The USDA Forest Service, Agricultural Research Service, intends to award a sole-source, firm-fixed-price contract for the genotyping of tropical-derived corn lines to support the Germplasm Enhancement of Maize (GEM) Project. Located at the North Central Regional Plant Introduction Station in Ames, Iowa, this project aims to broaden genetic diversity in U.S. Corn Belt breeding programs to improve disease resistance, drought tolerance, and pest resistance. The anticipated award date is September 28, 2026. The selected contractor will be responsible for comprehensive genotyping services, including DNA extraction, library preparation, kernel chipping, and sequencing using probe-in-solution target enrichment. The work requires the use of specific SNP marker panels to ensure comparability with historical GEM datasets, along with full bioinformatics analysis and quality control. Interested parties must contact the contracting officer, Laniece Nixon, within 10 calendar days of the notice to provide evidence that competition would be advantageous to the government.

NOTICE OF INTENT TO SOLE SOURCE
PSC: B599
NAICS: 541380
Size Standard: $19 Million
Project Location: North Central Regional Plant Introduction Station, Ames, IA 50011


This is a Notice of Intent to Sole Source. Requests for a solicitation will receive no response.



The USDA Forest Service, Procurement Operations, Agricultural Research Service (ARS), intends to award a sole‑source, Firm‑Fixed‑Price contract for genotyping tropical‑derived corn lines in support of the Germplasm Enhancement of Maize (GEM) Project.


This procurement is being conducted under the authority of FAR 12.102(a). For purchases not exceeding the Simplified Acquisition Threshold, Contracting Officers may solicit from one source after determining that only one source is reasonably available.


The GEM Project adapts exotic maize germplasm to broaden genetic diversity in U.S. Corn Belt breeding programs, improving traits such as disease resistance, drought tolerance, and pest resistance. Genotyping tropical‑derived corn lines is required to evaluate exotic genomic contributions and how genomic selection affects those contributions. To meet this need, the contractor must provide genotyping by target sequencing using probe‑in‑solution target enrichment; kernel chipping; DNA extraction with full quality control; DNA library preparation including fragmentation, end‑repair, A‑tail addition, adapter ligation, and barcoded amplification with qPCR quality checks; sequencing; and full bioinformatics analysis. Required SNP marker panels (~45,000 SNPs and ~10,000 SNPs) must match previously used GEM panels, capture hundreds of thousands of SNP clusters, and be evenly distributed across all 10 corn chromosomes. Panels must be developed from diverse temperate, subtropical, and tropical germplasm to ensure comparability with historical GEM datasets. The contractor must also perform sequencing quality control and read trimming, and provide a user‑friendly bioinformatics interface with reference comparisons, depth and coverage statistics, and annotation of SNPs, indels, STRs, and SSRs.


Anticipated Award Date: September 28, 2026.


Interested parties may identify their interest and capability to respond to this requirement by contacting the Contracting Officer, Laniece Nixon, at Laniece.Nixon@usda.gov, within 10 calendar days of this notice.


Any response must provide clear and convincing evidence that competition would be advantageous to the Government. Responses will be considered solely to determine whether a competitive procurement is appropriate. A decision by the Contracting Officer not to compete based on responses is solely at the Government’s discretion. No reimbursement will be made for costs associated with submitting capability information.

Green Mountain Finger Lakes Invasive Species Map and Control
Solicitation # 12444726Q0053
Solicitation 12444726Q0053 is a HUBZone Small Business set-aside request for quotations issued by the USDA Forest Service for the mapping and control of non-native invasive plant species within the Green Mountain and Finger Lakes National Forests. The contractor is responsible for providing all labor, equipment, and materials to survey, map, and treat invasive plants using manual, mechanical, physical, and chemical methods, specifically targeting areas within or adjacent to timber sales to prevent species spread during harvest activities. Key requirements include the use of GIS technology for data collection and the mandatory use of aquatic-safe herbicides near wetland areas. The period of performance is scheduled from January 1, 2027, to December 31, 2027, with work performed in Vermont. The contract is a performance-based service agreement requiring a licensed Vermont commercial pesticide applicator to be on-site during all treatment activities. Award will be based on best value, evaluating the technical approach, past experience, and price reasonableness. Deliverables include the treatment of woody and non-woody invasive plants via cut stump, basal bark, and foliar applications, as well as detailed population surveying. Quality is ensured through 100 percent visual inspections by the Contracting Officer's Representative, with an acceptable quality level requiring 100 percent of the project area to be treated and over 85 percent of the target infestation removed. Quotes are due by October 26, 2026, and a site visit is scheduled for October 22, 2026, at the USFS Manchester Ranger Station.
