Interpretive Summary: Genotypic and environmental contributions to fiber quality have been studied considerably in cotton industry for a long period, but little information exists regarding the variation and relationship of fiber and yarn qualities or the compositional and structural similarity of cottons harvested from different environments. This study examined the relationships between HVITM and AFIS fiber qualities and Skein yarn spinning performance of cottons from multi-location field performance trials, and also interpreted the NIR spectral response to these cottons through principal component analysis. The outcome provides cotton fiber / textile engineers and breeders a new sight in understanding the relationship among cotton fiber / yarn quality, fiber compositional and structure variation, and growing locations.
Technical Abstract: High volume instrumentation (HVITM) and advanced fiber information system (AFIS) measurements are increasingly being utilized as primary and routine means of acquiring fiber quality data by cotton breeders and fiber processors. There is amount of information regarding fiber and yarn qualities, but little information exists about the compositional and chemical structure difference of cotton fibers harvested at different locations. Such information could prove useful in attempt to understand the variety selection of cotton cultivars. The purpose of this study was to characterize the fiber HVITM and AFIS quality and also yarn Skein strength of cottons harvested from various locations, and also to unravel the NIR spectral response to these differential environments. Moderate positive or negative relationships among fiber properties were observed. However, these relationships varied across experimental locations and years. Further, the analysis of ANOVA variance tests indicated substantial variations among genotypes for fiber properties, but less detectable variation among genotypes for yarn tenacity. Interestingly, principal component analysis of NIR spectra enhanced the similarity or dissimilarity of cotton fibers harvested at differing locations, implying the feasibility of NIR technique for site selection in future cotton variety trials.
