Performance of ‘Golden Delicious’ Apple on 23Rootstocks at 12 Locations: A Five-Year Summary of the 2003 NC-140Dwarf Rootstock Trial
Bibliographic record
Abstract
In 2003, an orchard trial of apple [ Malus× sylvestris(L.) var. domestica(Bork.) Mansf.] dwarf rootstocks was established at 12 locations in Canada, Mexico, and the United States using ‘Golden Delicious’ as the scion cultivar. A core group of 11 rootstocks was planted at all locations. The four rootstocks included as industry standards were Malling 26 EMLA (M.26 EMLA), Budagovski 9 (B.9), M.9 Pajam2, and M.9 NAKBT337. The other seven rootstocks included selections from Russia (B), Cornell-Geneva (CG and G), Czech Republic (J-TE), and Germany (Pi Au); these included B.62396, CG.3041 [Geneva® 41], CG.5935 [Geneva®935], G.16, J-TE-H, and Pi Au56-83, and Pi Au51-4. Some locations also received two additional CG rootstocks, seven Japanese (JM) rootstocks, J-TE-G, or two Pi Au rootstocks. After five years, trees on J-TE-G were similar in size to B.9; trees on B.62396 and CG.3041 were similar in size to M.9 NAKBT337; trees on CG.5935, G.16, J-TE-H and M.9 Pajam2 were similar in size to M.26; and trees on Pi Au56-83, Pi Au51-4, Pi Au36-2 and JM.2 were larger than M.26 EMLA. For the first time in an NC-140 rootstock trial, several rootstocks have higher yield efficiency than M.26 EMLA and M.9 NAKBT337. Promising new rootstocks with very high yield efficiency included CG.5935, CG.3041, CG.5179 and J-TE-G.

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.
