Influence of Genetic Variation on Morphological Diversity in Accessions of Stevia Rebaudiana Bertoni
Bibliographic record
Abstract
Stevia rebaudiana, a non caloric natural sweetener is currently the available substitute to sugar. It is a genus of about 150 species of herbs and shrubs, a Compositae and a native to Paraguay. The aim of this study was to evaluate collected accessions of stevia and characterize their genetic divergence. In 2010, 10 stevia accessions were collected across different locations in Malaysia. At maturity they were evaluated using morphological parameters and collected data were subjected to‘t’ test analysis at p<.05 as follows-(i) Plant heights: MS012 & SBK were significant at p<.001 and p<.002 respectively. (ii) Number of branches: BGI & SBK were significant at p<.001 and p<.008 respectively.(iii) Number of corymbs: AZI was significant at p<.000, while BGI was significant at p<.033. (iv) Number of leaves: MS012 & MS007 were respectively significant at p<.000 and p<.008. (v) Plant leaf size: AZI was significant at p<.003, MS007 at p<.005, and MS012 at p<.019 and (vi) stem girth: MS012 & MRG were also significantly different at p<.000 and p<.001 respectively. MSO12, MS007 & SBK had loads of promising genetic traits in studied accessions.

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.
