Narrative
Morphological traits of Arkot 0611 are similar to 'DP 393' (check cultivar), except trichome density of Arkot 0611 was higher on abaxial leaf surfaces and bract margins. Lint yield of Arkot 0611 was 10.3% higher than DP 393 over 16 replicated field tests at four sites in Arkansas. By location, lint yields of Arkot 0611 were equal to lint yields of DP 393 on Sharkey clay soil at Keiser (north) and on silt loam soil at Rohwer (south), but were 19.4% higher on silt loam soil at Judd Hill (north) and 11.7% higher on silt loam soil at Marianna ( central Arkansas). Compared to DP 393, lint yields of Arkot 0611 were produced with higher lint percentage, number of seed per area, lint index, fibers per seed, and fiber density ( estimated number of fibers per unit area of seed surface); and lower seed size (seed index). Compared to DP 393, Arkot 06 I 1 produced higher leaf pubescence rating ( 4.0 vs. 2.5), marginal bract trichome density (34.0 vs. 24.9 trichomes cm-1), open boll percentage (66 vs. 61 %), lint percentage (40.8 vs. 39.5), seed per area(8.3% higher), lint index (7.6 vs. 7.5 g), fibers per seed (l 0.1 % higher), fiber density (13. 7% higher), fiber elongation (7.8 vs. 6.6%); equal plant height and stem pubescence; and lower seed index (I 0.3 vs. 11.3 g), quality score (40 vs. 49), micronaire (4.77 vs. 4.96), fiber length (30.0 vs 29.7 mm), uniformity index (83.9 vs. 85.1 %), and fiber strength (300 vs. 326 kN m Kg-1). Arkot 0611 is resistance to all U.S. races of Xanthomonas citri ssp. malvacearum ( ex Smith 190 I) Schaad et al. 2007, the causal agent of bacterial blight. Arkot 0611 had lower damaged flowers (more resistance) than DP 393 in tests of resistance to tarnished plant bug [Lygus lineolaris (Palisot de Beauvois)]. Response of Arkot 06 I I to fusarium wilt [caused by Fusarium oxysporum Schlect. F. sp. vasinfectum (Atk.) Snyd. & Hans.] was equal to the ,resistant check, M-315.
