• A total of 23 breeding lines and reference cultivars (16 runner, two Spanish and five Virginia market types) were evaluated in fields highly infested with the Sclerotinia blight fungus. All advanced breeding lines were high oleic.
• Environmental conditions in 2014 were favorable for Sclerotinia blight. Little southern blight or pod rot were observed.
• The top three runner entries in revenue were Tamrun Ol11 ($917/A), ARSOK-R37 ($899/A) and ARSOK-R35 ($879/A). These three runner entries also demonstrated considerable resistance to Sclerotinia blight (25 percent to 28 percent disease incidence) compared to the highly susceptible Tifrunner (80 percent) and Florida 107 (73 percent).
• The new Spanish peanut cultivar Ole produced higher revenue ($784/ A), yield (5,203 lbs/A) and grade (70 percent TSMK) than the small-seeded runner Georgia 04S ($546/ A, 3,860 lbs/ A; 66 percent TSMK). In addition, Ole was significantly more resistant to Sclerotinia blight (7.9 percent) than Georgia 04S (49 percent).
• Virginia entries did not differ statistically in crop value, but the top three numerical entries were ARSOK-V30B ($832/A), ARSOK-V41 ($798/A) and ARSOK-V31 ($780/A). ARSOK-V30B and ARSOK-V31 were significantly more resistant (21 percent to 23· percent) to Sclerotinia blight than the other three entries (55 percent to 62 percent). ARSOK-V30B will be released as 'VENUS' in 2015.
