Arkot JJ46 (Reg. No. GP‐890, PI 651855), Arkot 9610 (Reg. No. GP‐891, PI 651856), and Arkot 9620 JJ46 (Reg. No. GP‐892, PI 651857) are noncommercial breeding lines of cotton ( Gossypium hirsutum L.) released by the Arkansas Agricultural Experiment Station in September 2007. Arkot JJ46 was derived from a cross between ‘SG 125’ and ‘HyPerformer HS46’. Arkot 9610 was derived from a cross between ‘SG 404’ and Arkot 8606. Arkot 9620 was derived from crossing Arkot 8712 with an advanced breeding line. The lines were evaluated in replicated tests in Arkansas from 2003 through 2006. With some specific adaptation, lint yields of the lines were generally comparable to two check cultivars. Fiber quality, particularly fiber length, and line‐specific host plant resistance traits—resistance to Fusarium wilt [caused by Fusarium oxysporum Schlect. f. sp. vasinfectum (Atk.) Snyd. & Hans.], Verticillium wilt (caused by Verticillium dahliae Kleb.), bacterial blight [caused by Xanthomonas campestris pv. malvacearum (Smith) Dye], and tarnished plant bugs [ Lygus lineolaris (Palisot de Beauvois)]—make these lines valuable to cotton breeding programs.
