Impacts What was accomplished under these goals?
1. Variety Releases: We had two varieties that were released in 2013 namely: a)"NuMex 01"- It is a high oleic Valencia peanut (Arachis hypogaea L. subsp. fastigiata var. fastigiata) cultivar, developed by the New Mexico Agricultural Experiment Station and released on September 17, 2013. NuMex 01 originated from a cross made between ‘New Mexico Valencia A’ (NM Valencia A) and ‘Brantley’. NM Valencia A has predominantly 3 to 4-seeded pods, while Brantley has mostly two-seeded large Virginia pods. Pedigree selection was practiced based on oil quality as determined by high oleic (O)/linoleic (L) fatty acid ratio), pod size and shape, seeds per pod, seed size, testa color, market type (Valencia), maturity, yield, and grade characteristics. The selected segregants with these characteristics were advanced by single seed descent method until F4. Phenotypically uniform progenies were bulk harvested to conduct yield trials in F5. Performance tests in replicated trials across eastern New Mexico and west Texas began in 2010 and continued until 2012. NuMex 01 was tested under identity as NM083092. It matures in 130 days, similar to the control cultivar, NM Valencia A. Averaged across fifteen season-locations, NuMex 01 has produced 13% higher pod yield and showed 4% greater 100-seed weight than NM Valencia A (average pod yield 3068 kg ha-1; 100 seed weight 46.5 g). NuMex 01 is the first high oleic Valencia peanut cultivar released (O/L ratio 23.3 compared to 1.1 in NM Valencia A). It has better taste and good roasted flavor attributes. b. "Schubert" - Itis a high yielding, high oleic, early-maturing spanish-type peanut (Arachis hypogaea L. subsp. fastigiata var. vulgaris) cultivar, with improved shellout. Schubert was tested under the experimental designation TxL054520-34. Replicated line yield tests began in the F8 generation in 2007 and ran through 2010. Schubert matures approximately one to two weeks earlier than OLin. Yield averaged 526 kg/ha higher than for OLin, and shellout was 2.2 percentage points higher. Seed size was slightly larger than for the checks, 51.8 g/100 sound mature kernels, compared to 50.2 and 48.1 g/100 SMK for OLin and Tamspan 90, respectively. Schubert produces a higher proportion of medium seed than does either check cultivar, and a smaller proportion of split seeds. Resistance to Sclerotinia minor Jagger was not different from OLin or Tamspan 90. The objectives of releasing this line are to provide growers with a higher-yielding, high-oleic cultivar for the spanish market, with better maturity,.

Progress 01/01/12 to 12/31/12
Outputs OUTPUTS: A) We have made few crosses involving Valencia-C with Brantley release cultivar from North Carolina State University which is a Virginia type peanut that has disease resistance and are high oleic in oil content. The F4 materials that were selected with high yield and Valencia type pods were evaluated for oil content and two of the promising lines are showing high oleic ratio of 26 compared to non-high oleic variety Valencia-C of 1.0. The Oleic acid (18:1) was 80% and linoleic acid (18:2) was 3% in the newly selected F4 material. B) Collaborative research was initiated between NMSU and USDA, ARS, to develop SSRs for high throughput genotyping. We have generated SSR-enriched libraries, sequenced them using Roche 454 platform, and designed 879 SSR primer sets. We are testing the first 288 primer sets to find polymorphism on some of the populations that are being developed at NMSU. C) We assessed genetic diversity, a key component to the success of developing improved cultivars with desirable agronomic and quality traits. Seventy-eight U.S. Valencia core collection accessions together with 36 Valencia accessions representing the global peanut mini-core collection were used to study population structure and diversity and identify genetically diverse Valencia germplasm for use in peanut breeding. Neighbor-joining clustering, principal coordinate analysis, and STRUCTURE analysis consistently separated the Valencia germplasm into five clusters with two distinct major groups. The first major group consisted of genotypes from South America (64%) with few accessions from Africa, North America, Caribbean, and European regions. The second group consisted of accessions mostly from diverse regions of Africa, North and South America, Asia, and the Caribbean. However, the structuring was not related to the geographic origin and several admixtures were observed. D) Two advanced lines will be tested this year for early maturity along with the check cultivar Valencia-A and Valencia-C in eastern New Mexico and west Texas. We plan to test for maturity by digging at two digging dates (a) normal digging dates around 125 to 130 days. (b) Early digging dates will be dug between 115 to 120 days. We also plan to do flavor analysis to maintain Valencia taste and red skin color. E) Three mapping populations of cultivated x cultivated Valencia peanuts have been initiated in collaboration with ICRISAT. At present they are in F5 generation and we plan to do parental polymorphism using SSR markers that were developed above in objective (B). PARTICIPANTS: Nothing significant to report during this reporting period. TARGET AUDIENCES: Nothing significant to report during this reporting period. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts We are planning to release two Valencia cultivars with high oleic content. We have generated SSR-enriched libraries, sequenced them using Roche 454 platform, and designed 879 SSR primer sets. The information generated in this study and phenotyping of this material for biotic and abiotic stress responses and yield-quality traits will facilitate selection of trait-specific, genetically diverse parents for developing Valencia peanut cultivars with a broad genetic base.

