NC 20
High-yielding, high-oleic, large-seeded Virginia-Type peanut
NC 20 is a high-oleic large-seeded Virginia-type peanut selected in a conventional breeding program.
Characteristics
- Alternate branching pattern
- Intermediate runner growth habit
- Medium green foliage
- 29% jumbo pods
- 30.4% fancy pods
- 35% extra-large kernel content
- Seed with tan testa averaging 906 mg per seed
Disease Resistance
Moderately resistant or tolerant to the four most common diseases in the Virginia-Carolina peanut production area:
- Early leaf spot caused by Passalora arachidocola (formerly Cercospora arachidicola)
- Late leaf spot caused by Nothopassalora personata (formerly Cercospora personatum)
- Sclerotinia blight (SB) caused by Sclerotinia minor
- Tomato spotted wilt tospovirus (TSWV)
NC 20 provides greater yields under heavy leaf spot pressure compared to currently available Virginia-type peanuts varieties.
High-oleic
NC 20 has the high-oleic seed oil trait patented by the University of Florida. The high-oleic trait produces an array of changes in the fatty acid composition of peanut oil compared with normal-oleic cultivars, most notably the elevation of oleic acid and the reduction of linoleic and palmitic acid content. Compared to normal-oleic cultivars like Bailey, NC 20 exhibits the extended shelf life associated with high-oleic lines like Bailey II, Emery, Sullivan, and Wynne.
Yield
Yield of NC 20 is similar to existing Virginia-type cultivars including Bailey II, Bailey, Emery, and Sullivan. In the NCSU Advanced Testing Program for yield, consisting of 18 trials across six years at three locations, NC 20 exceeded yields of Bailey II, Bailey, Wynne, and Sullivan and was similar to the yields of Emery. NC 20 has bright jumbo and fancy pods.
In the regional PVQE trials (2017 – 2019), NC 20 had a greater yield than all pf the currently available Virginia-type peanuts with similar crop value to Bailey and Bailey II. During the regional performance testing, it was determined that NC 20 has a slightly later maturity date than Bailey and Bailey II; however, this did not affect the oleic acid content, with an average of 81.5% and an oleic-to-linoleic acid ratio of 21.2.
Flavor
The roasted peanut and sweetness attributes of NC 20 were similar to Bailey and compared well with runner-type flavor standards of Georgia Green and Georgia-06G.
Cultivar Development
NC 20 was developed using 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 between the breeding line N01015T and a sister breeding line to Gregory (N000098ol). The resulting F7 derived line (X02083 [F2-01-S-01-S-05: F7]) was then crossed to the variety Sugg.
