Description	Morphological traits of Arkot 0712 are similar to 'DP 393' (check cultivar) except Arkot 0712 has higher trichome density on leaves, bract margins and stems and is shorter in height. Over 16 replicated field tests at four sites in Arkansas, lint yields of Arkot 0712 were equal to lint yields of DP 393 at each location. Over I 2 locations of the 2015 Regional Cotton Breeders Testing Network test, Arkot 0712 produced the 20th highest yield of 28 entries. Compared to DP 393, lint yields of Arkot 0712 were produced by higher rumber of seed per area; equal lint percentage and fibers per seed; and lower weight of lint per seed (lint index), seed size (seed index), but had lower weight of lint per seed (lint index), seed index and fiber density (estimated number of fibers per unit area of seed surface). Compared to DP 393, Arkot 0712 produced higher open boll percentage (61 vs. 57%), leaf pubescence (3.8 vs. 2.8), stem pubescence (5.5 vs. 5.1 ), marginal bract trichomes ( 42.1 vs 3 1.6), seed per area (8. 7% higher), Q-score ( 62 vs. 54 ), fiber length (30.5 vs. 29.7 mm), and elongation (7.4 vs. 6.8%),); equal lint percentage and fibers per seed; and lower plant height (4.0% shorter), lint index (7.0 vs. 7.5 g), seed index (10.6 vs. 11.2 g), fiber density (4.8% fewer), micronaire (4.48 vs. 4.85), uniformity index (84.2 vs. 85.2%) and fiber strength (294 vs 323 kN m kg-1). Arkot 0712 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 small plot tests, Arkot 0712 was more resistant to tarnished plant bug [Lygus lineolaris (Palisot de Beauvois)] than the susceptible check and equal to DP 393. Response of Arkot 0712 to fusarium wilt [caused by Fusarium oxysporum Schlect. F. sp. vasinfectum (Atk.) Snyd. & Hans.] was equal to the resistant check, M-315.
