2013 Annual Report
Also, an F2 hybrid half-diallel developed using the same 11 near extra long staple cotton accessions will be evaluated in replicated trials in South and North Carolina. Evaluation of this half-diallel population will be used to determine the extent of fiber property genetic variation among the 11 near extra long staple cotton accessions.
To meet current and perceived future market demands, cotton breeding programs must increase fiber quality potential and provide this potential to growers via new, high quality cultivars. The primary objective of this cooperative research project is to develop breeding populations derived from high fiber quality near-ELS germplasm. During the first year of this project (2012), a preliminary analysis of agronomic data suggested that most near-ELS accessions result in breeding populations with low lint percent. However, a number of near-ELS derived breeding populations had competitive lint yields. In the current project (2013), the second year of a replicated yield trial is being conducted. Agronomic and fiber quality data will be collected during 2013. Information will be provided to the cotton breeding community on the feasibility of using near-ELS germplasm in order to develop high yield and quality cultivars that meet international market demands.
