Yield of Yellow Onion Cultivars in Eastern Oregon and Southwestern Idaho
Bibliographic record
Abstract
Potential new onion ( Allium cepa L.) cultivars for commercial production in eastern Oregon and southwestern Idaho are evaluated annually in yield trials conducted at the Malheur Experiment Station, Oregon State University, Ontario, Ore. Bulb yield and market grade were determined in field trials for 63 yellow onion cultivars and lines in 1996 and for 49 cultivars and lines in 1997. Marketable yield out of storage in January ranged from 478 to 1131 cwt/acre (54 to 127 Mg·ha -1 ) in 1996, and from 383 to 912 cwt/acre (43 to 102 Mg·ha -1 ) in 1997. Marketable yields of `9003C', `Seville', `El Charro', `Sunre 1430', `El Padre', `Golden Security', `Bravo', and `X 202' were greater than 1000 cwt/acre (112 Mg·ha -1 ) in 1996. In 1997, marketable yields of `Seville', `Bravo', `Quest', `T-433', `9003C', `Goldstar', `Superstar', `RNX-10020', `Vision', and `Sweet Perfection' were greater than 850 cwt/acre (95 Mg·ha -1 ). Of the 30 cultivars evaluated both years, the average marketable yields of `Seville', 9003C, `Bravo', `Quest', and `Sweet Perfection' were among the highest. Many others showed potential for high yields and merit further evaluation. In both years, most bulbs of all selections graded jumbo [3 to 4 inch (7.6 to 10.2 cm) diameter] and colossal [>4 inch (10.2 cm) diameter], and only a few cultivars had more than 2% medium-size [2.25 to 3 inch (5.7 to 7.6 cm) diameter] bulbs. Infection by neck rot ( Botrytis allii Munn.) and plate rot [ Fusarium oxysporum f. sp. cepa (H. N. Hans.) W.C. Snyder & H.N. Hans.] during storage was more severe in 1996 than in 1997, but in general, most cultivars showed relatively low levels of these diseases in both years. Averaged across all cultivars, bolting was evident in less than 1% of bulbs in both years.

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.
