Acala 1517 cotton cultivars released from the New Mexico State University cotton breeding program since the 1930s were evaluated in Las Cruces and Artesia, NM in 2006 for fiber quality, yield, and agronomic traits. The study in 2005 conducted in Las Cruces, NM confirmed our previous report that yield improvement in Acala 1517 cultivars has been accompanied by an increase in lint percentage and mcironaire (coarser fiber), and reduction in boll and seed size. Fiber length, strength and elongation in Acala 1517 cultivars have been also enhanced over the 70-yr period. This presentation will report the field results collected in 2006 and the combined analysis based on historical data and field performance in two years.
