and fineness. In practice, micronaire is regularlymeasured in laboratories with the well established high volume instrumentation (HVI) protocol. In most scenarios, cotton breeders/geneticists sent cotton breeding line field trial samples to laboratories equipped to use the HVI systems av...

With the focus that short fiber content in cotton receives from textile mills, there is a need to improve the precision and accuracy of this measurement. In order to do this, it is necessary to understand the opportunities that exist to improve the measurement of short fiber. Since the Advanced Fiber Information System (AFIS) is the most widely recognized method for determining short fiber cont...

High volume instrumentation (HVITM) measurement is a primary and routine tool of providing fiber properties to cotton researchers. There have been considerable studies designed to derive yarn quality from acquired fiber quality data by various means, including HVI. There is also of desired information about the comparison of yarn quality within a cotton cultivar or among the cultivars, as such ...

Reflectance spectra of cotton fiber samples having different fiber quality levels were measured with a high‐resolution spectrophotometer, processed with waveband averaging and wavelet analysis, and then related to micronaire with multiple linear regression. Regression models indicated that micronaire had a close relationship (R2 = 0.89) with reflectance at seven 100 nm wavebands (1120, 1296, 15...

Wanjura, D.F. and Barker, G.L., 1985. Cotton lint yield accumulation rate and quality development. Field Crops Res., 10: 205--218. Crop production management during the period of boll setting and maturation of cot ton (Gossypium hirsutum L.) is critical in determining lint yield and quality. A field investigation conducted at Lubbock, Texas, during 1977--1980 included three cultivars to study t...

The aim of this study was to determine the general combining ability (GCA) parents and specific their hybrid combinations evaluate vigor F1 by investigating genetic structure lines testers. carried out in randomized complete blocks design with three replications trial site Nazilli Cotton Research Institute 2015 2016 years. 28 hybrids (4 7 testers) were used as material which developed from line...

Cotton (Gossypium hirsutum L.r. latifolium Hutch) is very sensitive to soil conditions. The Iuiu Valley, located in the Southwest of Bahia State in Brazil, was an important area for cotton production but an inadequate soil management for years and consequent soil quality degradation lead to the decline of the crop in the region. In an effort to reestablish cotton, this study was carried out to ...

Interspecific chromosome substitution is among the most powerful means of introgression and steps toward quantitative trait locus (QTL) identification. By reducing the genetic "noise" from other chromosomes, it greatly empowers the detection of genetic effects by specific chromosomes on quantitative traits. Here, we report on such results for 14 cotton lines (CS-B) with specific chromosomes or ...
