“…Host plant resistance will provide the most effective solution to managing Sclerotinia blight in any peanut production system, but is essential to organic production. Several Valencia cultivars have been released for production including New Mexico Valencia A (Hsi and Finkner, 1972), New Mexico Valencia C (Hsi, 1980), GenTex 101, 102, and 136 (Borden Peanut Company, Portales, NM), Georgia Red (Branch and Hammons, 1987), Georgia Valencia (Branch, 2001), and NuMex01 (Puppala and Tallury, 2014), but none have documented levels of resistance to Sclerotinia blight.…”

Cultivated peanut, the second most economically important legume crop throughout the United States and the third most important oilseed in the world, is consistently threatened by various diseases and pests. Sclerotinia blight, (causal agents Sclerotinia sclerotiorum (S. sclerotiorum) and Sclerotinia minor Jagger (S. minor))is a major threat to peanut production in the Southwestern U.S., Virginia, and North Carolina and can reduce yield by up to 50% in severely infested fields. S. sclerotiorum has now been reported in areas of eastern New Mexico and west Texas where all U.S. grown Valencia peanuts are produced, commonly in organic cropping environments. Host plant resistance provides the most effective solution to managing Sclerotinia blight, especially in organic systems where pesticide use is not an option for disease control. To date, no Valencia cultivars with Sclerotinia blight resistance have been released. In this study, the Valencia peanut core germplasm collection was genotyped with a Simple Sequence Repeat (SSR) marker associated with Sclerotinia blight resistance in order to identify potential germplasm for use in breeding to develop Valencia peanut cultivars resistant to the disease. Thirty accessions from the Valencia peanut core collection have profiles consistent with other genotypes that exhibit less that 5% incidence of Sclerotinia blight under heavy disease pressure. The identified accessions, after field evaluation, may serve as potential sources of Sclerotinia blight resistance in Valencia peanut breeding programs.

“…During each of 3 yr (Table 4), Georgia‐Val/HO had a significantly higher oleic/linoleic (O/L) ratio than two other high‐oleic valencia‐type peanut cultivars, ‘NuMex 01’ (Puppala & Tallury, 2014) and TAMVal OL14. Also, Georgia‐Val/HO had a significantly higher 3‐yr average 36.1:1 O/L ratio compared with 1.7:1 for Georgia Valencia.…”

‘Georgia‐Val/HO’ (Reg. no. CV‐143, PI 695316) is a new high‐yielding, high‐oleic, large‐podded, large‐seeded, valencia‐type peanut (Arachis hypogaea L. ssp. fastigiata var. fastigiata) cultivar. Georgia‐Val/HO has an atypical semi‐prostrate growth habit and medium maturity, but typical valencia three seed per pod and red testa color. It also has moderate resistance to tomato spotted wilt disease. Georgia‐Val/HO was released by the Georgia Agricultural Experiment Station in 2020 and was developed at the University of Georgia Coastal Plain Experiment Station, Tifton, GA. It was developed from an intersubspecific cross made in 2010 between two Georgia cultivars, ‘Georgia‐11J’ (ssp. hypogaea) and ‘Georgia Valencia’ (ssp. fastigiata). During 4 yr (2016–2019) averaged across two planting dates (April and May), Georgia‐Val/HO had significantly less total disease incidence and higher pod yield, total sound mature kernel (TSMK) grade, and dollar values compared with six other valencia cultivars in Georgia. Georgia‐Val/HO had significantly higher overall performance at both early April and optimum May planting dates. Georgia‐Val/HO combines high yield, TSMK grade, and dollar value with large pods and seed and the high O/L ratio trait for longer shelf life of peanut and peanut products.

“…The ratio of oleic to linoleic acid content (O/L) ranged from 2.24 to 28.59 in commercial cultivars and from 0.94 to 6.37 in PI accessions except for PI 461451 which had an O/L ratio of 28.79 comparable to the best performing cultivars. Among cultivars, Red River Runner / PI 665474 (Melouk et al 2013), Florida-07 / PI 652938 (Gorbet and Tillman 2009), Florida Fancy / PI 654368 (Branch 2007), FloRun 107 / PI 663993 (Tillman and Gorbet 2015), and NM309-2 / PI 670460 (Puppala and Tallury 2014), had the highest O/L ratio, ranging from 7.14 to 28.6. While on the low end, O/L ranged from 2.39 to 3.13 for Georgia-06G / PI 644220 (Branch 2007), Bailey / PI 659502 (Isleib et al 2011), and Jupiter (Anon.…”

The fatty acid composition of seed oil is a major determinant of the flavor, shelf-life, and nutritional quality of peanuts. Major QTLs controlling high oil content, high oleic content, and low linoleic content have been characterized in several seed oil crop species. Here we employ genome-wide association approaches on a recently genotyped collection of 787 plant introduction accessions in the USDA peanut core collection, plus selected improved cultivars, to discover markers associated with the natural variation in fatty acid composition, and to explain the genetic control of fatty acid composition in seed oils. Overall, 251 single nucleotide polymorphisms (SNPs) had significant trait associations with the measured fatty acid components. Twelve SNPs were associated with two or three different traits. Of these loci with apparent pleiotropic effects, 10 were associated with both oleic (C18:1) and linoleic acid (C18:2) content at different positions in the genome. In all 10 cases, the favorable allele had an opposite effect - increasing and lowering the concentration, respectively, of oleic and linoleic acid. The other traits with pleiotropic variant control were palmitic (C16:0), behenic (C22:0), lignoceric (C24:0), gadoleic (C20:1), total saturated, and total unsaturated fatty acid content. One hundred (100) of the significantly associated SNPs were located within 1000 kbp of 55 genes with fatty acid biosynthesis functional annotations. These genes encoded, among others: ACCase carboxyl transferase subunits, and several fatty acid synthase II enzymes. With the exception of gadoleic (C20:1) and lignoceric (C24:0) acid content, which occur at relatively low abundance in cultivated peanut, all traits had significant SNP interactions exceeding a stringent Bonferroni threshold (α = 1%). We detected 7,682 pairwise SNP interactions affecting the relative abundance of fatty acid components in the seed oil. Of these, 627 SNP pairs had at least one SNP within 1000 kbp of a gene with fatty acid biosynthesis functional annotation. We evaluated 168 candidate genes underlying these SNP interactions. Functional enrichment and protein-to-protein interactions supported significant interactions (p-value < 1.0E-16) among the genes evaluated. These results show the complex nature of the biology and genes underlying the variation in seed oil fatty acid composition and contribute to an improved genotype-to-phenotype map for fatty acid variation in peanut seed oil.
