Abstract

fetched live from OpenAlex

AC Saltlander originated from seeds collected in Turkey by United States Department of Agricultural (USDA) scientists. Plants from these seeds were grown in a nursery near Logan, UT, where researchers at the USDA Forage and Range Research Laboratory selected desirable parents to obtain caespitose growth. In a collaborative project, selected germplasm of this natural hybrid was made available to the Semiarid Prairie Agricultural Research Centre (SPARC), Agriculture and Agri-Food Canada (AAFC) for salt-tolerance testing and improvement. A series of mass selection breeding cycles was conducted at Swift Current, where the resulting plants were evaluated for resistence to root-zone salinity, winter hardiness, and desirable plant morphology, including uniform plant colour, vegetative vigour, leafiness, seed-set, and freedom from plant pests. The progenies from each cycle were cloned, half of which were transported to the Agricultural Research Service Laboratory in Utah, and half intercrossed to develop AC Saltlander, a palatable forage with salinity tolerance equal to that of tall wheatgrass [Thinopyrum ponticum (Podp.) Lui & Wang]. Key words: Green wheatgrass, salt-tolerant forage, salinity, Elymus hoffmannii, perennial forage, reclamation grass

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.
