Technical Abstract: Yarn tenacity affects textile processing speed and the type and quality of textile product that can be made. Cotton fiber properties such as strength, length, fineness, and short fiber content affect yarn tenacity and quality. Various instruments are available to breeders to measure fiber properties, but few studies have compared heritability and selection response among instruments. Heritability of fiber properties was generally similar between single and HVI instruments except for fiber length and strength. Heritability of HVI-measured fiber length was slightly greater than that measured with the fibrograph; heritability of fiber strength by stelometer measurement was greater than that measured with HVI. Yarn tenacity of the poulation selected for fiber strength by stelometer was slightly greater than that selected on the basis of HVI strength. Choice of instrument with which to measure fiber properties will have to consider the reduced cost of HVI measurement against the greater gain in yarn tenacity with stelometer measurement.
