Abstract

fetched live from OpenAlex

CDC Ptarmigan is a soft white winter wheat (Triticum aestivum L.) cultivar that is eligible for grades of the Canada Western General Purpose (CWGP) wheat class. The CWGP class was introduced in 2007 to encourage the development and production of cultivars for the biofuel and livestock feed markets in western Canada. CDC Ptarmigan is an intermediate height, very high-yielding, stem and leaf rust susceptible, low protein concentration, soft kernel texture winter wheat cultivar that is adapted to the low rust hazard area of western Canada. A high yield potential of low protein concentration grain make CDC Ptarmigan a good fit for the CWGP class.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
