Registration of ‘Fieldstar’ Hard Red Spring Wheat
Bibliographic record
Abstract
‘Fieldstar’ (Reg. No. CV‐1067, PI 663950) (Registration. No. 6328 by the Plant Variety Registration Office, Plant Production Division, Seed Section, Canadian Food Inspection Agency, Agriculture and Agri‐Food Canada [AAFC]) hard red spring wheat ( Triticum aestivum L.) was developed and released by the Cereal Research Centre of AAFC and meets the end‐use quality specifications of the Canada western red spring wheat market class. Fieldstar is a partial backcross derivative of ‘McKenzie’, with ‘Clark’ as the donor of the Sm1 gene for midge resistance, which produces a product that reduces the palatability of developing seeds to wheat midge larvae ( Sitodiplosis mosellana Géhin). Fieldstar is adapted to the eastern wheat growing regions of the Canadian prairies as determined by the Central Bread Wheat Cooperative Registration Test in 2004, 2005, and 2006. For registration testing, the performance of Fieldstar was estimated using the varietal blend Fieldstar VB, which consisted of 90% Fieldstar and 10% ‘Waskada’. The grain yield of Fieldstar was similar to that of the highest‐yielding checks, McKenzie and ‘Superb’, and expressed resistance to leaf rust (caused by Puccinia triticina Eriks.) and stem rust (caused by P. graminis Pers.:Pers. f. sp. tritici Eriks. E. Henn.) and intermediate resistance to common bunt [caused by Tilletia tritici (Bjerk.) R. Wolff and T. laevis Kuhn in Rabenh.], loose smut [caused by Ustilago tritici (Pers.) Rostr.], and Fusarium head blight [FHB; caused by Fusarium graminearum Schwabe; teleomorph Gibberella zeae (Schwein.) Petch]. Fieldstar was released because of its combination of high yield, resistance to wheat midge, and intermediate resistance to FHB.

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.
