Description	Morphological traits (including height, leaf shape, and leaf color) of Arkot 0705 are similar to 'DP 393' (check cultivar). Arkot 0705 has equal density of trichomes on leaves, but lower density (less pubescence) on stems and the marginal of bracts. Over 16 replicated field tests at four sites in Arkansas, lint yields of Arkot 0705 exceeded lint yields of DP 393 by 10.7%, but were equal to DP 393 at Judd Hill (site having silt loam soil in north Arkansas). Over 12 locations of the 2015 Regional Cotton Breeders Testing Network test, Arkot 0705 produced higher lint yield than any other of the 28 entries. Compared to DP 393, lint yields of Arkot 0705 were produced with equal number of seed per area, seed size (seed index), and fiber density (estimated number of fibers per unit area of seed surface), but higher lint weight per seed (lint index) and number of fibers per seed. Compared to DP 393, Arkot 0705 produced higher lint percentage (40.6 vs. 39.3%), lint index (8.1 vs. 7.5 g), fibers per seed (4.2%), micronaire (5.09 vs. 4.89), and fiber strength (333 vs. 323 kN m kg·1); equal open boll percentage, number of seed per area, seed index, fiber density, fiber length, uniformity index, and elongation; and lower Q-score (47 vs. 54). Arkot 0705 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. In field tests, it demonstrated tolerance to Verticillium wilt (caused by Verticillium dahliae Kleb.). In small plot tests, Arkot 0705 was more resistant to tarnished plant bug [Lygus lineolaris (Palisot de Beauvois)] than the susceptible check and equal to DP 393.Response of Arkot 0705 to fusarium wilt [caused by Fusarium oxysporum Schlect. F. sp. vasinfectum (Atk.) Snyd. & Hans.] was equal to the resistant check, M-315. Note: Plants, from which seed were produced, were evaluated and determined to be free of Bt (BG 1 and BGII) and RR Flex transgenes.
