Citation: Gatica-Palermo, H., Zhang, J., Hughs, S.E., Cantrell, R.G. 2006. Fiber quality and agronomic traits of New Mexico acala cotton released since 1930s: 2005 results. In: Proceedings of the Beltwide Cotton Conferences, January 3-6, 2006, San Antonio, Texas. 2006 CDROM. p. 753-758. Interpretive Summary: Field tests were conducted on 35 recognized 1517 cultivars that had been released from 1930 to the present time. The objective was to evaluate trends of trait inprovements in Acala 1517 cultivars over the past 75 years. It was concluded that yield improvement had occurred during the time by an increase in lint percentage and micronaire, and a reduction in boll and seed size. Traits of fiber length, strength and elongation had also gradually improved over time.
Technical Abstract: Acala 1517 cultivars released from the New Mexico State University cotton breeding program since the 1930s were evaluated in Las Cruces, NM in 2005 for fiber quality and agronomic traits. The study 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. Further tests in more environments will be conducted.
