Abstract
Partial amphiploids are lines that contain 42 (38-42) wheat and 14 (14-18) alien chromosomes. They are derived by backcrossing wheat onto hybrids between wheat and either Thinopyrum intermedium (6x) or Th. ponticum (10x). GISH analysis has shown that, with possibly one exception, the alien genomes (chromosome sets) in partial amphiploids are found to be hybrids i.e. composed of chromosomes from more than one alien genome. The individual partial amphiploids are meiotically stable and nearly perfectly fertile, but hybrids between different lines were characterized by varying numbers of unpaired chromosomes and consequently variable degrees of sterility. Translocated chromosomes involving different Thinopyrum genomes or Thinopyrum and wheat genomes were found in partial amphiploids and consequently in the addition lines derived from them. Partial amphiploids have proven to be an excellent tertiary gene pool for wheat improvement, containing resistance to biotic stresses not present in wheat itself. Resistance to Barley Yellow Dwarf Virus (BYDV) and Wheat Streak Mosaic Virus (WSMV) have been found in partial amphiploids and addition lines derived from both Th. intermedium and Th. ponticum. Excellent resistance to Fusarium head blight has been found on a Th. intermedium chromosome that had substituted for chromosome 2D in wheat. Genes for resistance to leaf rust and stem rust have already been incorporated into wheat and tagged with molecular markers.

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 it
