Objective:
Develop Upland cotton breeding populations using near-extra-long staple (ELS) germplasm.

Approach:
In 2013, the second year of a topcross test, derived from 11 near extra long staple cotton accessions and 5 elite germplasm lines, will be evaluated in replicated trials in South and North Carolina. Similar to 2012, yield, yield components, and high volume instrument (HVI) fiber properties will be collected and analyzed to determine estimates of general and specific combining ability for each cross combination. F3 progeny rows from selected F2 hybrid populations will be integrated into the progeny row nursery evaluation of the breeding program. 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.