The F4 materials that were selected with high yield and Valencia type pods were evaluated for oil content and two of the promising lines are showing high oleic ratio of 26 compared to non-high oleic variety Valencia-C of 1.0. The Oleic acid (18:1) was 80% and linoleic acid (18:2) was 3% in the newly selected F4 material. Peanut being an under represented crop in terms of genome sequencing and physical mapping that needs a comprehensive markers in genotype selection for genetic mapping population. A collaborative research was initiated between NMSU peanut breeding program and National Peanut Research Scientist Dr. Renee Arias at USDA, ARS, Dawson lab to develop SSRs for high throughput genotyping. We have generated SSR-enriched libraries, sequenced them using Roche 454 platform, and designed 879 SSR primer sets. We are in the process of testing the first 288 primer sets to find polymorphism on some of the populations that are being developed at NMSU. Seventy-eight U.S. Valencia core collection accessions together with 36 Valencia accessions representing the global peanut mini-core collection were used to study population structure and diversity and to identify genetically diverse Valencia germplasm for use in peanut breeding. Fifty-two simple sequence repeats loci amplified 683 alleles, with an average of 13 alleles per locus. The mean polymorphism information content and gene diversity, respectively, were 0.270 and 0.335. The pairwise genetic distance ranged from 0.143 to 0.474, with an average of 0.631. Neighbor-joining clustering, principal coordinate analysis, and STRUCTURE analysis consistently separated the Valencia germplasm into five clusters with two distinct major groups. The first major group consisted of genotypes from South America (64%) with few accessions from Africa, North America, Caribbean, and European regions. The second group consisted of accessions mostly from diverse regions of Africa, North and South America, Asia, and the Caribbean. However, the structuring was not related to the geographic origin and several admixtures were observed. Six mapping populations of cultivated x cultivated Valencia peanuts have been initiated in collaboration with ICRISAT. At present they are in F4 generation and will be tested for parental polymorphism using SSR markers that were developed above in objective (B).

PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts The information generated in this study and phenotyping of this material for biotic and abiotic stress responses and yield-quality traits will facilitate selection of trait-specific, genetically diverse parents for developing Valencia peanut cultivars with a broad genetic base. This project will contribute to the overall development of Valencia peanuts and enhanced market opportunities for American peanut producers.

Progress 01/01/10 to 12/31/10
Outputs OUTPUTS: The molecular characterization of 114 Valencia peanuts (78 accessions from US Valencia core and 35 accessions from global mini core and 1 control cultivar from ICRISAT) representing various geographical regions of the world was performed using microsatellite markers. Out of 100 primer pairs tested, 52 polymorphic primers amplified a total of 683 alleles. The number of alleles ranged from 2 to 28 per locus with a mean of 13.13 alleles per primer pair. Mean gene diversity and PIC value for all the alleles were 0.3496 and 0.2805, respectively. Based on Jaccard's coefficient of genetic similarity, accessions were clustered using unweighted pair group and the dendrogram was generated in the NTSYS-pc 2.20e. Two major clusters A and B sharing 30% similarity were obtained. Cluster A consisted of accessions predominantly from South American region. The cluster B consisted of an intermix of accessions from North America, South America, Africa, Asia and Caribbean regions. A single accession ICG6201 from the Caribbean region separated from rest of all the accessions and shared a similarity of only 10 %. Principal component analysis (PCA) depicted two major clusters with few accessions scattered apart in minor groups. In our study 41.18% of variation was explained by the first three PCs. The genetic diversity observed in Valencia core and global mini core could be used in breeding Valencia cultivars. From the global peanut core collection we have selected 3 accessions namely, JUG 3 for drought, ICGV 92267 for early maturity and ICG 7243 with high SPAD chlorophyll. We have made crosses of all these three accessions with our local check variety namely Valencia - C to develop three mapping populations. At present these are in F3 stage and we will be advancing these populations in 2011 growing season. PARTICIPANTS: Nothing significant to report during this reporting period.
