The Growth and Yield of Acala Cottons Developed in New Mexico

An experiment was conducted in 2008 to evaluate the growth and yield of 18 Acala cotton cultivars developed in New Mexico from 1923 to present. A randomized complete block design with two (for growth measurements) or three replications (for yield determination) was employed. Plant growth rates tended to be higher on lately developed Acala cultivars. Boll size tended to be smaller for Acala cotton developed after 1965. Interestingly, two early cultivars Acala 1517C and 1517E2 showed higher lint cotton yield than 1517-99.
