Inheritance of seed coat colour in flax (Linum usitatissimum L.)
Bibliographic record
Abstract
Flax (Linum usitatissimum L.) is the second most important oilseed crop in western Canada.Seed colour is used in Canada to distinguish the two main market types from each other.Regular, high linolenic acid flax must have brown seed while "zero" linolenic acid solin flax must be yellow-seeded.The most frequent seed colours in flax are brown and yellow and are determined by genes at three loci (G, Bl and D).Yellow seed colour results when homozygous recessive alleles are present at any of the loci.A dominant allele for yellow seed colour as well as a recessive allele for variegated seed have been recently identified but their interaction to the other genes was unknown.Hence, the main objective of this research was to determine the allelic relationships among the various genes conditioning seed colour in flax.Eleven flax lines, five with a recessive yellow seed phenotype [(YSED2, YSED4, S95407 and S96071 (CDC recessive yellow)] and G-1186/94 (European recessive yellow), two dominant yellow seed (YSED18 and CPI84495), three brown seed (ED47, Vimy and CDC Bethune) and one variegated seed (M96006), were crossed in all possible combinations, excluding reciprocal crossings.Following these crosses, test crosses were performed using five USDA introductions in order to determine the seed colour alleles possessed by each parental line.The five USDA introductions (Minerva, Bolley Golden, Viking, Crystal and Bionda) had defined alleles for yellow seed colour.Chi-squared tests of goodnessof-fit to various one and two gene segregation ratios indicated that yellow seed colour in the CDC recessive yellow parents (YSED2, YSED4, S95407 and S96071) was conditioned by the recessive allele of the g locus.Yellow seed in the European recessive yellow was controlled by a recessive allele of a different locus, d.A dominant preparation and also his care for my well being.

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.
