Cytology Analysis on Potato Hybrid Asexual Lines of H-027×Longshu No.6 and H-027×Longshu No.7
Bibliographic record
Abstract
In order to clarify the cytogenetics characteristics of five superior asexual lines selected from the F1 population of two hybrid combinations H-027 × longshu No. 6 and H-027 × longshu No. 7,respectively,the pollen fertility and chromosome pairing configuration of these lines at pollen mother cell meiosis Ⅰ( PMCMⅠ) were analyzed using the conventional slide-preparing technique. The results showed that the pollen fertility rates of superior lines 7,16,17,18 and 26 from H-027 × Longshu 6 F1 hybrids were 18. 18%,59. 69%,19. 03%,16. 54% and 51. 14%,respectively; and the rates of superior lines 2,10,11,12 and 14 from H-027 × Longshu 7 superior F1 hybrids were 52. 13%,17. 26%,55,72%,60. 17% and 18. 72%,respectively. The chromosome pairing configurations of superior lines 7,16,17,18 and 26 from H-027 × Longshu6 were 3. 7Ⅰ + 6. 7Ⅱ + 4. 6Ⅲ + 4. 0Ⅳ,2. 7Ⅰ + 10. 8Ⅱ + 2. 4Ⅲ + 3. 7Ⅳ,4. 2Ⅰ + 6. 6Ⅱ + 4. 6Ⅲ + 3. 8Ⅳ,4. 7Ⅰ + 6. 1Ⅱ + 5. 3Ⅲ + 3. 6Ⅳ and 3. 9Ⅰ + 5. 8Ⅱ + 3. 4Ⅲ + 5. 5Ⅳ,respectively;and that of superior lines 2,10,11,12 and 14 from H-027 × Longshu 7 were 1. 7Ⅰ + 9. 5Ⅱ + 1. 9Ⅲ +4. 3Ⅳ,2. 5Ⅰ + 5. 3Ⅱ + 4. 7Ⅲ + 3. 7Ⅳ,2. 1 Ⅰ + 8. 8 Ⅱ + 1. 7 Ⅲ + 5. 7 Ⅳ,1. 9 Ⅰ + 14. 2 Ⅱ +1. 5Ⅲ + 2. 5Ⅳ and 6. 1Ⅰ + 7. 7Ⅱ + 3. 6Ⅲ + 3. 9Ⅳ,respectively.

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.
