Sullivan

Sullivan is a Virginia-type peanut breeding line selected in a program to develop cultivars with multiple disease resistances.

Characteristics

• Alternate branching pattern
• Intermediate runner growth habit
• Medium green foliage
• 45% jumbo pods
• 40% fancy pods
• 42% extra-large kernel content
• Seed with tan seed coat averaging 931 mg per seed

Disease Resistance

Partially resistant to the most common diseases in the Virginia-Carolina peanut production area:

• Early leaf spot caused by Cercospora arachidicola Hori
• Cylindrocladium black rot (CBR) caused by C. parasiticum Crous
• Wingfield & Alfenas
• Sclerotinia blight (SB) caused by S. minor Jagger
• Tomato spotted wilt tospovirus (TSWV)

High-oleic

Sullivan has the high-oleic trait patented by the University of Florida. This trait includes modified fatty acid content, with elevated oleic fatty acid content and depressed linoleic and palmitic acid content that increases the shelf life of the seeds and products made from them. Compared with normal-oleic cultivars, Sullivan should exhibit the extended shelf life that has been documented in high­-oleic lines.

Yield

Yield is superior to most existing Virginia-type cultivars, except Bailey and Sugg. In the NCSU Advanced Yield Tests averaged across more than 20 tests conducted over six years, Sullivan yielded significantly more than CHAMPS, Gregory, NC-V 11, Perry and Phillips. Pod characteristics and grade of Sullivan were most similar to those of Bailey, NC-V 11, and Perry. Sullivan has fairly bright pods of the dominant type for that line.

In the Peanut Variety and Quality Evaluation (PVQE) trials, Sullivan was not different (P<0.05) from Sugg or Bailey in yield. Sullivan had high value per acre, although not as high as Bailey. However, compared with Florida Fancy, Sullivan was numerically if not statistically higher in yield and value with greater brightness of jumbo and fancy pods.

Flavor

The roasted peanut, sweet, and bitter attributes of flavor in Sulivan grown in North Carolina were quite good compared with Virginia-type cultivars, and also in comparison with runner-type flavor standards Florunner and Georgia Green.

Cultivar Development

Sullivan was developed by a combination of pedigree selection and modified pedigree selection (single-seed descent) among and within families descended from a three-way cross. The initial cross was made in the winter of 2002-2003 using breeding line N03079FT as a female and high-oleic line N02059ol as a male. N03079FT is a disease-resistant sister line of the Virginia-type cultivar Bailey. N02059ol is a backcross derivative of Perry. In the summer of 2003, the hybrid was backcrossed a single time to N03079FT.
