Invasion and reproduction by rootlesion nematode (Pratylenchus penetrans) differs among selected lines of red clover (Trifolium pratense)
Bibliographic record
Abstract
Eighteen cultivars and breeding lines of red clover (Trifolium pratense) were evaluated in a greenhouse study for their relative response to inoculation by the root-lesion nematode (Pratylenchus penetrans). The incidence of plants invaded and the nematode concentration in the roots were generally related but not always. One cultivar (Florex) had a low incidence of plants being invaded, but a high concentration of nematodes in the roots of invaded plants. Three entries (CRS 15, CRS 5, and CRS 11) displayed a low incidence of plants being invaded and a low concentration of nematodes in the root. One cultivar, AC Kingston, was judged to be highly susceptible, while the remaining entries had differing invasion incidences and differing concentrations of root-lesion nematodes in the roots.
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 machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
