Variability and phylogenetic relationships of the Cucumis sativus L. species inferred from NBS-profiling and RAPD analysis
Bibliographic record
Abstract
Genetic variability of the Cucumis sativus species and its phylogenetic relationsips with other species of the genus were studied on the basis of RAPD marking and analysis of intra- and interspecific polymorphism of the nucleotide sequences of the NBS-LRR gene family in species of the genus Cucumis with the use of the NBS profiling method. According to RAPD analysis, cucumber cultivars from different geographic regions are highly similar, except for accessions k-3835 and k-3833 from Afghanistan. NBS profiling analysis revealed phylogenetically most distinct accessions expected to be characterized by specificity of resistance: k-3845 from Uzbekistan, k-3851 from Kyrgyzstan, line 701, k-3835 and k-3833 from Afghanistan, k-2757 and k-3079 from Netherlands, vr.k. 908 from Canada, k-2926 from Bulgaria, Russian cultivars Monastyrskii, Izyashchnyi, and Lel'. Three essentially different groups of species were distinguished, and the C. sativus species (subgenus Cucumis) was found to be distant from the species belonging to the subgenus Melo.

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.
