Abstract

fetched live from OpenAlex

CTH2 is the first flue-cured tobacco (Nicotiana tabacum L.) hybrid recommended for commercial release in Canada. Yields and economic returns of CTH2 are significantly higher than the check varieties, Delgold and CT157. It has uniform growth both in the greenhouse and in the field, and is resistant to black root rot disease (Chalara elegans Nag Raj and Kendrick, causal agent). Leaf quality traits of CTH2 are far superior to Delgold, as well as commercial varieties that are also immune to black root rot disease. Key words: Nicotiana tabacum L., tobacco, hybrid, male sterility, black root rot, cultivar description

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.

Full frame distilled prediction

Teacher imitation

Not 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.
