Segregation of Genotypes at SSR Loci Among Double-cross F_1 Population in Maize
Bibliographic record
Abstract
Using maize inbred lines of Taixi19(o2o2),QCL 3021(o16o16)and QCL 5019(Wxwx)as parents,a Double-cross((Taixi 19×QCL 3021)×(Taixi 19×QCL 5019))F1 population was constructed.Twenty three F1 plants with o2o2 o16o16 Wxwx genotype were chosen as materials by using SSR markers at the o2 and wx loci,and linked to o16 locus.Fourteen polymorphic SSR markers among 3 parents were selected from 180 SSR markers distributed through whole genome of maize.Then the segregation analysis of the genotypes at the 14 SSR marker loci among the 23 plants was done.The results were as follows:first of all,the segregation of the genotypes at the SSR loci was mainly inclined towards the two parents of high lysine maize with o2 and o16 gene,respectively;secondly,4 kinds of normal genotypes and 3 kinds of abnormal genotypes were brought through the segregation;Thirdly,in the 4 kinds of normal genotypes,the segregation was significantly biased at 13 SSR loci.These results are valuable reference for the researches of genetic segregation and application of SSR marker.

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.
