- Abstract
This article presents information on the registration of 14 primitive derived cotton germplasm lines with improved fiber strength. The ARS-U.S. Department of Agriculture and the Mississippi Agricultural and Forestry Experiment Station released 14 primitive derived cotton germplasm lines with improved fiber strength in 2004. These lines were derived from photoperiodic primitive race accessions that were converted to day-neutrality and selected for improved fiber strength. The lines were derived from day-neutral selections from crosses of cultivars with day-length sensitive primitive race accessions. M1388-1, M1388-2, and M1388-3 were developed from a cross between DES56 and accession T1388. The germplasm lines generally had lower yield and lint percentage compared with check cultivars. Except for M75-1, M1388-2 and -3, and M237-2 boll weights were comparable to checks. Micronaire reading for M237-1, -2, and -3 was lower than checks while other germplasm lines were equal or higher than check cultivars. Percentage fiber elongation was lower than cultivars except for M75-1, which was equal to checks.
