Evaluation of Native Rose Selections for Rose Hip Production in Prince Edward Island
Bibliographic record
Abstract
This study was carried out to determine the potential for the commercial production of rose hips in Prince Edward Island, Canada. Native rose (Rosa spp.) ecotypes were propagated by cuttings taken from wild populations. The experiment was conducted at the Agriculture and Agri-Food Canada, Crops and Livestock Research Centre, Harrington Research Farm in Harrington, PEI in 2005. A replicated trial consisting of 30 wild rose selections was first harvested in 2006. Data from the top 14 ecotypes are reported on based on yield potential. Mean fruit weight ranged from 1.01 g to 1.62 g per fruit; seeds per fruit ranged from 33.5 to 66.3; flesh to seed ratio ranged from 1.34 to 2.57 g/g. Generally, first flowering was observed at 190 Julian day number (JDN) followed by full flowering at 199 JDN. Mean rose hip yield averaged over the first four harvest years ranged from 411 to 2,000 kg ha−1. In 2009, selection s26 and s30 produced 3,634 and 2,676 kg ha−1, respectively. Selection s26 had the largest canopy and best survival rating.

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.
