El Dorado Acala is a new cotton from J. G. Boswell Cottonseed Breeding. To examine the unique fiber and spinning properties of this variety, El Dorado was compared to Acala Maxxa (the San Joaquin Valley standard cotton variety). Samples of the two cottons were obtained from replicated trials conducted over a three year period in the San Joaquin Valley. El Dorado was found to exhibit significantly better fiber uniformity, strength, and elongation than Maxxa. Despite reduced fiber length (ITC test) and elevated micronaire, El Dorado produced superior yarns compared to Maxxa, with lower manufacturing waste. El Dorado yarns showed improved strength, tenacity, elongation, evenness, and had fewer neps than Maxxa yarns.
