GRIN ID	PI 697030
Type	Breeding Germplasm
Species	Gossypium hirsutum
Description	Arkot 0822 is a conventional cotton germplasm line with morphological traits similar to 'UA248' (developed from same cross), 'DP 393' and 'UA48' (check cultivars), except Arkot 0822 has lower trichome density on abaxial leaves and on bract margins than the cultivars. Data from replicated field tests at four sites in Arkansas over six years indicated that lint yields of Arkot 0822 were equal to UA248 and exceeded lint yields of DP393 and UA48 at each location, except equal yields with DP 393 at Judd Hill. Over all locations, lint yields of Arkot 0822 were 7. 7 and 15.9% greater than DP 393 and UA48, respectively. Soils at all sites are silt loams, except the Sharkey clay at Keiser. Compared to UA248, Arkot 0822 produced higher lint index (8.2 vs. 7.7 g), seed index (11.8 vs. 11.3 g), fiber micronaire (4.91 vs. 4.54), and fiber elongation (7.0 vs. 6.5%); equal open boll percentage (56 vs. 56%), stem pubescence (5.6 vs. 5.5 rating), marginal bract trichome density (24.7 vs. 26.4 trichomes cm-1), lint fraction (40.5 vs. 40.1 %), seed ha-1 (15983 x 1000 vs 16312 x 1000), fibers per seed (15686 vs. 15816), fiber length (31.8 vs. 32.0 mm), fiber uniformity index (85.7 vs. 85.6%), and fiber strength (320 vs. 323 kN m kg-1); and lower plant height (98 vs. 103 cm), leaf pubescence rating (2.0 vs 3.5), fiber density (134 vs 144 fibers mm-2 of seed coat), and quality score (63 vs. 73). Arkot 0822 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 0822 (62%) was lower than UA48 (66%) and equal to DP 393 (60%) and UA248 (63%) in tests of resistance to tarnished plant bug [Lygus lineolaris (Palisot de Beauvais)]. As indicated by lint yield at Judd Hill location (site of high Verticillium wilt), response of Arkot 0822 to Verticillium wilt [caused by Verticillium dahliae Kleb] was equal to UA248 and more tolerant than DP 393 and UA48.
