Evaluation of Soybean Varieties in the Northern SCN Regional Soybean Test—SCN Regional Test IIin West Central Iowa
Bibliographic record
Abstract
The Northern SCN Uniform/Preliminary (UT/PT) Regional Soybean Test is used to evaluate soybean varieties produced by public breeding programs in the northern portion of the United States and Canada. Lines are evaluated in locations with moderate to high SCN pressure. In 2015, five public breeding programs participated in the Northern SCN UT-PT II Trials (Uniform Test II and Preliminary Test II). Public breeders are allowed to enter varieties into the UT-PT Trials in exchange for growing locations for the trial. Material entered into the UT-PT Test is generally in advanced stages of a breeding program. Lines are evaluated one year in Preliminary Testing before being entered in Uniform Tests. Lines usually are evaluated in Uniform trials for two or three years prior to release as new varieties. The UT-PT Soybean Trials are an efficient method for soybean breeders to have a wider geographic range of field evaluations on advanced lines and to evaluate advanced lines from other public programs, which could be used as parents in future crossing. These results also are used in cultivar releases, publications, and publicity, once a variety is released.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
