Enhancing microspore embryogenesis in diploid potato (Solanum tuberosum L. ssp. tuberosum) germplasm
Bibliographic record
Abstract
Abstract Doubled haploidy (DH) technology has been utilized in cultivated tetraploid potato (Solanum tuberosum L. ssp. tuberosum) to accelerate crop improvement; however very little work has been done with the diploid species. Experiments were undertaken to improve microspore embryogenic response in the diploid germplasm. Several factors influencing embryogenic responses were evaluated. An increase in calcium nitrate, a reduction in the plant growth regulators 6-benzyladenine (BA) and α-naphthaleneacetic acid (NAA), as well as an incubation temperature of 28 °C resulted in an increase in callus production and, in some cases, embryo-like structures. Validation of the modified protocol was conducted with both diploid and tetraploid potato germplasm with responses from both diploid and tetraploid. Monoploid and di-haploid plants were also regenerated from these microspore-derived calli.
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.

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.
