Abstract

fetched live from OpenAlex

An association between early maturity and tawny pubescence has been observed in short‐season soybean [ Glycine max (L.) Merr.]. The objectives of this study were to determine if a single locus controls early maturity; and if there is a new locus linked to E1 and T or, alternatively, a third allele at the E1 locus. A cross was made between ‘Harosoy’ isolines OT89‐5 ( e3e3 e4e4 ) and OT94‐47. PI 196529 was the donor of early maturity in the backcrossing program which developed OT94‐47. A total of 229 F 2 plants and the parents were grown under 20‐h photoperiods produced by incandescent lamps. OT94‐47 flowered in 43 ± 1.4 d, OT89‐5 flowered later in 57 ± 4.2 d, and the F 2 population fit a 3 late: 1 early flowering ratio. Early‐flowering F 2 plants produced F 3 families that flowered similarly to OT94‐47. Later‐flowering F 2 plants either segregated for flowering date or flowered similarly to OT89‐5. To test for allelism with E1 and linkage with T , a cross was made between OT93‐26 ( E1E1 e3e3 e4e4 TT ) and OT94‐47. F 2 plants were classified as parental types or intermediate and equivalent to OT89‐5 in maturity. Maturity and pubescence color were recorded in 376 F 3 progeny rows. The data did not fit a single locus model or a two loci dominant epistasis model (12:3:1). The E7 allele was partially, but not completely, dominant over the e7 allele. Therefore, a new locus E7 is proposed. Using the F 3 segregation data, linkage between T and E1 was estimated to be 1.3 ± 0.6 centimorgan (cM). Linkage between E1 and E7 was estimated to be 6.2 cM and linkage between E7 and T was estimated to be 3.9 cM. E7 is a new flowering, maturity, and photoperiod sensitivity locus tightly linked to both E1 and T E7E7 results in later flowering and maturity, and sensitivity to long photoperiods produced by incandescent lamps when compared to e7e7

Teacher imitation

Not 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.
