Comparative Agronomic Performance of 15 Saskatoon (Amelanchier AlnifoliaNutt.) Cultivars During TheirFirst Seven Years of Growth
Bibliographic record
Abstract
This study quantitatively characterizes 15 different saskatoon cultivars grown in replicated trials at two sites (University of Saskatchewan and Moonlake, SK) during their first seven years of growth from 1992 to 1998. The 15 cultivars included ‘Bluff’, ‘Buffalo’, ‘Forestburg’, ‘Honeywood’, ‘JB30’, ‘Martin’, ‘Nelson’, ‘Northline’, ‘PAR 90’, ‘Parkhill’, ‘Pearson II’, ‘Pembina’, ‘Smoky’, ‘Success’, and ‘Thiessen’. Data were collected on survival, shoot growth, stem growth, suckering, blossoming time, fruit size, and yield. Growth as measured in this study, did not differ among the cultivars in most years. However, in 1994, ‘Thiessen’ had a greater current season's shoot growth than most of the other cultivars. Cultivars that produced the fewest suckers (4 to 10/plant in total over the seven years) included ‘Forestburg’, ‘Martin’, ‘Nelson’, ‘PAR 90’, ‘Pembina’, ‘JB30’, and ‘Thiessen’. ‘Buffalo’, ‘Bluff’, and ‘Parkhill’ produced the most suckers with a mean of 34, 36 and 64 suckers per plant, respectively, over seven years. Cultivars that tended to bloom earlier in the season included ‘Bluff’ and ‘Parkhill’; ‘Thiessen’ and ‘Martin’ also blossomed relatively early. ‘Pembina’, ‘Success’, ‘Northline’ and ‘JB30’ were among the last of the cultivars to blossom. ‘Martin’ and ‘Thiessen’ had the largest fruit with mean diameters of 14.2 and 13.9 mm, respectively. The cultivars, ‘Success’, ‘Bluff’ and ‘Parkhill’ had the smallest fruit with mean diameters of 10, 10.9 and 11 mm, respectively. The top yielding cultivars included ‘Pearson II’, ‘Smoky’ and ‘Honeywood’, with a mean cumulative yield over the seven years of 8.5 kg per plant. The yield of ‘Pembina’ was unusually low with a mean cumulative yield of just over 2 kg per plant.

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.
