Hello,

New Genotype Projects Available for the T3 Prediction Challenge

Three additional genotype datasets are now available in T3 and may support genomic prediction model development for the T3 Prediction Challenge. These additions expand historical depth, regional nursery coverage, and cross-program germplasm representation, providing additional training population options for genomic prediction analyses.

Protocol	Project	Breeding Program	Description
Wheat 3K	SWRN_USDA	Spring Wheat Public Breeders	Uniform Spring Wheat Regional Nursery (Performance & Scab) public entries genotyped with USDA-3K (USDA-SoyWheOatBar-3K); 1968–2024
GBS	CSU_2025_GBS	Colorado State University	Colorado State breeding lines available in T3
MRASeq-Kansas	KSU_MRASeq	USDA-ARS	USDA Regional Germplasm Observation Nursery (RGON) and Regional Performance Nursery (RPN) entries

Happy Predicting!
