Genetic diversity in New Zealand populations of <i>Sclerotium cepivorum</i>
Bibliographic record
Abstract
Abstract Mycelial interactions were examined between 231 New Zealand isolates of Sclerotium cepivorum Berk., as well as 25 isolates from a further eight countries. Within the group of New Zealand isolates six mycelial compatibility groups (MCGs) were identified and named using reference strains obtained from the University of Guelph, Canada. Two new groups, presently only known from New Zealand, were identified. Heterogeneity was found both within and between fields in all regions. A subset of 51 S. cepivorum isolates was further investigated for genetic diversity using universally primed PCR (UP‐PCR) and random amplified polymorphic DNA (RAPD) analyses. When results were analysed separately, each primer distinguished one to three genetic groups. However, when the results from two primers (L15 and OPAX15) were combined, six genetic groups were revealed. The results, as shown by MCGs and molecular methods, demonstrate the presence of genetic diversity in New Zealand field populations of S. cepivorum.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
