Narrative
Arkot 1114 is a conventional cotton germplasm line with morphological traits similar to ‘UA222’ (check cultivar), except Arkot 1114 has slightly lower pubescence on stems and greater trichome density on bract margins. Lint yields of Arkot 1114 from replicated field tests at four sites in Arkansas over five years were equal to or greater than lint yields of UA222 and exceeded those ‘UA48’ (check cultivar) at each location. Over all locations, lint yields of Arkot 1114 were 13.0 and 23.7% greater than UA222 and UA48, respectively. Soils at all sites are silt loams, except the Sharkey clay at Keiser. Compared to UA222, Arkot 1114 produced higher lint fraction (42.7 vs. 40.5%), seed ha-1 (18607 × 1000 vs. 16776 × 1000), fibers per seed (16696 vs. 16105), fiber density (168 vs. 152 fibers mm-2 of seed coat), open boll percentage (54 vs. 49%), marginal bract trichome density (48 vs. 40 trichomes cm-1), and quality score (57 vs. 53); equal plant height (92 vs. 94 cm), seed-score (68.8 vs. 73.4), leaf pubescence rating (5.6 vs. 5.5), fiber length (31.6 vs. 31.6 mm), fiber uniformity index (85.5 vs. 85.5%), and short fiber content (6.2 vs. 6.0%); lower seed index (9.6 vs. 10.7 g), lint index (7.4 vs. 7.6 g), stem pubescence (5.7 vs. 6.2 rating), fiber micronaire (4.21 vs. 4.45), fiber strength (299 vs. 316 kN m kg-1), and fiber elongation (5.3 vs. 7.3%). Arkot 1114 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. Damaged flowers for Arkot 1114 (65%) was lower than the susceptible check (92%), equal to UA48 (65%), and higher than UA222 (54%) in tests of resistance to tarnished plant bug [Lygus lineolaris (Palisot de Beauvois)]. Resistance to seed deterioration of Arkot 1114 was lower than UA222 and UA48.
