Description	UA212ne is a nectariless (absence of nectaries on all plant parts) cotton with other morphological traits similar to ‘DP 393’ (check cultivar), except UA212ne has lower trichome density on abaxial leaf surface and bract margins. Over 4 years of replicated field tests at four sites in Arkansas, lint yields of UA212ne were equal to lint yields of DP393 on Sharkey clay soil at Keiser (north) and on silt loams at Judd Hill (north) and Rohwer (south), but were 25.2% than DP 393 on silt loam soils at Marianna (central delta) and 8.4% higher over all four locations. Compared to DP 393, lint yields of UA212ne were produced with equal number of seed per area, but higher weight of lint per seed (lint index), fibers per seed, and fiber density (estimated number of fibers per unit area of seed surface). Compared to DP 393, UA212ne produced higher lint percentage (42.2 vs 39.5%), lint index (8.0 vs. 7.6 g), fibers per seed (9.8% higher), and fiber density (14.9% more fibers per unit area of seed coat); equal seed per area, open boll percentage (maturity), plant height, stem pubescence rating, fiber uniformity index, fiber strength, and fiber elongation; and lower seed index (10.7 vs. 11.3 g), leaf pubescence rating (3.5 vs. 3.9), marginal bract trichome density (26.5 vs. 35.7 trichomes cm -1 ), and fiber micronaire (4.51 vs. 4.81). UA212ne is resistance to all U.S. races of Xanthomonas citri ssp. malvacearum (ex Smith 1901) Schaad et al. 2007, the causal agent of bacterial blight. UA212ne had lower damaged flowers than DP 393 (51 vs. 55%) in tests of resistance to tarnished plant bug [Lygus lineolaris (Palisot de Beauvois)]. As indicated by visual ratings and lint yield at Judd Hill location (site of high Verticillium wilt), response of UA212ne to Verticillium wilt [caused by Verticillium dahliae Kleb] was equal to DP 393.Note: Plants, from which seed were produced, were evaluated and determined to be free of Bt (BG1 and BGII) and RR Flex transgenes.
