Registration of GA‐BatSten1 and GA‐MagSten1, two induced allotetraploids derived from peanut wild relatives with superior resistance to leaf spots, rust, and root‐knot nematode

  •  372-378
  •  7 May 2021

Core Ideas

  • Wild relatives of peanut harbor alleles that confer strong resistances to diseases and pests.
  • Most wild species are diploid while cultivated peanut (Arachis hypogaea) is tetraploid.
  • Development of wild-derived tetraploids is essential for allele transfer to peanut.
  • We produced two fertile induced allotetraploids, GA-BatSten1 and GA-MagSten1.
  • GA-BatSten1 and GA-MagSten1 are resistant to pests and diseases and available for breeding.

Registration of the Rice Diversity Panel 1 for Genomewide Association Studies

Abstract

The Rice Diversity Panel 1 (Reg. No. MP-6, NSL 500357 MAP) (RDP1) is a collection of 421 purified, homozygous rice (Oryza sativa L.) accessions (GSOR 301001 through GSOR 301421; GSOR 312001 through 312020) representing the broad range of genetic variation within O. sativa. The accessions include both landraces and elite rice cultivars, which were classified into five subpopulation groups, including indica (95 accessions) and aus (60), which belong to the Indica varietal group, and tropical japonica (106), temperate japonica (111), and aromatic (Group V) (16) which comprise the Japonica varietal group. Thirty-three accessions are classified as admixtures because they shared <60% ancestry with a single group. The seed, with and without the hull, and panicle morphology of each accession were documented with digital images, and the RDP1 was phenotyped for morphological, developmental, and physiological traits. Genotypes for 36,901 SNP loci are publicly available for additional genomewide association mapping studies. In this report, we evaluate three grain quality traits on the RDP1: apparent amylose content (AC), gelatinization temperature as measured by alkali spreading value (ASV), and protein content. Canonical discriminant analysis revealed AC was the quality trait most closely correlated with subpopulation structure, followed by ASV. These traits indicate that temperate japonica was the most distinct group, whereas aus and indica could not be differentiated, and the aromatic accessions were closest to tropical japonica.

M6: A Diploid Potato Inbred Line for Use in Breeding and Genetics Research

Abstract

M6 (Reg. No. GP-1, BS 228) is a diploid self-compatible inbred line of the potato wild relative Solanum chacoense. It is a vigorous, homozygous breeding line derived by self-pollinating the diploid wild potato relative S. chacoense for seven generations. While most wild Solanum species are self-incompatible, this clone is homozygous for the dominant self-incompatibility inhibitor gene Sli. In addition, it is homozygous for 90% of single-nucleotide polymorphism markers in the Infinium Array developed by the SolCAP consortium. M6 is vigorous and both male and female fertile, producing seeds in crosses to diploid cultivated and wild potato germplasm. These traits enable us to systematically develop diploid inbred lines, which was not possible in potato breeding until the discovery of Sli. M6 produces tubers under both short and long photoperiods, unlike other wild potato relatives. In addition, M6 has several desirable traits, including high dry matter content, good chip processing quality, and resistance to soft rot and Verticillium wilt. M6 is being used to develop recombinant inbred line populations.

Registration of ‘USDA‐N8002’ Soybean Cultivar with High Yield and Abiotic Stress Resistance Traits

Abstract

‘USDA-N8002’ (Reg. No. CV-519, PI 676972) is a conventional maturity-group (MG) VIII soybean [Glycine max (L.) Merr.] cultivar developed and released by the USDA-ARS in September 2015. USDA-N8002 is the first North American MG VIII soybean cultivar exhibiting drought resistance and high yield potential. It is the first U.S. release derived from PI 471938 (25% by pedigree) and the second MG VIII release derived from PI 416937 (12.5% by pedigree). USDA-N8002 exhibits slow or delayed canopy-wilting, sustained N fixation during drought stress, and a water-conserving transpiration response when exposed to atmospheric vapor pressure deficit. USDA-N8002 is an F4–derived cultivar from a cross of USDA-ARS cultivar N7002 and USDA-ARS breeding line N98-7265. USDA-N8002 was yield tested in a total of 74 environments across the southeastern United States in the United Soybean Board Southern Soybean Diversity Yield Trials MGVII-VIII (Diversity Trials), the USDA Uniform Soybean Tests– Southern States, Uniform Group VIII (Uniform Tests), and the North Carolina Official Variety Tests MG VII–VIII (NC-OVT). USDA-N8002 yielded 7% greater (p < 0.05) than the check cultivar N8001 in the Uniform Tests, 5% greater in the NC-OVT (p < 0.05), and 5% greater in the Diversity Trials (p = 0.09). The diverse ancestry, drought resistance, and high yield potential of this release suggest it can provide new options for soybean breeding and production in the southeastern United States.

Registration of ‘Tifguard’ Peanut

Abstract

‘Tifguard’ (Reg. No. CV-101, PI 651853) is a runner-type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar released by the USDA-ARS and the Georgia Agricultural Experiment Stations in 2007. Tifguard was developed at the University of Georgia Coastal Plain Experiment Station, Tifton, GA. Peanut cultivars are available that have high resistance to the peanut root-knot nematode [Meloidogyne arenaria (Neal) Chitwood race 1] or spotted wilt caused by tomato spotted wilt tospovirus (TSWV). However, no cultivars exist that have resistance to both pathogens. Our research objective was to combine resistance to both pathogens in a single cultivar. Breeding populations were developed by hybridizing the TSWV-resistant ‘C-99R’ with the nematode-resistant ‘COAN’. Selection for nematode resistance was conducted using standard greenhouse screening techniques. Selection for TSWV resistance was conducted in the field with natural virus infection. A breeding line (C724-19-15) was selected that had high resistance to both pathogens. Tifguard exhibited higher resistance to TSWV and higher yield than standard check cultivars when grown in fields with little or no nematode pressure. Because of its high level of resistance to both TSWV and M. arenaria, Tifguard had significantly higher yield than all others entries when grown in two locations with high pressure from both pathogens. This cultivar should be valuable for peanut growers who have to deal with both pathogens.
