Abstract

fetched live from OpenAlex

Genetic diversity in 91 accessions of 'Ai meng niu' and its pedigree was assessed using SSR markers. The 20 pairs of SSR informative primers generated a total of 120 alleles. Each pair of SSR primer could detect 3 to 9 alleles with an average of 6.0. Genetic similarities among 91 accessions ranged from 0.411 to 0.961, which indicated that genetic difference among them was significant. Ai meng niu and its Pedigrees could be clustered into four groups with UPGMA cluster analysis. It could be a suitable index for genetic divergences among wheat cultivars. The genetic diversities of Ai meng niu's Pedigree have the tendency of increasing with time slightly, This is related with using Ai meng niu and its Pedigrees repeatly of breeding units. A set of derived lines have been developed from crosses between Aimengniu and Shannong Fu 66, Shannong Fu 63, selecting parents of hybrid reasonably is significant.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
