‘SJM150’ Apple Rootstock
Bibliographic record
Abstract
SJM150' (St-Jean Morden 150) is a new rootstock resulting from a cross made in 1960 between Malus baccata 'Nertchinsk' and 'M.26' ('Malling 26' = M.16 • M.9).It is a new dwarfing apple rootstock developed at the Agriculture and Agri-Food Canada (AAFC) Research Station, St-Jean-sur-Richelieu, Quebec.It produces dwarf trees larger than 'Malling 9' (M.9) but smaller than 'Malling 26' (M .26).It was released because of its superior hardiness, ease of propagation, and similar to better efficiency and precocity compared with 'M.26' and 'M.9' in sandy loam soil (Khanizadeh et al., 2005).'SJM150' produces very low or no suckers compared with 'M.9' and the same amount of burr knots compared with 'M.9' and 'M.26'.'SJM150' was among the 56 hybrid seedlings of 'Nertchinsk' • 'M.26' to which 'McIntosh VC309' was budded in 1971 and planted in 1974 at Frelighsburg, Quebec, where it was evaluated until 1984 for hardiness, tree size, and efficiency (Granger et al., 1991) along with other semiadvanced SJP84 and SJM series (Khanizadeh et al., 2007).'SJM150' was planted in 1997 in replicated trials in several plots at the Frelighsburg, Quebec, and L'Acadie, Quebec, substations and also at two grower sites (Khanizadeh et al., 2000(Khanizadeh et al., , 2005)).

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.
