Title

Leveraging historical trials to predict Fusarium head blight resistance in spring wheat breeding programs

Charlotte Brault; Emily J. Conley; Andrew J. Green; et al. The Plant Genome 2025. doi:10.1002/tpg2.20559

Other claims from this paper (4)

Method / resource Reproducing kernel Hilbert space was the best prediction method across settings with mean accuracy 0.63.
Method / resource Training set optimization was useful for two traits.
Method / resource Prediction of unrelated breeding populations significantly decreased accuracy, although some traits and populations retained encouraging values.
Method / resource Adding the URSN population increased prediction accuracy up to 0.19 as the number of breeding-program training lines fell.

Other claims from this paper (7)

Observation Tree volume did not differ significantly between sites for stands up to 70 years old.
Observation Tree volume differed significantly between sites in older stands.

Observation Mean tree volume on similar sites did not differ significantly among subdistricts in a forest district.
Method / resource Forest-district strata were larger and had more plots than subdistrict strata.
Method / resource District-wide stratification significantly reduced volume standard error.
Method / resource District-wide stratification improved forest-inventory effectiveness.
