ABSTRACT

In 1991, high volume instrumentation (HVI) was adopted to provide cotton producers and textile manufacturers information on the length, length uniformity, elongation, strength, and micronaire of fiber within every bale of cotton. Studies were conducted in 2002 at the LSU AgCenter, Red River Research Station, Bossier City to evaluate current and obsolete cotton varieties for fiber quality by comparing fiber test results from HVI and less modern fiber testing instruments. Cotton seed of obsolete varieties were obtained from the National Collection of Gossypium Germplasm at College Station, Texas, and seed of newer varieties were obtained from commercial seed companies. Fibers from more modern varieties are longer and stronger than from less recent varieties. Modern varieties also have a higher micronaire than older varieties.
