A total of 21 breeding lines and reference cultivars (11 Runner, four Spanish and six Virginia) were evaluated. All advanced breeding lines were high oleic.
Environmental conditions in 2013 were favorable for both Sclerotinia and southern blights, but more Sclerotinia blight was observed than southern blight. The field also was infested with root-knot and lesion nematodes.
The top three Runner entries in revenue and yield were ARSOK-R37 ($545/A, 3,468 lbs/A), ARSOK-R35 ($530/A, 3,401 lbs/A) and ARSOK-R60A ($513/A, 3,388 lbs/A). ARSOK-R35 also was among the Runner entries most resistant to Sclerotinia blight.
The Spanish entries did not differ statistically in yield or grade, but ARSOK-S140-1 OL had the greatest crop value ($439/A) and yield (3,001 lbs/A). ARSOK-S140-1OL, in addition to Tamnut OL06, had the least Sclerotinia blight. ARSOK-S140-1OL will be released as "Ole" in 2014.
The Virginia breeding line, ARSOK-V41, had the highest crop value ($609/A), grade
(74) and a large proportion of extra-large kernels (63 percent). GA11J and ARSOK-V31 were most resistant to pod rot.
